v0.2.1

A large number of improvements to non-code diffs, and adding more robust tests for non-code content.

Added

• Pictures (PNG, JPEG, GIF, WebP, BMP, ICO, TIFF) are diffed instead of reported as "Binary file
  differs": what each side is (format, size, color type), how much of it changed and where, as
  rectangles of changed pixels. Pixels compare perceptually, so re-encoding noise is not a change.
  Headless and git diff print this as a short report and --mode json adds a picture object.
  The TUI shows the two pictures with the changed regions outlined, and t cycles to a
  difference, blend and swipe view; it draws real pixels where the terminal speaks the kitty,
  sixel or iTerm2 graphics protocol and Unicode half blocks everywhere else.
• Animated GIF, PNG and WebP pictures are compared frame by frame, the frames aligned the way
  lines are: the report says which frames changed, which were added or removed, and whether the
  same frames now show for different times. In the TUI, , and . step through the frames and
  space plays the animation.
• + and - zoom into the same part of both pictures, up to 32x, and Shift+h/j/k/l pans:
  for a large screenshot whose change is a few pixels.
• Inside tmux, the TUI draws pictures with the graphics protocol of the terminal in front of the
  pane, as tmux knows it, rather than whichever attached client answered the query: a kitty on a
  desk no longer makes a phone's terminal attached to the same session show crossed-out boxes.
  b switches every picture to half blocks and back, and OMNIDIFF_GRAPHICS=halfblocks (or
  kitty, sixel, iterm2) overrides the detection.
• Archives, fonts, cursor themes, message catalogs and PDFs are diffed by what they hold, member
  by member: a zip's or tar's files (jars, Office documents and EPUBs are zips; gzip, xz and
  bzip2 streams are opened too), a font's glyphs and names (TrueType, OpenType, WOFF, WOFF2,
  EOT), a cursor's sizes and frames (Windows .cur and .ani, X cursors, Hyprland .hlc), a
  gettext .mo or Qt .qm catalog's messages, a PDF's pages. Members match by name and only
  the changed ones are opened: each is diffed by what it is - a picture as a picture, text by
  lines, a nested archive as an archive. The report lists the members that changed, were added or
  were removed; --mode json adds a content object, which a picture pair carries too. In the
  TUI the members are listed beside the selected one, a shows the unchanged ones as well, g
  shows every changed glyph or picture at once, and Enter opens an archive inside an archive.
  A text member is diffed by OmniDiff in its own language, its long lines wrapped and cut to the
  changes (J/K step through them), and Enter opens it in the full diff view; a Java class
  file in a jar is diffed as a listing of its fields, its methods and what each method calls,
  reads and loads.
• What happened to a picture or a member is said in one of six levels, by how hard it is to see
  and what the after side is: invisible (only bytes differ), imperceptible (seen only once
  highlighted), artifacts (what compression, resampling or a formatter leaves behind), edited,
  redrawn (the same thing made anew) and replaced; with tags for a picture resized, cropped,
  retimed or given frames, and for a container given members. Pictures of one aspect ratio and
  different sizes are compared at the smaller size; --mode json reports, per comparison, the
  pixels that differ at all and the clearly changed ones beside those that changed.
• Text in UTF-16 or UTF-32 (announced by a byte order mark) is read as text and diffed like any
  other file instead of reported as binary; --mode json names its encoding.

Changed

• XML formats with an extension of their own are diffed with the XML grammar instead of line by
  line: .svg, .plist, Qt .ui/.qrc, MSBuild .vcxproj/.csproj/.props/.targets, .xib,
  .storyboard, .xaml, .resx, .xsd/.xsl, .xlf, .kml, .gpx and more (see the README's
  language list). A file under one of these names whose content is not markup is still diffed as
  plain text.
• Building OmniDiff needs Rust 1.92 or later (was 1.88): the picture view's graphics library
  needs 1.90, and the PDF renderer 1.92.
• The TUI shows the two files side by side from 200 terminal columns (was 220); narrower
  terminals still show one panel at a time.

v0.2.0

CodeDiff is now OmniDiff. The old name is a registered trademark, so everything was renamed.

Changed

• Renamed from CodeDiff to OmniDiff. The crate, binary, packages, editor extensions and
  repositories are all omnidiff now: install omnidiff (cargo install --locked omnidiff, the
  omnidiff deb from https://ivankovic.github.io/omnidiff/apt, brew install ivankovic/omnidiff/omnidiff, the ivankovic.omnidiff VS Code extension, omnidiff.nvim),
  then rerun omnidiff git configure and omnidiff jj configure, since a configuration that
  names codediff points at a binary that no longer updates. The apt repository moved with the
  GitHub Pages site: replace ivankovic.github.io/codediff/apt and the
  codediff-archive-keyring.gpg key file in your apt sources with the omnidiff ones (see the
  README). The codediff crate and the codediff packages stay available for now and are
  retired in a later release.
• The config moved to .omnidiff.toml, $OMNIDIFF_CONFIG and ~/.config/omnidiff/config.toml.
  For this release the old names are still read, and ~/.config/codediff/config.toml is moved to
  the new place the first time it is needed.
• Code copied to several places is shown as such: when a statement or declaration of some size
  appears once before and twice after (or the reverse) in two branches of one if, every copy
  paints as a move of the original instead of one being matched and the rest inserted.
• A comment of three or more words that moves inside a function, class or other construct that
  survives the change is shown as moved, instead of deleted and re-inserted.
• A run of comments or small statements that changes length is aligned by similarity, so the
  entries that stayed are matched instead of the whole run being deleted and re-inserted.
• A leaf renamed across two different constructs (one identifier of a replaced expression reused
  in the new one) is shown as deleted and inserted rather than as an in-place update.
• Library: ASTDiff records N:M groups next to its one-partner node maps (add_group), and its
  node maps can no longer disagree about a pair (is_valid checks it).

v0.1.1

Responding to initial user reports for v0.1.0.

Note the removal of "--web" and sending users to CodeReview instead.

Changed

• Tabs display at tab stops, in the TUI and in headless output, instead of as one space.
• The TUI uses the nearest 256 colors when the terminal does not advertise 24-bit color (macOS
  Terminal.app).
• --minimal, --full, --whole-updates and --paint-reindent-moves apply in the TUI too, for
  that run only.
• --review rejects a BEFORE/AFTER pair and --mode, and --headless rejects --mode, instead
  of ignoring one flag.
• codediff git configure writes the resolved path of the running binary to diff.external.
• change N/M counts changes in the order n walks them.
• The render-options badge names what differs from --full.
• Panel titles name languages as people write them (C++, Lua, Markdown). The JSON language
  values are unchanged.
• Library: the diff::solve_* pass modules are crate-private, ASTDiff::is_valid has no after
  parameter, and NodeCache takes a lifetime (see Fixed). Breaking for library users, against
  the policy above; the library API was never meant to be relied on (see the crate docs).

Fixed

• The TUI cursor lands on the right column on lines with non-ASCII text.
• Ctrl-C quits from every screen, and Ctrl-E scrolls instead of opening $EDITOR.
• The theme dialog opens on the syntax theme in use, and accepting a preset keeps the saved Custom
  palette.
• Home and End move the cursor, not only the view.
• $VISUAL/$EDITOR may carry arguments (code -w, emacsclient -t).
• Omitting --whole-updates no longer switches a saved "Whole-pair updates" setting off.
• The TUI exits when its input stream closes.
• A block whose children were all deleted no longer takes its whole subtree with it: code matched
  inside it (a body moved from an if into an unless) is shown as matched, not deleted and
  inserted.
• Library: NodeCache borrows the Code it was built from, so a cache that outlives its Code
  no longer compiles; before, safe code could read freed memory through it.

Removed

• The browser front end (codediff-web) and the web Cargo feature. Breaking for anyone who
  installed with cargo install codediff --features web; for reviewing changes in a browser, use
  codereview. The GitHub Pages showcase is unaffected.
