Fix drag getting stuck to cursor on release, bump to 1.2

OnMouseUp only fires while the cursor is still over the frame at the
instant the button is released, which a quick flick of this small
frame easily misses, leaving it stuck following the mouse forever.
OnUpdate now polls IsMouseButtonDown every frame and stops the drag
as soon as the button is released, independent of cursor position.

 ## [Unreleased]
 
+## [1.2]
+### Fixed
+- Drag could get permanently stuck following the cursor: `OnMouseUp` only fires while the mouse is still over the frame at the instant the button is released, which a quick flick of this small (90x24) frame easily misses. `OnUpdate` now polls `IsMouseButtonDown("LeftButton")` every frame and stops the drag as soon as the button is released, regardless of where the cursor ends up.
+
 ## [1.1]
 ### Added
 - `/octolat copyerrors`, opening a copy-errors window: a multi-line `EditBox` pre-filled with the error log and auto-highlighted, so the text can be selected and copied with Ctrl+C (vanilla WoW's chat frame doesn't support text selection).
