Release Notes: Support for switchable x86/x86_64 Cygwin architectures was added. Package lists can now include architectural switches (e.g. to packages not supported on x86_64). The GUI was neatened to include 'folder' icons in place of 'browse' buttons.
Release Notes: Support for multi-byte (UTF-8) characters within package listings was improved.
Release Notes: Commonly used functions have been converted to image buttons on the GUI. The default URL of the Cygwin installer has been updated.
Release Notes: Usability as a Python add-on module was improved. An example automatic download and update script was added. Handling of source-only Cygwin packages (e.g., boost, pixman) was improved.
Release Notes: Facilities for re-attempting failed downloads were added. Experimental support was added for automatic creation of ISO images. Error reporting of empty packages was improved.
