0.0.22

What's Changed

New Features

• window chrome matches current theme by @freepicheep in #33
• Bracketed paste implemented
• Add support for reporting iTerm2 settings (there were already in place, we just did not report them).
• blinking cursors pause as you type

Improvements

• More performance optimizations to SwiftTerm, we are very close to Ghostty 1.3.1 in performance terms, a bit better in some, but still slower than Ghostty/dev which has improved even more.

New Contributors

• @freepicheep made their first contribution in #33

v0.0.20

• This brings a new 3D selector, extending the existing 2D selector.

• Startup now waits until activation and scene restoration before
  opening a window, and only opens when no documents or terminal windows
  already exist. Document launch is suppressed by default to avoid
  duplicate untitled instances.

• Do not spawn Tecolot into a different desktop.

• Terminal paste handling now prefers the active process control bytes
  for filtered paste. Like Xterm does.

• Settings Escape closes via an explicit key-down monitor, so it works
  all the time.

From SwiftTerm

• LocalProcess: fix for race on shutdown.

• Implementation of new DEC Private modes:

• ?2004 — Bracketed paste
• ?2031 — Color scheme update reporting
• ?2033 — Visibility reporting
• ?2048 — In-band size reporting
• ?5522 — Kitty clipboard/paste event mode
• ?2027 — Grapheme clustering mode (implemented as permanent, no-op support in terminal behavior)
• ?117 — Treated as “permanently reset” in mode query responses

v0.0.19

• Tecolot now offers more ways of picking a theme and 2D visualizations to help you pick the right palette for your lifestyle.
• Fixes an annoying focus stealing bug

v0.0.18

Tecolot

Theme system improvements

• Added theme lineage tracking (baseThemeName) to TerminalTheme, so derived themes know which built-in theme they were forked from.
• Added first-class theme forking/duplication helpers in ThemeStore:
  • Smart de-duplicated naming (<theme> (Custom), <theme> copy, with numeric suffixes)
  • Built-in themes are no longer edited directly; edits create a non-built-in fork.
  • Custom themes duplicate with copy semantics while preserving lineage.
• Added robust theme operations in profile settings:
  • In-place theme editing section with name editing, duplicate/revert/delete actions, and color pickers for background/foreground/selection/cursor + all 16 ANSI colors.
  • Built-in/custom differentiation in previews and cards.
  • “Revert to base theme” action for custom themes created from built-ins.

Theme browser + picker refinements

• Refactored theme browser into reusable sectioned view model:
  • Favorites are separated from others and sorted alphabetically.
  • Supports paged mode (popular/more) and full list mode for chooser sheets.
  • Added optional “Done” action for modal usage.
• Updated theme cards:
  • Added hover/focus-friendly favorite toggle on card.
  • Added “CUSTOM” badge on non-built-in themes.
• Duplicate action for built-in themes now uses centralized forking logic.

Profile/settings reliability updates

• Updated profile update flow to return success/failure (Bool) so multi-step operations can roll back on storage failures.
• Theme edits in settings now use safer result-handling and rollback when persistence fails.
• Added delayed/batched save behavior for theme edits to reduce churn and preserve responsiveness.

App behavior and maintenance

• Fixed app reopen behavior: reopening with no visible windows now opens a new window.
• Release workflow now explicitly requests contents and actions permissions for release/appcast dispatch needs.
• Updated SwiftTerm dependency revision in Package.resolved.

SwiftTerm Highlights

• Added formal fuzzer infrastructure and coverage for parser/stream/OSC behavior, plus documentation for live and corpus-driven fuzzing.
• Implemented XTGETTCAP support (DCS +q) using generated terminfo-based reply data.
• Added substantial hardening fixes around wide-cell seams, OSC bounds, and local process lifecycle safety.
• Expanded benchmarking and profiling tooling with dedicated hardening workloads and an executable profiler.
• Added extensive new regression test coverage (including Ghostty corpus and seam/OSC/XTGETTCAP tests).

---

New Features

• Terminal protocol support

  • Added XTGETTCAP DCS handler with multiple key support, malformed-key handling, terminal name (TN) responses, and limits.
  • Added generated SwiftTermTerminfo table from checked-in swifterm-terminfo.
  • Added docs for new Kitty graphics types and integration (KittyGraphicsIntegration, configuration/policy/snapshot docs).

• New hardening and performance knobs

  • TerminalOptions.maximumOscBytes added (default 65 MB).
  • BenchmarkOptions-adjacent improvements for profiling:
    • Added hardening benchmark set in VTEBenchWorkload.
    • Added SwiftTermProfile tool for headless profiling.
  • Added profiling support for seam check counters (SWIFTTERM_SEAM_COUNTER).

• Fuzzing/testing assets

  • Added Docs/fuzzing.md and Makefile targets for corpus replay and live fuzzing.
  • Added Tools/import-ghostty-fuzz-corpus.swift to import Ghostty fuzz corpora.
  • Added new fixture archives and provenance docs under Tests/SwiftTermTests/Fixtures/GhosttyFuzzCorpus.

Fixed / Reliability Improvements

• Wide-cell correctness & seam integrity

  • Added destination-keyed seam repair in buffer writes.
  • Added bulk scalar insertion path for valid homogeneous scalar runs.
  • Fixed wide-character seam corruption risks in many editing/movement paths and margin-restricted operations.
  • Added integrity regression tests asserting wide-cell invariants.

• ESC/OSC parser hardening

  • Reworked OSC buffering with explicit size caps and capped retained capacity.
  • Added parser-level limit for oversized OSC payloads and memory release path after reset/completion.
  • Replaced separator parsing representation (_parsTxt -> bitmask) for safer, cheaper CSI separator handling.

• Local process lifecycle safety

  • Reworked LocalProcess lifecycle to avoid stale callbacks and PID reuse races.
  • Added bounded output-drain + reaping behavior to preserve queued output before termination notifications.
  • Added explicit termination escalation (SIGTERM then SIGKILL) and configurable delays.
  • Added state phases and generation-based guards for restart safety.

• Pipeline robustness

  • Added TerminalIOPipeline.drainAvailableAndShutdown(timeout:) for bounded shutdown draining.
  • Introduced explicit run phases (streaming/draining/quitting) and control wakepipe for deterministic stop behavior.
