Release 5.5.7 (https://www.scintilla.org/scintilla557.zip) Released 8 June 2025 1. Add SCI_SCROLLVERTICAL method to restore view position and maintain it while performing line wrapping. 2. Add SC_UNDO_SELECTION_HISTORY_SCROLL flag to SCI_SETUNDOSELECTIONHISTORY which controls whether undo and redo restore vertical scroll position. 3. Tweak SC_MARK_BAR to be slightly wider by using next higher whole pixel instead of next lower for margin width / 3. 4. Scale images in autocompletion lists with SCI_AUTOCSETIMAGESCALE to match high DPI screens. Initially only on GTK and Qt. 5. Fix wrapping bug for UTF-8 where \r\n could wrap between the characters. Notepad++ Pull Request #16373. 6. Fix crash during painting when scroll bars changed. Bug #2481. 7. On GTK, reset vertical scroll bar synchronously in SCI_SETDOCPOINTER to fix bug where scroll position not restored in non-wrap mode. Bug #2416. 8. On GTK, fix IME problem when tentative composition interfered with delete surrounding. Feature #1476. 9. On GTK, update IME cursor position inside retrieve surrounding to better position candidate window. Feature #1488. Release 5.4.5 (https://www.scintilla.org/lexilla545.zip) Released 8 June 2025 1. Dart: Add error state SCE_DART_STRINGEOL for unterminated string. Pull request #315. 2. Makefile: Add a keyword list to makefile lexer to highlight GNU Make directives like 'ifdef' and 'vpath' as SCE_MAKE_PREPROCESSOR since these are similar to NMAKE directives like '!IFDEF'. 3. Nix: Add error state SCE_NIX_STRINGEOL for unterminated string. Pull request #315. 4. TOML: Add error state SCE_TOML_STRINGEOL for unterminated string. Pull request #315. 5. Zig: Add error state SCE_ZIG_STRINGEOL for unterminated string. Pull request #315. Close #16649
