cbzLab 2.1.0

Downloads: cbzLab-2.1.0-win-x64.exe for Windows, cbzLab-2.1.0-linux-x64 for Linux
(run chmod +x on it first). The -debug.zip files add debug symbols for crash reports;
the .zip/.tar.gz files are for the in-app updater in older versions.

A review-driven fix release: safety, correctness, speed, and settings that had
quietly stopped working.

Safety

• A settings backup can no longer write files outside the settings folder.
  Import used to trust every path inside the .cbzlab file, so a crafted
  backup could drop a file anywhere you can write; such entries are now
  refused and counted.
• Converting a book to the other format no longer silently overwrites a file
  that already has the new name. You're asked first, a clash with another book
  open in cbzLab is refused, and the status says the original was kept.
• 7-Zip is no longer used to write CBR. Asked for a .cbr, it reports success
  but writes its own 7z format, which cbzLab and most readers can't open. Only
  WinRAR's rar tool is used (now also found in its default install folder), and
  every CBR save is checked for the RAR signature before replacing anything.
• Settings files are written atomically, so a crash mid-write can't truncate
  them, and a hand-edited file with a typo is set aside rather than overwritten.
• The ComicVine API key no longer ends up in the log.

Things that didn't work

• Auto Page Count on open, Auto-select first file and Clear filter on open
  were in Settings but did nothing. All three work again.
• Existing installs never received new themes or fields: schema.json and
  themes.json were copied once on first run and never updated, so Tokyo
  Night, Catppuccin, Gruvbox, True Black and High Contrast silently fell back
  to Solarized Dark. They're now kept current - an untouched copy is replaced,
  an edited one keeps your changes and gains what's missing.
• ComicVine issue lists were cached forever, so an ongoing series never showed
  its new issues. Cached answers now expire, the cache is capped, and series
  longer than 500 issues are fully reachable.
• A book with a macOS __MACOSX folder had its junk ._ files counted as
  pages (inflating Page Count), possibly used as the cover, and joined into
  combined books as broken pages. They're now ignored everywhere.
• Update downloads timed out after 15 seconds, and the updater broke on a
  user folder containing an apostrophe or accented letter.
• On Linux, two books whose names differ only in case were treated as one.

Metadata

• Partial dates like 2019-03, March 2019 and Mar 2019 no longer gain a
  made-up day of 1, and a half-typed date no longer writes a wrong year while
  you're still typing it.
• Validation now enforces Month 1-12, Day 1-31, a four-digit Year and no
  negative counts.
• Guess from Filename reads "(of 12)" as Count and ignores release tags like
  "(Digital)" in the series name.
• A duplicated tag now shows the value a save actually edits, new elements are
  written in the ComicInfo schema's order, and a book with unreadable
  ComicInfo.xml says so when opened.
• ComicVine's plain "artist" credit now fills Penciller and Inker.
• Trim Footers keeps WebP pages as WebP.

Speed and polish

• Opening a CBZ and loading its cover read only what's needed instead of the
  whole archive: 2 to 27 times faster per book on the files tested.
• Batch edits in "Modified first" sort no longer freeze the app.
• Autosave only rewrites changed files, in the background; covers decode off
  the UI thread, a few at a time.
• Covers are shown whole instead of cropped at the top and bottom, and field
  boxes keep the same width on every tab.
• Logs older than 30 days are pruned, and backups no longer include autosave
  drafts.
