Version 1.5.4

• Store maxx and maxy used to create a given preview for cases where we need to regenerate it (PUT).
• No longer allow manage_http_upload to regenerate previews.
• Don't break getIconPath if the content_type is malformed or empty.
• Added a NORMALIZE_CASE repository option that lowercases directory names. This makes for prettier static URLs and aids cross-filesystem portability of the repository.
• Added a CUSTOM repository option that determines the directory structure by calling a user-defined CUSTOM_METHOD. Thanks to Markus Krainer.
• 260+ unit tests.

Version 1.5.2

• Support OFS.Cacheable API to work with HTTP cache managers.
• Return a stream iterator instead of writing to the RESPONSE. This speeds up ExtFile/ExtImage serving significantly, making it faster than the standard File and Image.
• Filename-to-id translation now supports utf-8 in addition to latin-1.
• 240+ unit tests

Version 1.5.0

• Made sure 304 responses return a RFC1123 date.
• 200+ unit tests.

Version 1.5.0-beta1

• No longer use an acquired REQUEST in ExtFile.index_html().
• No longer mangle extensions of unknown binary files.
• Switched to Zope 2.8 transactions and an all new TM strategy.
• Fixed a bug in manage_upload() which didn't have tests.
• Factory methods now return the id.
• Renamed icon_html to icon_tag, preview_html to preview_tag.
• Implemented PrincipiaSearchSource for text/* files.
• Counter in file names now separated from name by a dot.
• Colon, single- and double-quote added to bad_chars list.
• Fixed tag() method to use icon url if there is no preview.
• 190+ unit tests.

Version 1.4.4

• Fixed missing import of TemporaryFile.
• Fixed support for the Photo product which was broken in 1.4.2. Note that you cannot use ZODB_PATH = PHYSICAL with Photos!
• Images using the CMYK color model are converted to RGB before computing the preview. Thanks to Jan-Wijbrand Kolman.
• 130+ unit tests.

Version 1.4.2

• Fixed an RFC violation. See http://collector.zope.org/Zope/544.
• Fixed "no context" detection for Zope 2.7.
• Fixed repository umask for generated previews.
• Stopped _createPreview() from swallowing PIL exceptions.
• SYNC_ZODB can now use the physical path (see Config.py).
• Bundled Bjorn Nelson's extFile_load_site.sh utility, that can be used to bulk upload data into ExtFiles/ExtImages.
• 120 unit tests.

Version 1.4.0

• ExtFile and ExtImage now have interfaces properly declared.
• ExtFile and ExtImage are now transaction-aware. File operations are performed using temporary files, which are "committed" (or removed) at the end of the transaction. This makes sure repository files are only created/modified if the transaction completes successfully.
• 100+ unit tests.

This release was sponsored by Infrae and ETH Zürich. The initial implementation came from Christian Zagrodnick of gocept. Thanks for making this possible.
