1.1.3 - 2026-04-09

Bug Fixes

• Fix SGR parameter bounds checking in escape parser (CSI 38/48/58) - prevents IndexError from malformed escape sequences
• Fix ZModemMux memory leak - added dispose() method to cancel StreamSubscription
• Fix CellAnchor owner null-safety - improved assert messages for detached anchors
• Fix Buffer._savedCursorStyle mutation - now uses copy() for proper immutability
• Fix GraphicsManager cleanupStalePlacements never called - integrated into terminal image clearing

Code Quality

• 1184 tests passing

1.1.1 - 2026-04-08

Bug Fixes

• Fix ZModem protocol parsing: correct LF constant (0x8a → 0x0a) and add missing XON consumption in hex frame parsing
• Fix ZModem session lifecycle: keep session open when onFileRequest is null, add ZFIN handling in _ZReadyToSendState
• Fix ZModem test data: complete ZRINIT frames (19 bytes with CRC and XON), correct ZFIN CRC (0x022d)
• Fix assertion in zmodem_test.dart: use contains(equals(...)) for proper list matching
• Fix simple_ext_test.dart import path: use package:kterm/kterm.dart
• Fix typo: unkownEscape → unknownEscape in escape parser
• Fix comment typo: "cornor" → "corner" in buffer.dart

Code Quality
