OS3 68000 Package Replacement

The DOpus5_101_os3-68000.lha archive was replaced on May 9, 2026 to fix a startup Guru 8000 0003 on plain 68000 AmigaOS 3 systems. The crash was caused by an odd-aligned built-in CatComp string block being parsed with word/long reads while scanning modules at startup.

Highlights

• Added SFTP support to the FTP module and improved FTP/FTPS/SFTP UTF-8 filename handling through codesets.library when available.
• Added first-class AROS i386 and x86_64 release packages, plus a separate AmigaOS 3 68000 package for plain 68000 machines.
• Improved format.module handling for Long File Names, including FastFileSystem version gating and PFS awareness.
• Improved backdrop and icon-mode behavior, including Workbench-order type sorting, row-fill cleanup, stable label baselines, and Resize to Fit menu gating.
• Added GUI controls for previously hidden Environment options and cleaned up dead ENV: variables.
• Refreshed DOpus5.guide, clarified public headers, updated package layout, and aligned drawer naming under DOpus5.

Late-Cycle Fixes

• Fixed OS3 titlebar drawing so the clock, memory text, and custom title text use the real screen bar height on newer intuition.library versions.
• Restored Environment / Lister Options spacing around the Icon Action double-click row.
• Fixed the About requester copyright block so it stays within the requester.
• Removed the dead Custom Screen Title Internet Time code from the formatter, configuration popup, and translated catalogs.
• Fixed Custom Screen Title memory substitutions so plain byte values honor the locale thousands-separator setting, matching the K/M/G/S forms. This closes issue #81.
• Hardened print.module string handling for user-supplied title, output path, wrap buffer, and header/footer text, closing the V-001 CWE-120 buffer-overflow report.
• Kept that print.module hardening compatible with the OS3 toolchain by using local bounded copy/append helpers instead of unavailable BSD strl* symbols.

Validation

The 5.101 tag was built by GitHub Actions run 25598614157. The run passed host FTP/SFTP tests, AROS debug builds, debug and release package builds for OS3, OS3 68000, OS4, MorphOS, i386 AROS, and x86_64 AROS, and uploaded the release assets above.

The replacement OS3 68000 archive was built locally with sacredbanana/amiga-compiler:m68k-amigaos using make os3-68000 release debug=no. The packaged DOpus5/Libs/dopus5.library was extracted and compared against the rebuilt source/bin.os3-68000/dopus5.library.
