Changelog

All notable changes to Picvert are documented here. Version numbers follow Semantic Versioning.

[1.3.1] — 2026-05-11

Added

  • Update progress overlay — when the user confirms an update, a centred card now shows a smooth percent bar (downloading) and an indeterminate sweep (installing). Both phases translated in the four UI languages. Driven by update-progress events that install_update emits on every chunk and on download completion.

Fixed

  • Windows could launch multiple Picvert instances — added tauri-plugin-single-instance (Windows + Linux only; macOS already single-instances via LaunchServices). A second launch now wakes the existing main (or compact) window instead of spawning another process.

[1.3.0] — 2026-05-11

Added

  • PDF first-page thumbnail cache — repeated renders return the cached PNG instead of re-rendering through PyMuPDF on every list refresh.
  • Retry failed file button on each failed row.
  • Localised engine errors — error kinds (unsupported / not_found / bad_request / internal / engine_died) translate to the active UI language instead of always showing the English Python message.
  • Click any thumbnail to open the source file in the OS default app (Preview, Adobe Reader, etc.).
  • Per-extension breakdown beside the file count (5 · PDF 4 · JPG 1).
  • Window state persistence — main window remembers its last position / size across launches.
  • Hover spin on the capsule weather icon.

Changed

  • Batch conversion runs in parallel — sidecar thread pool of 4 workers, JS dispatches up to 4 in-flight conversions. ≈3-4× faster on multi-image / multi-page-PDF batches.
  • Compact window is pre-created at startup (visible: false in tauri.conf.json) to dodge a WebView2 hang on Windows where a runtime WebviewWindowBuilder::build() for a second webview never returned.
  • Folder walk hardened — defends against symlink loops and unreadable subtrees; clamps to 5000 files / drop.
  • Switched to tauri-plugin-opener for shell.open (the previous tauri-plugin-shell open API is deprecated).
  • Minimal macOS menu — Picvert / Edit / Window only (was an auto-generated File / View / Help layout with empty submenus).
  • APP_VERSION now reads from package metadata so release bumps only touch pyproject.toml.

Fixed

  • Windows capsule freeze — main panel blanked out and never became the capsule because the second-webview build() call hung. The pre-created window approach makes this transition a show() instead.
  • Capsule sometimes didn't appear after toggling main ↔ compact several times (.leaving class stuck on the body).
  • App could exit instead of going to capsule on first close — hide-main / build-compact ordering left zero visible windows briefly.
  • Capsule corner halo — replaced filter: blur(20px) on .card-glow with radial gradients (compositor leaks past rounded clip on transparent NSWindow).
  • Tab outline on capsule — removed the default focus ring.
  • Auto-updater wired up properly — bundle.createUpdaterArtifacts: true emits .app.tar.gz / .exe.sig pairs; regenerated minisign key pair after the previous one was base64-corrupted.
  • Sidecar consistent CSV naming + multi-sheet XLSX handling.
  • Capsule position clamps to current monitor when dragged off screen.

[1.2.1] — 2026-05-11

Added

  • SVG preview in the file list — SVG files now render inline thumbnails instead of just a text badge.
  • PDF first-page thumbnails — sidecar renders ~96 px PNGs on demand through a new preview RPC action (~50–100 ms per file, cached).
  • Click any thumbnail to open the source in the OS default app (Preview, Adobe Reader, etc.). Hover shows a darken-overlay + external-link icon.
  • Per-extension breakdown next to the file count, e.g. 5 · PDF 4 · JPG 1 (request: "old version had this").
  • Hover tooltip on Max Width input — explains "leave blank = no downscale; type a number to cap every image at that width". All four languages.
  • Hover spin on the capsule weather icon (3.4 s/turn).
  • Minimal macOS app menu — Tauri's autogenerated File/View/Help submenus are replaced with just Picvert / Edit / Window.

Changed

  • Batch conversion is now parallel — sidecar runs a 4-thread pool; JS dispatches up to 4 in-flight conversions. ~3-4× faster on multi-image / multi-page-PDF batches.
  • Auto-updater wired up — bundle.createUpdaterArtifacts: true now emits .app.tar.gz / .exe.sig pairs, and latest.json carries the real per-platform signatures. (v1.2.0 release contains the new public key, so 1.2.0 → 1.2.1 will be the first auto-update.)
  • Tauri updater key pair regenerated — the old TAURI_SIGNING_PRIVATE_ KEY secret was base64-corrupted (unnoticed until createUpdaterArtifacts was enabled).

Fixed

  • Capsule sometimes didn't appear after toggling main ↔ compact several times — expandToMain() left a stale .leaving class on the body, so the capsule was painted at opacity:0 on next show. Both JS (finally-remove) and Rust (eval also wipes .leaving).
  • App could exit instead of going to capsule on first close — hide_main_show_compact was hiding main BEFORE building compact, leaving zero visible windows briefly. macOS sometimes treats this as "all windows closed" and exits. Now compact is shown first.
  • Capsule corners showed a faint right-angle halo — .card-glow used filter: blur(20px) which the compositor sometimes leaks past the parent's rounded clip on a transparent NSWindow. Replaced with radial gradients (no blur leak).
  • Tab on capsule painted an outline ring — removed the default focus outline; capsule is a draggable widget, not a keyboard surface.

[1.2.0] — 2026-05-11

Added

  • JPEG / WEBP quality slider (60–100, default 90). Saved across launches. Visually-lossless 90 produces ≈half the file size of the previous fixed 100.
  • Max width input (px) — proportionally downscale every output. Useful for exporting phone photos at web/social sizes.
  • Drop folders — dragging a folder onto the dropzone (or capsule) now recursively expands it to all supported files. Capped at 5000 files / drop.
  • Progressive + optimized JPEG encoding (optimize=True, progressive=True).
  • WEBP encoding now respects the quality slider with method=6 (best compression effort).

Changed

  • PDF page render path also honours quality and max_dim (was hard-coded to PDF's 100% quality and original render size).
  • engine_cancel now actually kills the sidecar — multi-page PDF conversions are interrupted immediately. The engine respawns on next request (~0.17 s onedir cold start).
  • File picker switched from HTML <input type="file"> to Tauri's native dialog (pick_input_files) so the engine receives real absolute paths on every platform.

Fixed

  • SSRF in http_get_text: now host-allowlisted to the three weather/geo APIs and HTTPS-only. Was previously a generic Rust-side fetch tunnel.
  • Engine-death recovery: when the sidecar crashes, all in-flight awaits get a clean engine_died error and the next call respawns rather than hanging forever.
  • PDF open failure no longer silently returns written: 0 — now surfaces as an internal error in the UI status row.

Removed

  • Tk-era leftovers: picvert/i18n.py, picvert/config.py, picvert/paths.py, picvert/logging_setup.py, picvert/single_instance.py (and their tests). The Python side is now ~370 lines smaller.
  • Unused i18n keys, dead picvert:show-help listener, redundant shell:allow-execute capability, unused geocoding-api.open-meteo.com CSP entry, platformdirs dependency.

[1.1.0] — 2026-05-10

Added

  • Cross-platform tray icons (macOS template / Windows / Linux variants).
  • Capsule ↔ main window scale + fade animations.
  • Real document conversion across DOCX ↔ XLSX ↔ CSV (six directions).
  • HEIC read / write via pillow-heif.
  • Compact-mode floating widget with live time + IP-based weather.
  • macOS menu bar tray with multi-language menu, About + Check for Updates.
  • Keyboard shortcuts: ⌘O, ⌘⏎, ⌘L, ⌘.
  • Toast notifications + system notifications on batch completion.
  • Help dialog with supported-format chips.
  • Persistent picvert-engine sidecar in --line-mode for ~38× faster per-call latency vs --onefile.

Changed

  • Switched PyInstaller from --onefile to --onedir: cold start 6.5 s → 0.17 s.

[1.0.0] — 2026-05-09

Initial monolithic release (Tk GUI). Retired in favour of Tauri shell + Python sidecar in 1.1.0.
