Changelog

0.13

==============

.. warning:: This release contains breaking changers, please read the notes below

.. rubric:: Dropped support for Python versions that reached their end-of-life.

Bottle up to 0.12 supported an absurd range of Python versions (2.5 to 3.12) and
keeping support for Python versions as ancient as 2.5 required a ton of workarounds
and compromises, but served no real purpose. If you need support for older Python
versions, you can stay on bottle 0.12. The updated list of tested and supported python
releases is as follows:

* Python 2 >= 2.7.3
* Python 3 >= 3.8

Support for Python 2.5 was marked as deprecated since 0.12. We decided to go a step further
and also remove support for 2.6 and 3.1 to 3.7 even if it was never deprecated explicitly
in bottle. This means that this release is *not* backwards compatible in Python <2.7.3 or

0.12.25

* Read the release notes for the next minor release, run your tests and fix all
deprecation warnings.
* Upgrade to the next minor release (e.g. ``0.12.25`` to ``0.13.2``), run test
again, fix all warnings and continue.

.. rubric:: Support for old releases

Bugs and security issues are usually fixed in the latest minor release of the
two most recent major releases (named stable and old-stable). With each new major
release, stable becomes old-stable and the old old-stable will no longer receive
regular updates. LTS releases (e.g. 0.12) are an exception. Those will continue
to receive updates on a best-effort basis.
