0.6.2

• Updated Circle CI configuration and switch to that for OS X builds (instead of Travis CI)
• Documentation updates: PyRegion
• IWYU documentation update
• Fixed C++ boolean ref counting bug that caused segfaults when running Python projects
• Update pytest and pycapnp dependency versions
• Implemented byte buffer passing as alternative Python<->C++ strategy for capnp serialization logic. This has some memory/speed overhead but avoids ABI issues that could cause crashes
• Fixed prototest to get meaningful comparison numbers

0.6.1

• Eliminate installation of unnecessary header files when building nupic.bindings. Install Version.hpp unconditionally for the sake of the deployment usage in .travis.yaml
• Fixed servicing of delayed links such that the circular buffers of all links within a network are refreshed at the end of each time step; and 0-delay links copy data directly from src to dest, bypassing the circular buffer altogether.
• Add a nNonZerosPerRowOnCols SparseMatrix method
• Fix up some out of date SWIG interface code

0.6.0

• NUP-2366 Remove no-longer-relevent test code
• NUP-2366 Do not pass arguments in initialize, remove conflicting docstring
• Add a unit test for mapSegmentsToCells
• Change segments to UInt32 to speed up the bindings
• Fix up fetch_remote script to properly poll until the build is complete.
• Updates to tests moved over from nupic
• removed shebangs
• Changed all copyright headers on all files to AGPL.
• Tests folder refactored
• Reads version from VERSION for doc output
• Fixing travis-ci unit tests
• Doxygen only creates XML, used by Breathe to create docs.

0.5.3

• Added comment explaining the nuance of the static variables in Cells4::adaptSegment
• Improved explanation of containers in Cells4::adaptSegment implementation.
• Regenerate SWIG bindings C++ files if any headers change.
• Enable -D_LIBCPP_DEBUG=0 for debug-lite in Clang builds (e.g., OS X). NOTE: Clan't debug mode is not mature, and anything above level 0 appears to require de
  bug build of libc++ during linking, which it not present by default on OS X.* Fixed deletion of wrong synapses and index-out-of-bounds in Cells4::adaptSegment/Segment::freeNSynapses.
• corrected typo in CHANGELOG.md (boostingStrength -> boostStrength)
• Remove ExtendedTemporalMemory proto
• Fix bug in unit test, make TM catch this bug in DEBUG builds
• Perf: Densify prevActiveCells rather than binary searching
• Get POC of OS X build on circle.ci up and running.
• Bump version to prerelease.

0.5.1

• Improved network API introspection
• Fix bug with region dimensions inference in network API. fixes #1212
• Updates to info in RELEASE.md
• Fixup import favoring native unittest
• Use xcode6.4 image per documentation at https://docs.travis-ci.com/user/osx-ci-environment/#OS-X-Version
• NUP-2316 Fixed OS X build failure on xcode 8 caused by included some files in static library that shouldn't have been included.
• Misc. changes for sparse matrices and using them in Connections. Moving loops to C++.

0.5.0

• Link: Implemented delayed links. NOTE: this is not backwards compatible with CLAModel class, so Nupic will be updated as well.
• SparseMatrix: Stop copying input vectors
• Drop the declare_namespace call - Issue #1072
• SparseMatrix: Add option to specify rows in nNonZerosPerRow
• SparseMatrix: setRandomZerosOnOuter with list of counts
• SparseMatrix: rightVecSumAtNZ cleanup
• SparseMatrix: Put cols in dense array even when not necessary
• Removes experimental code that will now live in nupic.research.core.
• Removed unused, obsolete NetworkFactory class.

0.4.16

• SpatialPooler: Stop rounding the boost factors
• SpatialPooler: Rename "maxBoost" to "boostingStrength"
• SpatialPooler: Remove minActiveDutyCycles and minPctActiveDutyCycles

0.4.15

• SpatialPooler: Tweak the boost factor rounding to mimic numpy's rounding of float32s

0.4.14

• SpatialPooler: New boosting algorithm
• SpatialPooler: Stop putting tie-break info into the overlaps. getBoostedOverlaps() return values are now more correct.
• SpatialPooler: Use an EPSILON when comparing permanences to a threshold to avoid floating point differences.
• SpatialPooler: Round the boost factors to two decimal places to avoid floating point differences.

0.4.13

• Use VERSION file when generating docs.
• 64-bit gcc on Windows build error
• New: setZerosOnOuter, increaseRowNonZeroCountsOnOuterTo
• Remove a nupic.math test that should stay in nupic
• Use unittest, not unittest2, to match the nupic.core CI config
• Add C++ unit tests for the new SparseMatrix methods
• Finish moving nupic.bindings math tests to nupic.core
• s/AboveAndBelow/BelowAndAbove
• Moves some tests for SWIG bindings from nupic to nupic.core
• Better method names: s/AboveAndBelow/BelowAndAbove
• Four new SparseMatrix methods, enabling batch synapse learning
• Expose the nrows,ncols SparseBinaryMatrix ctor in the bindings
