Disable number-of-wrapped-lines cache. There's a very common crash in OffsetOfWrappedLine starting in beta 6. This is the likely culprit. Issue 5980

Disable ligatures-across-different-backgrounds when muting is in use (cursor boost and dimming use this). A background color is needed to compute the dimmed value.

Fix a bug where numberOfEquivalentRows was always 0 when minimum contrast is 0, which caused text to have the wrong foreground color.

Issue 5961

Fix a bug where the cursor type buttons all had tag 0 so you couldn't change cursor type. Issue 5957

Gray out non-selected tabs when colored tabs are present. Also make the outline black-white-black or white-black-white. Trying to improve visibility of selected tab.

Make tab labels black and white when any tab has color. Make the outline always stark white (with very dark tabs it ended up the same color as the tab bar lines). Make uncolored tabs have a white outline.

Fix a bug in stringByTrimmingTrailingCharactersFromCharacterSet:, where it should have removed everything when all the characters in the string belonged to the set.

Issue 5950

Restore currentTerminal, accidentally removed in 78cba9be. Issue 5959

Get rid of the ugly gradients used with colored tabs. Draw a light outline around the selected tab if any tab has a color. Issue 5799.

searching all sessions with current selections for the one whose selection
was created most recently. This way even if the selection is emoved, you
can still paste it. Brought up in email, subject line "Keep selected text
in buffer until I select another text (like Mac terminal does)".

Improvements for services. Only validate services that don't expect us to send data, unless we have a selection. If we do have a selection, it must take plain text as input. likewise, the service must produce no or plain text output. If it does produce output, call insertText: with it.

Issue 5942

When you perform a new search, begin the query one character in front of the find cursor. That way if the new query should match at the same starting point as the currently highlighted result, it will simply extend it. I think I broke this because it only worked by accident before and I made SearchResults make sense recently. Issue 5949

Allow more services (those that do not produce input and those that accept input) to appear in the services menu. Issue 5942

Fix a bug in regex search where a regex like xa* would return multiple search results against a document like xaaaa (xa, xaa, etc.). Now that search results are properly sorted, this causes strange behavior. For example, only part of a match might be selected. Now, we ignore results that are a subset of a previous result. This works because the search progressively shortens and re-searches the document (e.g., xaaa, xaa, xa, x). Issue 5937

Fix a bug where coords and content would not be in 1:1 correspondence when an url action is found and hard newlines are ignored (set by an advanced pref, which is not the default setting). Remove the corresponding coords as well as the newlines from the string. Issue 5929.

Fix a bug where triggers would highlight lookahead matches. Only the first range needs to be highlighted. That's the range of the string that matched the pattern. Additional ranges correspond to captures, not all of which are necessarily contained in the first range. Lookaheads fall outside the matched range and should not be highlihgted. Issue 5934.

Fix a bug where the newline policy kiTermTextExtractorNullPolicyFromLastToEnd would include a leading newline after removing text prior to a null. This caused URL actions to detect a region that began one cell early. That null policy is only used in URL action detection.

Issue 5929

Change how adjacent sessions are found. The previous algorithm could loop forever if things weren't laid out correctly, and I think there are subtle bugs in how the split views' subviews get laid out.
Issue 5932

Add new thin strokes settings to enable it with light backgrounds. People who had Always or Retina are migrated to With Dark Backgrounds or Retina and Dark Backgrounds, respectively. Issue 5910.

Make the app hotkey remember the previously active app so it can switch back to it from a lion fullscreen window. Issue 5925.

Respect changes to the preferred screen of a profile with an existing hotkey window. Update the window controller's copy of the preferred screen setting. Only hotkey windows are affected since other kinds of windows do not move from screen to screen after their initial creation. Issue 5923.
