Each archive carries the licences (LICENSE-MIT, LICENSE-APACHE, LICENSE-OFL), THIRD_PARTY_NOTICES.md and the dependency notices (THIRD_PARTY_LICENSES.html). SHA256SUMS has the SHA-256 of every archive; release-manifest.json records the commit they were built from. Install guide: https://github.com/PSCatLabs/pscat/blob/main/docs/guides/getting-started.md

pscat 0.6.0

The first release published outside this repository.

Highlights

• Install without a checkout: cargo install pscat from crates.io, or a
  prebuilt binary from the GitHub Release (macOS arm64/x86_64, Linux
  x86_64/arm64 musl, Windows x86_64). PostScript libraries (lib/) are
  embedded in the binary.
• Font packs: pscat fonts install downloads the extras, TeX Gyre and
  CJK/Thai packs from the fonts-2026.10 release, checked against a SHA-256
  pinned in the binary.
• Subcommands: pscat handwrite, pscat typewrite and pscat photo-etch
  are built into the binary.
• pscat-mcp declares its MCP protocol versions, enforces timeouts and size
  limits, and confines out_path. A Claude Code plugin bundles the skills and
  the server.
• Licensing: code is MIT OR Apache-2.0, embedded fonts are OFL-1.1, and the
  art is CC0-1.0 (THIRD_PARTY_NOTICES.md).
• Plus paint and dry media kits, the typewriter's released-document look,
  mathkit additions, Level 3 clipsave/cliprestore, and new gallery pieces.

Fixes

• Fix hollow centre when a tiny curve is stroked wider than its diameter (#170)

• Fix pkoil porad cursor corruption for multi-subpath strokes (#90)
• Fix ShowCtx's fixed unicode_mode: re-segment per glyph on mid-show font switch (#70)
• work-issue: fix crash-resume race + branch-name bug (#29); address #33 punch list (#34)
• Fix silent stroke-drop in --pdf-only export; add PDF document metadata (#8) (#23)
• Fix work-issue deadlock: crashed in-progress issues must resume, not halt

Features and changes

• Interp: dropping an Interp frees systemdict/userdict (Rc cycle) (#632)
• plugin: Claude Code plugin and marketplace for the skills and pscat-mcp (#569 part a) (#634)

• typewriter: a clogged counter takes the bleed colour and the worn lane's weave (#539) (#588)
• released: a gem paper clip with a dent and a rust ghost, not three ellipses (#587)
• typewriter: /worn's /Ribbon is 0.55, so the worn elite weighs x0.76 of T10, not x0.66 (#520) (#586)
• released: a copy softens its stamps, notes and redaction bars (/Soften) (#582)
• typewriter: /MisStrike and /MisStrikeScale, the mis-strike rate and size as machine and typist traits (#584)

• typewriter: the mis-strike's y tail is 2x, not 4x (the d in restricted) (#550)
• released: thin-stroke dropout under a photocopy (/Dropout) (#548)

• typewriter: ribbon ink extras, a worn band and two-colour bleed (opt-in) (#540)
• currentrgbcolor: round the readback to the f32's short decimal like gs; alpine_lake still regenerated (one pixel, one level) (#536)
• drykit: split a chunk past dkbudget, refuse a too-wide stroke before drawing (#324) (#537)
• released: a copy's haze grain is imagemask stencils at the scans' strength (#474) (#529)
• artkit: scin refuses a hand-built region that carries a procedure, with no per-call walk of built ones (#503) (#533)
• Evening Stream: the cloud bodies' wet edge asks the sky at each stroke (pkwet /PerFill) (#525)
• Alpine Lake: notes on pulling the plane-streak re-lay into the reflection (#508 measured; invisible) (#524)
• typewriter: elite takes the ribbon ink separately from pica (#511) (#522)
• pscat: a Type 3 BuildChar runs in its own gsave level, so cliprestore and grestore there give back the state at show (#500) (#527)
• pscat: currentcmykcolor, currentcolor, currentlinecap, currentlinejoin, currentmiterlimit, currentstrokeadjust, as gs does (#523)

• typewriter: a light strike thins, not only dots out (#514)

• released: a photocopy's paper keeps a grey haze, mottle and grain (/Haze) (#466) (#475)
• paintkit: pkwet's directional /Layers cap is 32; the canvas specimen's wet pull no longer bands (#417) (#485)
• mathkit: \mod and \pod, \nolimits on a brace, a column's wander, alignat, mkbrace (#480)
• paintkit: pkfan runs are cut into overlapping ribbons for pkwet /FillLength (#502)
• pscat: Level 3 clipsave and cliprestore, scoped per gsave level as in Ghostscript (#501)
• paintkit: pkwet /FillLength cuts a long loaded run into per-stop fills so /PerFill follows a gradient along it (#499)
• check_md_links: a ref must end at a boundary, so blob/mainline is not main (#481) (#498)
• pscat: .sameclip, a clip identity query; drykit sees a bound wrapper's grestore in a dkbatch (#488) (#496)
