Detailed changelog for Adblock Plus 1.1

The following lists the major changes compared to Adblock Plus 1.0.2:

Known issues

Thunderbird: When clicking "Subscribe" in the subscription list on first run, the entire Thunderbird window is closed. This should be fixed in Thunderbird soon (bug 503299).
SeaMonkey: Toolbar icon looks ugly with the Modern theme. Modern theme doesn't seem to consider the possibility of extensions, using it with Adblock Plus isn't recommended.
Some translations contain untranslated English strings.

Added handling of HTTP redirects, the redirect address now shows up in the list of blockable items as well as the original address, both can be blocked.
Added support for flexible anchors at start of filter (forum topic).
Added support for ^ character that will match a single separator character or end of address (forum topic).
Added support for domain exceptions in element hiding analogous to the $domain option of regular filters, e.g. "example.com,~foo.example.com##foo" or "~example.com##foo" (forum topic).

"Block" button on plug-ins (e.g. Flash or Java) is no longer shown permanently, it only shows up when the mouse is on the plug-in area.
Added "Re-enable Adblock Plus on this page" context menu item for pages where Adblock Plus is disabled, this removes/disables the filter responsible.
Browser integration code runs in its own context now, this makes conflicts with other extensions less likely.
Changed the way "add subscription" links work, these can now only be triggered by user clicking a link.
Added diagnostic page displaying all errors related to Adblock Plus as well as Adblock Plus version/source code revision, can be opened by typing chrome://adblockplus/content/errors.html into the location bar.
Fixed: ABP icon updates its status every two seconds, hogs CPU time.
Fixed: Detection of background images breaks the context menu.
Fixed: "Disable on ..." doesn't work correctly if the exception rule already exists but is disabled.
Fixed: "Disable on ..." doesn't work correctly with rules that already exist in filter subscriptions rather than user-defined filters.
Fixed: Input focus issues when closing list of blockable items in current Firefox nightly builds.

Added "document source" column, hidden by default (domain name to be used for the $domain filter option, forum topic).
Added "Disable this filter on example.com" context menu item for user-defined filters (adds $domain option as required).
Fixed: Creating a filter for an item matching a disabled exception rule wasn't possible again (forum topic).

"Slow filter" warning is now a separate list column which can be used for sorting.
Using browser's real find bar now instead of faking it.
"Close" button moved to the right side of the filter editor, made the button use Firefox 3 look.
Improved position calculations for the filter editor, no longer makes the text position change.
Fixed: Enabling/disabling many element hiding rules at once is slow.
When a list of filters is pasted or imported, always insert comments before the filter that follows them (forum topic, forum topic).
Fixed: Adding a filter subscription that redirects to a different address causes download failure.
Fixed: Same filter might appear twice in the list in a particular scenario.
Fixed: Wrong row is selected when the window is opened (worked around bug 489881).

Added flexible anchors as an option — "at the beginning of domain name" (forum topic).
Added "example.com^" as fourth suggestion, block the entire domain (forum topic).
Added warning when adding a filter to a disabled filter group (forum topic).

Dropped compatibility with old application versions and cleaned up code, now requiring at least: Firefox 3.0.9, SeaMonkey 2.0b1, Thunderbird 3.0b3, Songbird 1.2, Prism 1.0b1.
Moved almost all application-specific code to the overlay file corresponding with that application, this should make application-specific changes easier in future.
Fixed: Toolbar icon cannot be moved to a different location (SeaMonkey).
Fixed: Toolbar icon might be added in one window but not another on first start (SeaMonkey and Thunderbird).
Fixed: Indentation of some menu items of the toolbar icon's menu too large (Songbird).
Fixed: Adblock Plus initialization fails (Prism).

Added explicit support for blocking fonts (@font-type CSS directive in Firefox 3.5).
Clearing browsing history in Firefox now clears hit statistics in Adblock Plus as well (this can be disabled with the hidden extensions.adblockplus.clearStatsOnHistoryPurge preference, forum topic).
Cleaned up data management code, made sure Adblock Plus doesn't use up more memory than necessary.
Fixed: Webpages can easily detect "Collapse blocked elements" option.
Fixed: An error is reported to console on first run (patterns.ini not found).
Fixed: Domain-restricted filters were applied to pages opened from disk.
