+- 3 Grunt test tasks are available now: `grunt test`, `grunt test:handsontable`, `grunt test:walkontable`
+
+## [0.8.16](https://github.com/warpech/jquery-handsontable/tree/v0.8.16) (Mar 26, 2013)
+
+Features:
+- [Handsontable in Handsontable editor](http://handsontable.com/demo/handsontable.html)
+- performance and code quality fixes
+- `height` and `width` settings can now be functions (that return a number)
+
+Bugfixes:
+- autocomplete menu did not reset `<li>` margin
+- `destroy()` of one Handsontable instance made other instances on the same page unfunctional
+- Autocomplete (Bootstrap Typeahead) did not allow empty string as a value ([#254](https://github.com/warpech/jquery-handsontable/issues/254))
+- outsideClickDeselects : false disables all focus in other inputs outside the table ([#408](https://github.com/warpech/jquery-handsontable/issues/408))
+- can't scroll all the way horizontally ([#430](https://github.com/warpech/jquery-handsontable/issues/430))
+- scrollable Handsontable does not work well with Twitter Bootstrap ([#224](https://github.com/warpech/jquery-handsontable/issues/224))
+- weirdly shrinking table when height attribute was not set ([#461](https://github.com/warpech/jquery-handsontable/issues/461))
+
+Other:
+- trying to load a string as a data source now throws an error
+
+## [0.8.15](https://github.com/warpech/jquery-handsontable/tree/v0.8.15) (Mar 18, 2013)
+
+Features:
+- new callbacks: `onSelectionEnd` and `onSelectionEndByProp` (see [README.md](https://github.com/warpech/jquery-handsontable) for usage information)
+- new demo page [Callbacks](http://handsontable.com/demo/callbacks.html)
+- **breaking change:** `getSelected` method output has slightly changed. Was: [`topLeftRow`, `topLeftCol`, `bottomRightRow`, `bottomRightCol`]. Is: [`startRow`, `startCol`, `endRow`, `endCol`]. This gives information about the direction of the selection - now you can tell if the selection started from left to right or otherwise.
+
+Bugfixes:
+- `outsideClickDeselects: false` disables all focus in other inputs outside the table ([#408](https://github.com/warpech/jquery-handsontable/issues/408))
+- copy paste in Mac Safari didn't work ([#470](https://github.com/warpech/jquery-handsontable/issues/470))
+- table jumps back and forth when scrolling ([#432](https://github.com/warpech/jquery-handsontable/issues/432))
+- destroy doesn't unload context menu functionality ([#434](https://github.com/warpech/jquery-handsontable/issues/434))
+- throwed error when Enter key was pressed on autocomplete cell in the last row ([#497](https://github.com/warpech/jquery-handsontable/issues/497))
+- Autocomplete in strict mode allows values other than predefined ([#405](https://github.com/warpech/jquery-handsontable/issues/405))
+
+## [0.8.14](https://github.com/warpech/jquery-handsontable/tree/v0.8.14) (Mar 14, 2013)
+
+Features:
+- now, your data source can be a function! See the last section of the [Array, object and function data sources](http://handsontable.com/demo/datasources.html) page for examples (fixes [#471](https://github.com/warpech/jquery-handsontable/pull/471), [#435](https://github.com/warpech/jquery-handsontable/pull/435), [#261](https://github.com/warpech/jquery-handsontable/issues/261))
+- also the column `data` property can be a function as well! Again, see the last section of the [data sources](http://handsontable.com/demo/datasources.html) page for examples
+- new methods: `countEmptyRows`, `countEmptyCols`, `isEmptyRow`, `isEmptyCol`. You can define your own functions for `isEmptyRow` and `isEmptyCol` (see [README.md](https://github.com/warpech/jquery-handsontable) for details)
+
+Bugfix:
+- replace reference to non-existent Exception with Error ([#494](https://github.com/warpech/jquery-handsontable/pull/494))
+- textarea copyPaste covering page elements ([#488](https://github.com/warpech/jquery-handsontable/issues/488), [#490](https://github.com/warpech/jquery-handsontable/issues/490))
+
+## [0.8.13](https://github.com/warpech/jquery-handsontable/tree/v0.8.13) (Mar 12, 2013)
+
+This release adds a `min-width: 600px` to the test suite to make sure that 100% of current tests are passing in [Travis CI](https://travis-ci.org/warpech/jquery-handsontable) (PhantomJS) as well as in the desktop browsers.
+
+There are still many bugs to be fixed, but now it should be much easier to keep the increasing quality of future versions.
+
+## [0.8.12](https://github.com/warpech/jquery-handsontable/tree/v0.8.12) (Mar 12, 2013)
+
+This release doesn't really bring any improvements for the end user but is a big step towards test automation. From now on, a push to the `master` branch triggers a [Travis CI](https://travis-ci.org/warpech/jquery-handsontable) build that performs automated testing using [grunt-contrib-jasmine](https://github.com/gruntjs/grunt-contrib-jasmine). Thanks @bollwyvl for your [help](https://github.com/warpech/jquery-handsontable/pull/474)!
+
+As a side effect, tests are now be runnable using PhantomJS. To run the test suite in PhantomJS, type `grunt test` (first run `npm install` to make sure you have all dependencies installed). PhantomJS runs the test suite much faster than desktop browsers, so it may come handy.
+
+Bugfixes:
+- `destroy` method now clears all pending timeouts
+
+## [0.8.11](https://github.com/warpech/jquery-handsontable/tree/v0.8.11) (Mar 8, 2013)
+
+Features:
+- this may be a **breaking change** for some applications: Now the third parameter to the `alter` method tells the amount of rows/columns to be inserted/removed. This adds more consistency to the API. ([#368](https://github.com/warpech/jquery-handsontable/issues/368), [67fe67c](https://github.com/warpech/jquery-handsontable/commit/67fe67c3cf6bf4df47c02ea8c7aa6802864e97de))
+- merged pull request [#474](https://github.com/warpech/jquery-handsontable/pull/474) - Travis-CI integration. The tests don't pass yet but don't worry about it yet. It is a work in progress on complete test automation. Making all tests pass on Travis CI headless browser may take few more days or weeks :)
+
+Bugfix:
+- again, this may be a **breaking change** for some applications: Fix very long standing inconsistency. Restored original `setDataAtCell` requirement of the second parameter to be a column number (as described in [README.md](https://github.com/warpech/jquery-handsontable) since always). If you happen to experience an error in `setDataAtCell` after upgrade, change your usage of this method to the new method `setDataAtRowProp` ([#284](https://github.com/warpech/jquery-handsontable/issues/284), [90e1b67](https://github.com/warpech/jquery-handsontable/commit/90e1b6765cf3aa6e0e5c5a9156b9d45da74fa055))
+- new methods `setDataAtRowProp` and `getDataAtRowProp` that set/get data according to the property name in data source. See [README.md](https://github.com/warpech/jquery-handsontable) for clarification ([#284](https://github.com/warpech/jquery-handsontable/issues/284), [90e1b67](https://github.com/warpech/jquery-handsontable/commit/90e1b6765cf3aa6e0e5c5a9156b9d45da74fa055))
+- merged pull request [#266](https://github.com/warpech/jquery-handsontable/pull/266) - fix countCols for arrays with column settings
+
+## [0.8.10](https://github.com/warpech/jquery-handsontable/tree/v0.8.10) (Mar 7, 2013)
+
+Bugfix:
+- inline cell styles applied by cell renderer were not removed on table scroll ([#353](https://github.com/warpech/jquery-handsontable/issues/353), [#376](https://github.com/warpech/jquery-handsontable/issues/376), [a9b328d](https://github.com/warpech/jquery-handsontable/commit/a9b328d2fcbcb7e7a05f1d2494a1f9062bd17a37))
+
+Docs:
+- simplify CSS for demo pages (get rid of `bottomSpace` classes)
+- refresh the style of jsFiddle links
+
+## [0.8.9](https://github.com/warpech/jquery-handsontable/tree/v0.8.9) (Mar 6, 2013)
+
+This is a feature release of a new cell type. For people waiting for some bug fixes, I promise next release will focus on fixing some important bugs!
+
+Features:
+- **Date cell type**. Updated pages [Date](http://handsontable.com/demo/date.html) and [Cell types](http://handsontable.com/demo/renderers.html). Solves issue [#431](https://github.com/warpech/jquery-handsontable/issues/431)
+- refactored the `text`, `autocomplete` and `date` cell editors to share as much code as possible
+
+## [0.8.8](https://github.com/warpech/jquery-handsontable/tree/v0.8.8) (Mar 4, 2013)
+
+Bugfixes:
+- `startRows`/`startCols` option did not work as described in README.md. This parameters should be only taken into account when NO data source is provided ([5c865ba](https://github.com/warpech/jquery-handsontable/commit/5c865ba15dcb7d9f93a47b14aedfc96751bcbb7a))
+- finish editing should move the focus aways from textarea to table cell ([f4f6496](https://github.com/warpech/jquery-handsontable/commit/f4f649600311ba527c19dc2e8f73af2e764c54d6))
+
+## [0.8.7](https://github.com/warpech/jquery-handsontable/tree/v0.8.7) (Mar 1, 2013)
+
+Bugfixes:
+- use default cell editor for a cell that has declared only cell renderer ([#453](https://github.com/warpech/jquery-handsontable/issues/453), [a5c61a2](https://github.com/warpech/jquery-handsontable/commit/a5c61a26b9e833abd25afa31aee4199cc6810590))
+- copy/paste did not work on Mac since 0.8.6 ([#348](https://github.com/warpech/jquery-handsontable/issues/348), [463d5c9](https://github.com/warpech/jquery-handsontable/commit/463d5c918b85b2dc74df2669047134c23ae15fcc))
+- global shortcuts (like CTRL+A) should be blocked when cell is being edited ([8363008](https://github.com/warpech/jquery-handsontable/commit/8363008c3756ea869f50b2ad8a213839a50ad807))
+- numeric cell editor did not convert cell data to number type when data source was an object ([b09f6d3](https://github.com/warpech/jquery-handsontable/commit/b09f6d3666d238ac0ae849937152baffa6fb2824))
+- another attempt to solve scrolling to the top of table on any key press if the top is not on the screen ([#348](https://github.com/warpech/jquery-handsontable/issues/348), [d37859b](https://github.com/warpech/jquery-handsontable/commit/d37859b6acdaef0be8b886b33404144c7cf21227))
+
+## [0.8.6](https://github.com/warpech/jquery-handsontable/tree/v0.8.6) (Feb 27, 2013)
+
+Features:
+- **Numeric cell type**. Updated pages [Numeric](http://handsontable.com/demo/numeric.html) and [Column sorting](http://handsontable.com/demo/sorting.html). Solves issues [#443](https://github.com/warpech/jquery-handsontable/issues/443), [#397](https://github.com/warpech/jquery-handsontable/issues/397), [#336](https://github.com/warpech/jquery-handsontable/issues/336). Partially solves issue [#121](https://github.com/warpech/jquery-handsontable/issues/121) ([a052013](https://github.com/warpech/jquery-handsontable/commit/a052013049ccf6ca75a7104ddeaaec2f84961f93))
+- autoColumnSize feature is now aware of renderer functions (before this, cells rendered with autocomplete and numeric renderer were too narrow) ([7770f8a](https://github.com/warpech/jquery-handsontable/commit/7770f8a499e5c21891308bdb4d1111bfc79dd2dc))
+
+Bugfix:
+- scrolls to top of table on any key press if the top is not on the screen ([#348](https://github.com/warpech/jquery-handsontable/issues/348), [290cde9](https://github.com/warpech/jquery-handsontable/commit/290cde93503686f1a89e5533662e3c9ca80d880e), [408f29d](https://github.com/warpech/jquery-handsontable/commit/408f29d6a65e797572adf45873780c3adfc0bf4d))
+- cell editor was using a wrong cell value if column order was manually changed ([#367](https://github.com/warpech/jquery-handsontable/issues/367))
+- cell editor dimensions were not refreshed if table was rerendered during editing
+- fix recalculation of container dimensions after window resize ([#400](https://github.com/warpech/jquery-handsontable/issues/400), [#428](https://github.com/warpech/jquery-handsontable/issues/428))
+
+Other:
+- reimplement cell editing abstraction. Now TextEditor `<textarea>` is decoupled from cell selection and copy/paste keyboard handling ([14e4cc1](https://github.com/warpech/jquery-handsontable/commit/14e4cc1d61d92b49317aed53604b87cdd1f522b0), [1eb01bd](https://github.com/warpech/jquery-handsontable/commit/1eb01bdcc975dec4fe8f2557a668d057d34b65d2), [f2b412f](https://github.com/warpech/jquery-handsontable/commit/f2b412f50027d3b4594bef464994ca8ad4f551a6), [e5af5d7](https://github.com/warpech/jquery-handsontable/commit/e5af5d7c8cbd8990398e8029c2955d7f8e22386c))
+- upgrade Bootstrap Typeahead to v2.3.0
+- build system now requires Grunt 0.4.0 (read instructions how to upgrade here: http://gruntjs.com/upgrading-from-0.3-to-0.4) ([3ebed1d](https://github.com/warpech/jquery-handsontable/commit/3ebed1ddb771b1d21ebf810f82df004755d420f4), [6d01ae5](https://github.com/warpech/jquery-handsontable/commit/6d01ae528ed84171d72f34eb3f25f4137f96a7ec))
+
+## [0.8.5](https://github.com/warpech/jquery-handsontable/tree/v0.8.5) (Feb 18, 2013)
+
+Bugfix:
+- clear currentRowClassName and currentColumnClassName when refreshing selections ([#398](https://github.com/warpech/jquery-handsontable/issues/398), [8df5de9](https://github.com/warpech/jquery-handsontable/commit/8df5de9a345a650a8e588bc4fe3da5d3e2075972)) - thanks @jaycfields
+
+## [0.8.4](https://github.com/warpech/jquery-handsontable/tree/v0.8.4) (Feb 17, 2013)
+
+Features:

+- optimize jquery-autoresize plugin: arclones element is emptied before injecting another node
+- new configuration options `currentRowClassName` and `currentColClassName` along with new example page [Highlight current row & column](http://handsontable.com/demo/current.html) [TODO: write tests]
+- [Manual column resize](http://handsontable.com/demo/column_resize.html)
+- [Column sorting](http://handsontable.com/demo/sorting.html)
+- compability: automatic column size is asserted `true` when `colWidths` option is not provided
+- apply automatic column size when double clicked on manual resize handle [TODO: write tests]
+- Scroll example page describes difference between available [column stretching modes](http://handsontable.com/demo/scroll.html) (all, last [default], none)
+- manual column move
+
+Breaking changes:
+- `loadData` no longer sends list of changes to `onChange` callback. That was not performant. Now if sends `null` changes object and `loadData` as source string.
+
+Bugfixes:
+- overflow auto only worked when declared in inline style (not in CSS class) (issue #339 point 6)
+- during initialization, sliders were shown for a while in the top left corner
+- scrolling issues (#343, #331, partially #360)

+
+Features:

+- auto stretch [TODO: write more]
+
+Bugfix:
+- `selectCells` did not perform multiple selection when given 4 parameters
+
+## [0.8.1](https://github.com/warpech/jquery-handsontable/tree/v0.8.1) (Jan 6, 2013)
+
+Bugfixes:
+- fixed error when loading a new data source with fewer rows/columns
+- using `minCols` with `columns` option caused an infinite loop. Now `columns` length sets a fixed number of columns (options `startCols`, `minCols`, `maxCols` will be ignored when `columns` is set) (fix #334)
+- onChange was triggered before data was rendered (fix #333)
+- public `destroy` method did not unbind Handsontable events (fix #335)
+- fix error when data row was externally removed while scrolling
+
+Other changes:

+- JSFiddle links now also work in [Context Menu demo page](http://handsontable.com/demo/contextmenu.html)
+- tests are now passing 100% in Chrome, FF, IE9 and Opera. Tests are 99% passing in IE7-8, but remaining 1% does not affect normal operation in these browsers
+
+## [0.8.0](https://github.com/warpech/jquery-handsontable/tree/v0.8.0) (Jan 2, 2013)
+
+After series of bugfixes in last 3 beta version, this is the first stable release in 0.8.x branch. From now on, I will try to update critical issues more frequently.
+
+New features since 0.8.0-beta3:
+- new methods `rowOffset`, `colOffset`, `countVisibleRows`, `countVisibleCols`
+- new callback `onCreateRow` [TODO: write tests]
+- `dataSchema` can now be a function that returns object/array [TODO: write tests]
+- when using `overflow: auto`, only relevant scrollbars should be displayed (first reported by @dansabirov / #295)
+- fixed scrolling with arrow keys
+- column title can be given as `columns[].title` (not only colHeaders[]) [TODO: write tests]
+- column width can be given as `columns[].width` (not only colWidths[]) [TODO: write tests]
+- column type can be set using simple strings: `autocomplete`, `checkbox`
+
+Other changes:
+- public methods `colCount`, `rowCount` are removed. Use `countRows()` and `countCols()` public methods instead
+- public methods `setCellReadOnly`, `setCellEditable` are removed. Use `readOnly` cell property to make a cell read-only. See `demo/readonly.html` for examples
+- options `minWidth`, `minHeight` are removed. Their definitions were to blurry and usage case too limited. Use `width` and `height` options instead and provide as many rows/columns in your data source as you need
+- add `render` method to README.md
+
+Bugfixes since 0.8.0-beta3:
+- enter on last row/col should add more rows/cols if minSpareRows/minSpareCols > 0
+- double clicking on fill handle fills the column to the last non-empty row
+- pressing enter/tab in autocomplete moves to next row/column
+- CTRL+A works slow on large data sets (as reported by @brivazac / #295)
+- CTRL+A, CTRL+C sequence did not work well if CTRL was not released
+- page up/page down worked wrongly
+
+Known issues:
+- clicking on cell & row borders has no effect (first reported by @cscribner / #295)
+- copy of large selection (5k, 10k, 100k rows etc) freezes IE8 (first reported by @itanex / #295). Below 1k rows works fine. The only solution I can think of right now is to set copy limit in IE8 to 1000 rows.
+- paste of large selection (100k rows) freezes Firefox (first reported by @ravio / #303)
+- autocomplete does not work with empty field in source; autocomplete strict mode looks broken (as reported by @MDron / #303)
+- scrolling mouse wheel/page up/page down should not block the window scroll if the first row/last row was reached
+- page up/page down does not behave exactly as in Google Docs (moves selected cell to first visible row). This is because transformStart implies scrollToCell. It should be decoupled sometime in future
+
+## [0.8.0-beta3](https://github.com/warpech/jquery-handsontable/tree/v0.8.0-beta3) (Dec 18, 2012)

+- CTRL+A then Delete did not remove redundant empty rows in scroll example (as reported by @ravio / 303)
+- fill handle (drag-down) feature is currently broken (as reported by @chaowarat / 301)
+- CTRL+Enter while editing multiselection did not work (should apply the value to all the selected cells)
+- now works in IE7
+
+Other changes since 0.8.0-beta2:
+- removed `jquery.ui.position.js` from `jquery.handsontable.full.js`, because it seems to have no effect (explained in `demo/contextmenu.html`)
+
+## [0.8.0-beta2](https://github.com/warpech/jquery-handsontable/tree/v0.8.0-beta2) (Dec 14, 2012)

+- fixed known issue "table width and height is now configured using `width` and `height` settings"
+- fixed error when clicking on row/column header (related to @cscribner / #295)
+- fix copy-paste in Chrome (thanks @ravio  / #295)
+- `getRowHeader()` referenced to colHeaders instead of rowHeaders (thanks @marint / #295)
+- fix performance of `loadData` (thanks @codename- / #295)
+- now works in IE8, still not yet in IE7
+
+## [0.8.0-beta1](https://github.com/warpech/jquery-handsontable/tree/v0.8.0-beta1) (Dec 11, 2012)
+

+
+Bugfixes:
+- fixed CSS problems with Foundation framework
+
+Other changes:
+- Handsontable core properties `colCount`, `rowCount` do not exist anymore. Use `countRows()` and `countCols()` public methods instead

+
+Features:
+
+- new settings: `minRows`, `minCols`, `maxRows`, `maxCols` (fixes [#225](https://github.com/warpech/jquery-handsontable/issues/225))
+- `startRows` and `startCols` should now be only used to define how many empty rows should be created on grid initialization
+- now you can use `columns` to configure number of autocomplete items (fixes [#242](https://github.com/warpech/jquery-handsontable/issues/242))
+
+Bugfixes:
+
+- `loadData` now will remove empty rows from grid if new data source has less rows
+- new rows are now correctly created when using nested object data source ([#255](https://github.com/warpech/jquery-handsontable/pull/255))
+- copy and paste issues with nested object data source ([#250](https://github.com/warpech/jquery-handsontable/issues/250))
+
+## [0.7.4](https://github.com/warpech/jquery-handsontable/tree/v0.7.4) (Nov 19, 2012)
+
+Bugfixes:
+
+- fix error when pasting values to a grid with dataSchema (issue #237)
+- loadData should remove empty row if source data has more empty rows than allowed by minSpareRows (issue #239)
+- textarea dimensions were not updated if grid was rerendered while editing
+
+## [0.7.3](https://github.com/warpech/jquery-handsontable/tree/v0.7.3) (Nov 14, 2012)
+
+Features:
+
+- big news: build now contains full and minified JS and CSS packages. See [dist/](https://github.com/warpech/jquery-handsontable/tree/master/dist) directory for details.
+- added experimental "Edit in jsFiddle" link in [autocomplete example](http://handsontable.com/demo/autocomplete.html). If no issues are observed, I will add it to all example pages.
+
+Bugfixes:
+
+- fixed [issue with setCellReadOnly](http://stackoverflow.com/questions/13127501/sets-cell-to-be-readonly) that was reported on Stack Overflow.
+- fixed performance issue with cells being rendered twice in `loadData` (issue #233)
+
+## [0.7.2](https://github.com/warpech/jquery-handsontable/tree/v0.7.2) (Nov 12, 2012)
+
+Fixes exeption when editing cell in IE8 (issue #232) and problems when using Autocomplete with Ajax.
+
+Added Ajax example on [autocomplete.html](handsontable.com/demo/autocomplete.html)
+
+## [0.7.1](https://github.com/warpech/jquery-handsontable/tree/v0.7.1) (Nov 9, 2012)
+
+Mosty fixes for the Autocomplete feature as well as a new (easier) syntax for the Autocompelte. See [autocomplete.html](http://handsontable.com/demo/autocomplete.html) for examples. Old syntax should still work due to the [legacy layer](https://github.com/warpech/jquery-handsontable/blob/master/src/plugins/legacy.js).
+
+Features (described in [README.md](https://github.com/warpech/jquery-handsontable)):
+
+  - new public method `destroyEditor` (#229).
+
+## [0.7.0](https://github.com/warpech/jquery-handsontable/tree/v0.7.0) (Nov 5, 2012)
+
+Please note that this release has partial incompability with previous releases. It is step in a direction to make Handsontable more flexible and customisable.
+
+Adds binding to object data source (prior versions only allow 2-dimensional array data source)
+Adds selective column rendering (using `columns` option)
+Now data is assigned to Handsontable as reference (prior versions had data copied)
+Adds custom cell types (currently text, autocomplete or checkbox)
+
+Features removed:
+
+ - Legend (use [cell renderers](http://handsontable.com/demo/renderers.html) instead)
+
+## [0.6.0](https://github.com/warpech/jquery-handsontable/tree/v0.6.0) (Sep 27, 2012)
+
+Please note that this release has partial incompability with previous releases, though it should affect only border cases.
+
+Potential incompabilities with version 0.5.1:
+  - public method `getData` no longer has `asReference` parameter (use `getDataReference` instead)
+  - to have scrollable grid, you must set "overflow: scroll" or "overflow: auto" directly on Handsontable container. Until now, it worked also when you set overflow scroll/auto on any of the container parents, but that turned out to be not compatible with Twitter Bootstrap
+
+Features added in 0.6.0 (described in [README.md](https://github.com/warpech/jquery-handsontable)):
+  - virtual scrolling that solves problem with row/column header flicker in IE and FF when the grids quickly scrolled
+  - public method `getData` now accepts optional arguments to return only fragment of grid data (e.g. current selection)
+  - new public method `getDataReference` works the same as `getData` but returns data as reference, which is faster but can mess up if manipulated outside the plugin
+
+Bugfixes:
+  - keyword `this` in onChange, onBeforeChange, onSelection callbacks points to container HTML element
+  - editing a field in Firefox 3.6.28 skipped the first character
+  - added default font-family and font-size for .typeahead
+  - TAB does not move cell selection if cell is not being edited (#151)
+  - HTML special chars should be preserved in data map but escaped in DOM (#147)
+  - rowHeaders/colHeaders false should not init row/col headers (#141)
+  - legend icon did not resize column header
+
+## [0.5.1](https://github.com/warpech/jquery-handsontable/tree/v0.5.1) (Sep 7, 2012)
+
+- features (described in [README.md](https://github.com/warpech/jquery-handsontable)):
+  - allow icons in Legends (see [example](http://warpech.github.com/jquery-handsontable/#example2))
+  - new public method `refreshLegend`
+  - new configuration option `outsideClickDeselects`
+  - added data function reference in autocomplete match (`match: function (row, col, data)`)
+- bugfix:
+  - option `fillHandle: 'horizontal'` and `'vertical'` did not work
+
+## [0.5.0](https://github.com/warpech/jquery-handsontable/tree/v0.5.0) (Aug 15, 2012)
+
+- features (described in [README.md](https://github.com/warpech/jquery-handsontable)):
+  - public methods `getDataAtCell`, `setCellReadOnly` - thanks @Dinesh-Ramakrishnan
+  - public methods `getSelected` - thanks @littley!
+  - public methods `getRowHeader`, `getColHeader`, `getCellMeta`
+  - configuration `autoWrapRow`, `autoWrapCol`, `enterBeginsEditing`
+  - now Enter key behaves more like in Excel (see issue #56)
+- code quality:
+  - add `"use strict";` (ECMAScript strict mode) to all components
+  - allow to run in jQuery noConflict mode
+  - namespace was changed from `handsontable` to `Handsontable` to avoid var name conflicts that people were having by accident
+  - now code is divided into components and built with [Grunt](http://weblog.bocoup.com/introducing-grunt/)
+- tests: added four Selenium IDE tests to automate testing of bugfixes. This is a start - more tests will be added in future versions. Tests are located in [test/](https://github.com/warpech/jquery-handsontable/tree/master/test) directory.
+- 75 bugfixes
+
+## [0.4.2](https://github.com/warpech/jquery-handsontable/tree/v0.4.2) (Jun 18, 2012)
+
+- features:
+  - row and column headers (options: `rowHeaders`, `colHeaders`)
+  - public methods `selectCell`, `deselectCell`
+
+## [0.4.1](https://github.com/warpech/jquery-handsontable/tree/v0.4.1) (Jun 15, 2012)
+
+- feature: public methods `setDataAtCell`, `loadData` now have a new parameter `allowHtml` that will omit escaping of HTML code
+
+## [0.4.0](https://github.com/warpech/jquery-handsontable/tree/v0.4.0) (Jun 04, 2012)
+
+- first version number to be documented here
+- feature: undo/redo

+# Contributing to Handsontable
+
+Your contributions to the project are very welcome. If you would like to fix a bug or propose a new feature, you can submit a Pull Request.
+
+To help us merge your Pull Request, please make sure you follow these points:
+
+1. Describe the problem in the Pull Request description (of course you would do it, why do I mention that?)
+2. Please make your fix on a separate branch. This makes merging much easier.
+3. Do not edit files `jquery.handsontable.js`, `jquery.handsontable.css`, `jquery.handsontable.full.js`, `jquery.handsontable.full.css`. Instead, try to edit files inside the `src/` directory and then use `grunt` to make a build. More information about this on wiki page [Building](https://github.com/warpech/jquery-handsontable/wiki/Building).
+4. Very important: For any change that you make, **please try to also add a test case(s)** in `tests/jasmine/spec/` or `src/3rdparty/walkontable/test/jasmine/spec/`. This helps us understand the issue and make sure that it will stay fixed forever.
+
+Thank you for your commitment!

+# Handsontable [![Build Status](https://travis-ci.org/warpech/jquery-handsontable.png?branch=master)](https://travis-ci.org/warpech/jquery-handsontable)
+
+Handsontable is a minimalistic approach to Excel-like table editor in HTML & jQuery. Requires jQuery 1.9+ or 2.0+ (may work with 1.7+ too, but there are known issues with [IE10](https://github.com/warpech/jquery-handsontable/issues/410)).
+
+Runs in IE7, IE8, IE9, IE10, Firefox, Chrome, Safari and Opera.
+
+See the demos at http://handsontable.com/ or fork the example on [JSFiddle](http://jsfiddle.net/warpech/hU6Kz/).
+
+## Usage
+
+First, include all the dependencies. All the files that you need (apart from jQuery) are in the `dist\` directory:
+
+```html
+<script src="../lib/jquery.min.js"></script>
+<script src="dist/jquery.handsontable.full.js"></script>
+<link rel="stylesheet" media="screen" href="dist/jquery.handsontable.full.css">
+```
+
+Then, run `handsontable()` constructor on an empty div. After that, load some data if you wish:
+
+```html
+<div id="dataTable"></div>
+<script>
+  var data = [
+    ["", "Kia", "Nissan", "Toyota", "Honda"],
+    ["2008", 10, 11, 12, 13],
+    ["2009", 20, 11, 14, 13],
+    ["2010", 30, 15, 12, 13]
+  ];
+  $("#dataTable").handsontable({
+    data: data,
+    startRows: 6,
+    startCols: 8
+  });
+</script>
+```

+          <h2>Backbone.js</h2>
+
+          <p>
+            <a href="http://backbonejs.org/">Backbone.js</a> is a client-side
+            MV* framework that can do some pretty smart things
+            with data going to and coming back from a server, and has a great
+            event model for keeping multiple views in sync.
+          </p>
+
+          <p>
+            This little example shows how Backbone Models and Collections can
+            work with Handsontable. Below, you'll see events firing from
+            changes in the <code>CarCollection</code> by Handsontable or
+            otherwise.
+          </p>
+
+          <div id="example1"></div>
+
+          <p>
+            <button name="dump" data-dump="#example1" title="Prints current data source to Firebug/Chrome Dev Tools">
+              Dump data to console
+            </button>
+            <button id="add_car">Simulate a new Car</button>
+
+            <br>
+            <select multiple="multiple" id="example1_events" style="width: 100%; height: 100px"></select>
+          </p>
+
+          <p>
+            <strong>Please note</strong> that Backbone integration is a work in progress since Handsontable 0.8.14.
+            The code presented here has 2 known issues:
+          </p>
+
+          <ul>
+            <li>inserting and removing rows or columns triggers errors, both when using <code>alter</code> method and
+              the context menu
+            </li>
+            <li><code>minSpareRows</code> does not have effect directly after row was added from Backbone (as a
+              workaround, you would need to call <code>loadData</code> instead of <code>render</code>)
+            </li>
+          </ul>
+
+          <p>
+            Both issues will be addressed in future versions of HT. Contributions are welcome!

+      <h2>Object data source (custom data schema)</h2>
+
+      <p>When you use object data binding, Handsontable needs to know the data structure to create when you add a new
+        row.</p>
+
+      <p>If your data source contains at least one row, Handsontable will figure out the data structure based on the
+        first row.</p>
+
+      <p>In case you want to start with an empty data source, you will need to provide the <strong>dataSchema</strong>
+        option that contains the data structure for any new row added to the grid.</p>
+
+      <p>The below example shows custom data schema with an empty data source:</p>

+UNOFFICIAL GITHUB BUTTONS
+=========================
+
+Showcase your GitHub (repo's) success with these three simple, static buttons featuring dynamic watch, fork and follower counts and a link to your GitHub repo or profile page.
+
+To get started, checkout http://ghbtns.com!
+
+
+
+Usage
+-----
+
+These buttons are hosted via GitHub Pages, meaning all you need to do is include an iframe and you're set. Once included, you can configure it with various options. Here's the include:
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=USERNAME&repo=REPONAME&type=BUTTONTYPE"
+  allowtransparency="true" frameborder="0" scrolling="0" width="62" height="20"></iframe>
+```
+
+### Requirements
+
+`user`<br>
+GitHub username that owns the repo<br>
+
+`repo`<br>
+GitHub repository to pull the forks and watchers counts
+
+`type`<br>
+Type of button to show: `watch`, `fork`, or `follow`
+
+### Optional
+
+`count`<br>
+Show the optional watchers or forks count: *none* by default or `true`
+
+`size`<br>
+Optional flag for using a larger button: *none* by default or `large`
+
+
+
+Examples
+--------
+
+**Basic Watch button**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&repo=github-buttons&type=watch"
+  allowtransparency="true" frameborder="0" scrolling="0" width="62" height="20"></iframe>
+```
+
+**Basic Fork button**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&repo=github-buttons&type=fork"
+  allowtransparency="true" frameborder="0" scrolling="0" width="53" height="20"></iframe>
+```
+
+**Basic Follow button**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&type=follow"
+  allowtransparency="true" frameborder="0" scrolling="0" width="132" height="20"></iframe>
+```
+
+**Watch with count**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&repo=github-buttons&type=watch&count=true"
+  allowtransparency="true" frameborder="0" scrolling="0" width="110" height="20"></iframe>
+```
+
+**Fork with count**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&repo=github-buttons&type=fork&count=true"
+  allowtransparency="true" frameborder="0" scrolling="0" width="95" height="20"></iframe>
+```
+
+**Follow with count**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&type=follow&count=true"
+  allowtransparency="true" frameborder="0" scrolling="0" width="165" height="20"></iframe>
+```
+
+**Large Watch button with count**
+
+``` html
+<iframe src="http://ghbtns.com/github-btn.html?user=markdotto&repo=github-buttons&type=watch&count=true&size=large"
+  allowtransparency="true" frameborder="0" scrolling="0" width="170" height="30"></iframe>
+```
+
+Limitations
+-----------
+
+For the first version, functionality is limited and some concessions were made:
+
+- Width and height must be specificed for all buttons (which actually adds some control for those with OCD like myself).
+- All attributes must be passed through via URL parameters.
+- CSS and javascript are all included in the same HTML file to reduce complexity and requests.
+
+**Usage with SSL**
+
+In order to avoid `insecure content` warnings when using GitHub Buttons on a page behind an SSL certificate, simply host a copy of the `github-btn.html` file on your secure directory and substitute your domain in the iframe include: 
+
+``` html
+<iframe src="https://YOURDOMAIN.com/github-btn.html?user=USERNAME&repo=REPONAME&type=BUTTONTYPE"
+  allowtransparency="true" frameborder="0" scrolling="0" width="62" height="20"></iframe>
+```
+
+More refinement and functionalty is planned with open-sourcing--any help is always appreciated!

+# Highlight.js
+
+Highlight.js highlights syntax in code examples on blogs, forums and,
+in fact, on any web page. It's very easy to use because it works
+automatically: finds blocks of code, detects a language, highlights it.
+
+Autodetection can be fine tuned when it fails by itself (see "Heuristics").
+
+
+## Installation and usage
+
+The download package includes the file "highlight.pack.js" which is a full
+compressed version of the library intended for use in production. All
+uncompressed source files are also available, feel free to look into them!
+
+The script is installed by linking to a single file and making a single
+initialization call:
+
+```html
+<script type="text/javascript" src="highlight.pack.js"></script>
+<script type="text/javascript">
+    hljs.initHighlightingOnLoad();
+</script>
+```
+
+Also you can replace TAB ('\x09') characters used for indentation in your code
+with some fixed number of spaces or with a `<span>` to give them special
+styling:
+
+```html
+<script type="text/javascript">
+  hljs.tabReplace = '    '; // 4 spaces
+  // ... or
+  hljs.tabReplace = '<span class="indent">\t</span>';
+
+  hljs.initHighlightingOnLoad();
+</script>
+```
+
+The script looks in your page for fragments `<pre><code>...</code></pre>`
+that are traditionally used to mark up code examples. Their content is
+marked up by logical pieces with defined class names.
+
+
+### Custom initialization
+
+If you use different markup for code blocks you can initialize them manually
+with `highlightBlock(code, tabReplace)` function. It takes a DOM element
+containing the code to highlight and optionally a string with which to replace
+TAB characters.
+
+Initialization using, for example, jQuery might look like this:
+
+```javascript
+$(document).ready(function() {
+  $('pre code').each(function(i, e) {hljs.highlightBlock(e, '    ')});
+});
+```
+
+If your code container relies on `<br>` tags instead of line breaks (i.e. if
+it's not `<pre>`) pass `true` into third parameter of `highlightBlock`:
+
+```javascript
+$('div.code').each(function(i, e) {hljs.highlightBlock(e, null, true)});
+```
+
+### Styling
+
+Elements of code marked up with classes can be styled as desired:
+
+```css
+.comment {
+  color: gray;
+}
+
+.keyword {
+  font-weight: bold;
+}
+
+.python .string {
+  color: blue;
+}
+
+.html .atribute .value {
+  color: green;
+}
+```
+
+Highlight.js comes with several style themes located in "styles" directory that
+can be used directly or as a base for your own experiments.
+
+**Note**: provided styles work for code defined inside `<pre>` blocks. If you use
+custom markup you should modify styles accordingly.
+
+For full reference list of classes see [classref.txt][cr].
+
+[cr]: http://github.com/isagalaev/highlight.js/blob/master/classref.txt
+
+
+## Export
+
+File export.html contains a little program that allows you to paste in a code
+snippet and then copy and paste the resulting HTML code generated by the
+highlighter. This is useful in situations when you can't use the script itself
+on a site.
+
+
+## Heuristics
+
+Autodetection of a code's language is done using a simple heuristic:
+the program tries to highlight a fragment with all available languages and
+counts all syntactic structures that it finds along the way. The language
+with greatest count wins.
+
+This means that in short fragments the probability of an error is high
+(and it really happens sometimes). In this cases you can set the fragment's
+language explicitly by assigning a class to the `<code>` element:
+
+```html
+<pre><code class="html">...</code></pre>
+```
+
+You can use class names recommended in HTML5: "language-html",
+"language-php". Classes also can be assigned to the `<pre>` element.
+
+To disable highlighting of a fragment altogether use "no-highlight" class:
+
+```html
+<pre><code class="no-highlight">...</code></pre>
+```

+
+          <h2>Numeric cell type</h2>
+
+          <p>By default, Handsontable treats all cell values as <code>string</code> type. This is because <code>&lt;textarea&gt;</code>
+            returns a string as its value.</p>
+
+          <p>In many cases you will prefer cell values to be treated as <code>number</code> type. This allows to format
+            numbers nicely and sort them correctly.</p>
+
+          <p>To trigger the Numeric cell type, use the option <code>type: 'numeric'</code> in <code>columns</code> array
+            or
+            <code>cells</code> function.</p>
+
+          <p>Numeric cell type uses <a href="http://numeraljs.com/">Numeral.js</a> as the formatting library. Head over
+            to
+            their website to learn about the formatting syntax.</p>
+
+          <p>To use number formatting style valid for your language (i18n), load language definition to Numeral.js. See
+            "Languages" section in <a href="http://numeraljs.com/">Numeral.js docs</a> for more info.</p>

+            available in Handsontable:</p>
+

+            <li><a href="autocomplete.html">autocomplete</a></li>
+          </ul>
+
+          <p>The same example also shows the declaration of custom cell renderers, namely <code>yellowRenderer</code>
+            and

+          <h2>Anatomy of a cell type</h2>
+
+          <p>A cell type is a predefined set of cell properties. Cell type defines what <strong>renderer</strong>
+            and <strong>editor</strong> should be used for a cell. They can also define any different cell property that
+            will be assumed for each matching cell.</p>
+
+          <p>For example writing:</p>
+
+        <pre class="javascript"><code>
+        columns: [
+          {
+            type: 'text'
+          }
+        ]
+        </code></pre>
+
+          <p>Equals:</p>
+
+        <pre class="javascript"><code>
+        columns: [
+          {
+            renderer: Handsontable.TextRenderer,
+            editor: Handsontable.TextEditor
+          }
+        ]
+        </code></pre>

+
+      <p>This page shows our effort to make a <a href="">Web Component</a>-compatible version of Handsontable.</p>
+
+      <p>Our Web Component implementation leverages <a
+        href="https://github.com/toolkitchen/toolkit">Toolkitchen Toolkit</a> library. Currently, it works correctly
+        only in Google Chrome. According to the <a
+          href="http://toolkitchen.github.io/compatibility.html">browser compatibility matrix</a>, it should also
+        be possible to run it in Firefox, IE10, Safari (though right now it produces <em>Assertion failed</em> error
+        in every browser except Chrome).
+      </p>
+
+      <p>All your help (review, comments, pull requests) in this area is very welcome. Please use the GitHub Issues
+        <a
+          href="https://github.com/warpech/jquery-handsontable/issues/603">ticket #603</a> to share your

+# Handsontable distributions
+
+## Full distribution (recommended)
+
+The full distribution allows you to use Handsontable by just including jQuery and 2 files:
+```html
+<script src="lib/jquery.min.js"></script>
+<script src="dist/jquery.handsontable.full.js"></script>
+<link rel="stylesheet" media="screen" href="dist/jquery.handsontable.full.css">
+```
+
+**jquery.handsontable.full.js** and **jquery.handsontable.full.css** are compiled with ___all___ the needed dependencies.
+
+Using this has the same effect as loading all the dependencies from the Bare distribution (see below).
+
+## Bare distribution
+
+If you are a "Bob the Builder" kind of hacker, you will need to load Handsontable JS, CSS and their dependecies:
+```html
+<script src="lib/jquery.min.js"></script>
+<script src="dist/jquery.handsontable.js"></script>
+<script src="lib/bootstrap-typeahead.js"></script>
+<script src="lib/jQuery-contextMenu/jquery.contextMenu.js"></script>
+<script src="lib/jQuery-contextMenu/jquery.ui.position.js"></script>
+<link rel="stylesheet" media="screen" href="dist/jquery.handsontable.css">
+<link rel="stylesheet" media="screen" href="lib/jQuery-contextMenu/jquery.contextMenu.css">
+```
+
+**jquery.handsontable.js** and **jquery.handsontable.css** are compiled ___without___ the needed dependencies.

+# Handsontable Web Components distribution
+
+As a future alternative to jQuery, we are experimenting with Web Components version of Handsontable (see <a href="http://handsontable.com/demo/web_component.html">demo page</a> for more details).
+
+To use the current experimental version, just load the Toolkitchen Toolkit library and import `x-handsontable.html` component.
+
+```html
+<!-- 1. Load Toolkitchen Toolkit library -->
+<script src="toolkit/platform/platform.js"></script>
+<!-- 2. Load the component -->
+<link rel="import" href="../dist_wc/x-handsontable.html">
+<!-- 3. Load a Numeral.js locale if you use numeric cell type -->
+<script src="../lib/numeral.de-de.js"></script>
+```

+# Walkontable
+
+This is a playground for next table view engine that will enable virtual rendering in [Handsontable](http://handsontable.com/).
+
+Works in IE7+, FF3.6+, latest Opera, Safari and Chrome.
+
+Built with almost full TDD test coverage (Jasmine).
+
+## Bugs
+
+This code was created with the intention to be used as part of Handsontable and will only be supported by the author
+when used in that way. This may change in future. Thanks for understanding.
+
+## Design considerations
