  • Fixed a bug (#697) - A wrong array key was used in the Upload library to check for mime-types.
  • Fixed a bug - form_open() compared $action against site_url() instead of base_url()
  • Fixed a bug - CI_Upload::_file_mime_type() could've failed if mime_content_type() is used for the detection and returns FALSE.
    • +
  • Fixed a bug (#538) - Windows paths were ignored when using the Image Manipulation Class to create a new file.

Subject: added query grouping to Active Record

this is a feature that has been lacking for a very long time. lots of people complained
about it over the years, but it never got added so you'd have to resort to handcrafted
queries when you needed this feature.

This is a port of code from DataMapper, in use since CI 1.6.

Subject: Turn "pconnect" off by default. Some users were complaining this was
 effecting their performance and having it on by default can potentially cause

 form_open() function will automatically insert a hidden csrf field in
 your forms.
 
+Tokens may be either regenerated on every submission (default) or kept the same throughout the life of the CSRF cookie. The default regeneration of tokens provides stricter security but may result in usability concerns as other tokens become invalid (back/forward navigation, multiple tabs/windows, asynchronous actions, etc). You may alter this behavior by editing the following config parameter::

 Select URIs can be whitelisted from csrf protection (for example API
 endpoints expecting externally POSTed content). You can add these URIs
 by editing the 'csrf_exclude_uris' config parameter::

 	 -  Added support for 3-length hex color values for wm_font_color and wm_shadow_color properties, as well as validation for them.
 	 -  Class properties wm_font_color, wm_shadow_color and wm_use_drop_shadow are now protected, to avoid breaking the text_watermark() method

+	 -  If property maintain_ratio is set to TRUE, image_reproportion() now doesn't need both width and height to be specified.
    -  Minor speed optimizations and method & property visibility declarations in the Calendar Library.
    -  Removed SHA1 function in the :doc:`Encryption Library `.
    -  Added $config['csrf_regeneration'] to the CSRF protection in the :doc:`Security library `, which makes token regeneration optional.
