Fixed Try/Catch/Else/Finally not executing Finally if Else returns.
Fixed execution of if-else-if-else-if containing fat arrow functions.

Fixed hook hotkeys not recognizing modifiers which are pressed down by SendInput.
Fixed A_AhkPath to not be reliant on the case/format of the command line used to launch the process.
Fixed heap corruption during window searches involving groups. (Broken by v2.0.6)
Launcher:
Fixed #Requires not being detected if followed by a comment other than ; prefer xxx. (Broken by v2.0.6)
Fixed syntax detection misinterpreting multi-line auto-replace hotstrings.
Window Spy:
Changed font to Segoe UI size 9, consistent with Dash.

Fixed some ambiguity with COM calls, such as x.y acting as x.y().
Fixed breakpoint on control flow statement being "hit" when a fat arrow function on the line below it returns.
Fixed Default : to not merge with the line below it. This prevented Default : from being used at the end of a Switch block, and caused any subsequent line to take the line number of the Default.
Optimized ProcessGetPath, ProcessSetPriority and ProcessClose to not scan through all processes when given a valid PID, even if access to the process is denied.
Fixed inability of LWin::Alt to be used to activate some Alt key combos.
Fixed TypeError thrown by x is y to say "Class" rather than "Object".
Fixed WinTitle to support criteria longer than 1023 characters.
Fixed issues when &ref is used on different aliases of the same variable.
Fixed optional parameter default expressions (other than simple literal values) preventing the use of assume-global/assume-static.

Changed the Reload button on error/warning dialogs to explicitly close the dialog, even if the current script instance isn't terminated.
Removed an optimization for return var which caused the variable to appear blank when accessed within a finally block.
Fixed Default (Switch) to allow space before the colon.
Fixed Array.Prototype.RemoveAt to return the removed value when Length is "explicitly omitted" with unset or var?.
Fixed crashing when a ComObject is passed to a for-loop with only the second variable specified.
