=========================== Release Notes and Changelog

Release 0.13

.. warning:: Not released yet.

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

Keeping up support for ancient Python versions hinders adaptation of new features and serves 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 2.7 (>= 2.7.3)
• Python 3.6
• Python 3.7
• Python 3.8
• Python 3.9
• PyPy 2.7
• PyPy 3.6
• PyPy 3.7

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 3.5 even if it was never deprecated explicitly in bottle. This means that this release is not backwards compatible in Python <2.7.3 or <3.6 environments. Maintainers for distributions or systems that still use these old python versions should not update to Bottle 0.13 and stick with 0.12 instead.

.. rubric:: Stabilized APIs

• The documented API of the :class:ConfigDict class is now considered stable and ready to use.

.. rubric:: Deprecated APIs

• The old route syntax (/hello/:name) is deprecated in favor of the more readable and flexible /hello/<name> syntax.
• :meth:Bottle.mount now recognizes Bottle instance and will warn about parameters that are not compatible with the new mounting behavior. The old behavior (mount applications as WSGI callable) still works and is used as a fallback automatically.
• The undocumented :func:local_property helper is now deprecated.
• The server adapter for google app engine is not useful anymore and marked as deprecated.
• Bottle uses pickle to store arbitrary objects into signed cookies. This is safe, as long as the signature key remains a secret. Unfortunately, people tend to push code with signature keys to github all the time, so we decided to remove pickle-support from bottle. Signed cookies will now issue a deprecation warning if the value is not a string, and support for non-string values will be removed in 0.14. The global :func:cookie_encode, :func:cookie_decode and :func:is_cookie_encoded are now also deprecated. If you are using this feature, think about using json to serialize your objects before storing them into cookies, or switch to a session system that stores data server-side instead of client-side.

.. rubric:: Removed APIs (deprecated since 0.12)

• Plugins with the old API (api=1 or no api attribute) will no longer work.

• Parameter order of :meth:Bottle.mount changed in 0.10. The old order will now result in an error instead of a warning.

• The :class:ConfigDict class was introduced in 0.11 and changed during 0.12. These changes are now final.

  • Attribute access and assignment was removed due to high overhead and limited usability.
