- Fixed a bug (#2560) - :doc:`Form Helper <helpers/form_helper>` function :php:func:`form_open()` set the 'method="post"' attribute only if the passed attributes equaled an empty string.
- Fixed a bug (#2585) - :doc:`Query Builder <database/query_builder>` methods ``min()``, ``max()``, ``avg()``, ``sum()`` didn't escape field names.
- Fixed an edge case (#2583) in the :doc:`Email Library <libraries/email>` where `Suhosin <http://www.hardened-php.net/suhosin/>` blocked messages sent via ``mail()`` due to trailing newspaces in headers.
+- Fixed a bug (#2590) - :php:func:`log_message()` didn't actually cache the ``CI_Log`` class instance.
