Patch notes

-- 2.0.4

• Bugfixes:
  • Fixed an issue where Blizzard skin proxy mode made the multiline editor render transparently.
  • Fixed an issue where spellcheck highlighting desynced from the text in the multiline editor when the text wrapped across multiple lines.

-- 2.0.3

• Bugfixes:
  • Fixed issue where the post queue would get stuck if you posted to Party, Instance or Raid Chat while you were a leader in one or more of these.
  • Fixed a bug where YALLM didn't correctly boost words to the autocompleter.
  • Fixed numerous visual bugs in the overlay, ghost text and the multiline editor.
  • Fixed minor alignment bugs in the settings dialog.

-- 2.0.2

• Bugfixes:
  • Multiline Underline Alignment: Spellcheck highlight underlines in multiline mode were drawn 1 px too far right. Fixed.
  • math_min crash fix: Fixed a nil value error in Autocomplete.lua when the dismissal penalty code ran — math_min was used but not localised.

-- 2.0.1

• Structural Cleanup:
  • Monolith Split: The three largest files — Interface.lua (4 100+ lines), Spellcheck.lua (3 300+ lines), and EditBox.lua (2 900+ lines) — have each been broken into focused sub-modules. Spellcheck now loads as 6 files, EditBox as 5, and Interface settings as several panel files.
  • Spring Cleaning: Purged a lot of legacy "orphaned" code and redundant N-gram relics that were just taking up space. The engine is leaner and faster.
  • Hardened Initialisation: Added better sanity checks during boot. If something critical (like the UI cache) fails to load, Yapper will now tell you exactly what went wrong instead of failing silently.
• Stability & Bug Fixes:
  • Memory Management: Killed off several memory leaks and ensured dictionaries don't duplicate on reload.
  • Dictionary Base Protection: Fixed a bug where switching locale could unload the base dictionary that a delta locale (e.g. enGB) depends on, causing the spellchecker to go partially blind.
  • Fixed "Confused" Suggestions: Resolved a bug where the spellchecker would occasionally point at the wrong words in a sentence.
  • UI Polish: Fixed alignment issues in the settings menu where buttons and input boxes were getting cut off.
  • Visual Fixes: Suggestions no longer "travel to Narnia" on long, sideways-scrolling messages.
