http://plone.org/products/plone.app.blob/issues/11
[j23d, rossp, witsch]

- Fix image field validator to match that from `ATContentTypes`.
[rossp]

- With `ATContentTypes` >=2.0, check the `_should_set_id_to_filename`
method to determine if `ATBlob`'s `fixAutoId` method should set the
item id to the filename of the blob field. For images, don't set it
to the filename if a title was supplied.
[davisagli]

- Add blobbable adapters for Python file objects and OFS Pdata objects.
[davisagli]

- Add helper view to get a rough estimate of the total size of binary
content in a site.
[witsch]

------------------

- Fix regression in setup for running bbb tests against Plone 3.x.

been quick-installed yet. Fixes http://dev.plone.org/plone/ticket/8496
[witsch]

- Preserve filename when editing via WebDAV. This fixes
http://plone.org/products/plone.app.blob/issues/23

replacement types using the "cmf_edit" method.
[alecm]

[ggozad, witsch]

- Refactor test setup to make it work with ZODB 3.9.
[witsch]

------------------

- Minor fixes and test updates for compatibility with Plone 4.0.
[witsch]

- Store image scales in blobs.
[witsch]

- Use correct permissions when registering replacement types for
"File" and "Image" content.
See http://plone.org/products/plone.app.blob/issues/9

- Fix migration issue regarding stale catalog index- & meta-data.
[witsch]

[witsch]

------------------

- Fix compatibility issue with `repoze.zope2`.
[optilude, witsch]

- Fix compatibility issues with ZODB 3.9 and Plone 4.0.
[witsch]

- Speed up migration of existing content by using "in-place" migrators
and avoid unnecessary re-indexing.
[witsch]

- Fix registration of blob-based image scale adapter to prevent getting
404s for content other than images. This fixes the second issue
related to http://plone.org/products/plone.app.blob/issues/19
[witsch]

------------------

- Provide maintenance view for (re)setting blob sub-types, which can also
be used to fix things after upgrading from 1.0b2 or earlier.
This fixes http://plone.org/products/plone.app.blob/issues/19
[witsch]

------------------

- Clean up GenericSetup profiles to allow separate installation of
replacement types for "File" and "Image" content.
[witsch]

- Add index accessor to make indexing of file content work again.
This fixes http://plone.org/products/plone.app.blob/issues/12
[witsch]

- Make code more robust in case of missing blob files.
This fixes http://plone.org/products/plone.app.blob/issues/10
[witsch]

- Make tests clean up their temporary blob directories.
[stefan]

- Remove quota argument from DemoStorage calls.
[stefan]

- Add workaround to prevent breakage with CMFEditions (blob-based
content can still not be versioned, though).
[witsch]

- Add missing acquisition-wrapper, also allowing to remove circular
references between instance and field, which broke pickling.
[witsch]

- Fix helper for determining image sizes to not break for non-image
content.
[witsch]

- Use PIL for determining image sizes as the OFS code cannot handle
certain types of JPEGs.
[witsch]

- Added missing metadata.xml to the default profile.
[hannosch]

- Only use the file name for id generation for the replacement types,
i.e. "File" and "Image", but not custom types. This fixes
http://plone.org/products/plone.app.blob/issues/3
[witsch]

- Fix issue where the mime-type registry returned an empty tuple when
looking up an unknown mime-type. This fixes
http://plone.org/products/plone.app.blob/issues/1
