Plone.app.layout

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

- Adjust the caching of sitemap.xml.gz. We only cache for anonymous users. That
fixes a bug where a cached sitemap.xml.gz is delivered with information that
only an user with more privilegs is allowed to see. We also make sure that
the cached file was build with a current catalog by adding the catalog
counter to the cache key. Based on a patch by stxnext. Fixes
http://dev.plone.org/plone/ticket/8402
[stxnext, csenger]

- Added time_only for use with toLocalizedTime so that event_view now localizes
the start/end times if the start/end dates are the same. Closes
http://dev.plone.org/plone/ticket/8607
[jnelson, calvinhp]

- Fixed Plone 3.1 backward compatibility of above.
[stefan]

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

- Modified user profile item on the dashboard to use an image tag
instead of a background image. This makes it more consistent with
the other list items and easier to style for RTL scripts.
[emanlove]

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

- Avoid a test failure caused by test interdependencies.
[hannosch]

- Fixed tests for the language method of the portal state view.
[hannosch]

- Fixed keywords.pt to properly encode ampersands in its links. This closes
http://dev.plone.org/plone/ticket/8509
[younga3, dunlapm]

- Fixed site_icon so that we would have flipped icon in case of RTL.
This closes http://dev.plone.org/plone/ticket/4576
[spliter]

- Fixed generation of links to author.cpt for user IDs that are a URL
(OpenID users, e.g.). This closes http://dev.plone.org/plone/ticket/8040
[davisagli]

- Add some tests on private contents for sitemap.xml.gz generation. This
closes http://dev.plone.org/plone/ticket/8402
[encolpe]

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

- Fixed an invalid message id for the dashboard. This closes
http://dev.plone.org/plone/ticket/7758.
[hannosch]

- Fixed comments.pt to pass the title of the comment you are replying to into
the discussion_reply_form. This closes
http://dev.plone.org/plone/ticket/8323
[calvinhp]

- Refactor default_page: move all logic out of the view to separate methods
so they can be called without a request (which is not used at all).
Deprecate parameters which were not in the interface and were never used.
[wichert]

- Added note that Javascript is required for presentation mode. This closes
http://dev.plone.org/plone/ticket/7575 and
http://dev.plone.org/plone/ticket/7573
[limi]

- Fixed plone_context_state's view_url method to work with contexts that don't
have a portal_type. This closes http://dev.plone.org/plone/ticket/8028.
[davisagli]

- Changed IContentIcon to expose users to the title of the FTI instead of the
portal_type. This closes http://dev.plone.org/plone/ticket/8246.
[hannosch]

- Adjusted deprecation warnings to point to Plone 4.0 instead of Plone 3.5
since we changed the version numbering again.
[hannosch]

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

- Made PersonalBarViewlet tolerate users who don't have a Plone user object, as
when using OpenID or apachepas. This fixes
http://dev.plone.org/plone/ticket/7296.
[erikrose]

- Use 'index' attribute rather than 'render' for setting viewlet templates, so
that they can be overridden using the 'template' ZCML attribute.
[davisagli]

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

- Applied patch from http://dev.plone.org/plone/ticket/7942 to ensure that the
'currentParent' marker is not True for items that have a path that is a
substring of the true path.
[optilude]

- Displaying 'Anonymous User' also when the comment creator is an empty
string. This fixes http://dev.plone.org/plone/ticket/7712.
[rsantos]

- Allow the use of the icon attribute on action directly instead of using the
actionicons tool.
[hannosch]

- Fix invalid leading space in all 'Up to Site Setup' links.
[wichert]

- Fixed permission in workflow history viewlet. This closes
http://dev.plone.org/plone/ticket/5507.
[hannosch]

- Made handling of self.context in portal.py consistent.
[hannosch]

- Rename the portal_url instance variable to site_url in the ViewletBase
class. This prevents getToolByName(..., 'portal_url') from returning
the URL string instead of the portal_url tool, which can causes unexpected
and subtle breakage. portal_url is still available but produces a deprecation
warning. It will be removed in Plone 4.
[wichert]

- Added viewlet for RSS link.
[fschulze]

- Added dependency on plone.app.viewletmanager.
[fschulze]

- Make viewlet managers in head section order- and filterable.
