Highlights

This release adds contained visual and animated SVG previews and restores animated GIF and WebP upgrades.

Added

• Preview self-contained .svg files as bounded visuals, with a performance-first static render followed by a contained animation upgrade for supported SMIL documents, based on SVG work by @kailiang0120 in db627cb.

Fixed

• Deliver decoded GIF and animated WebP frame sets through the worker protocol instead of discarding the animation upgrade and leaving only the first frame visible, with contributions from @tanveyhong in 6065d2a.
• Reserve .svg for the visual provider so unsupported markup no longer appears as plain text.

Security

• Disable SVG filesystem and network resource resolution, system-font discovery, scripts, event handlers, entities, and external references in the visual and animation paths.

• CycloneDX SBOM
• GitHub build-provenance and SBOM attestations are created before publication.

Highlights

This release adds native hover video playback and substantially broadens source-text preview coverage.

Added

• Preview .svg files as inert markup source text through the existing contained text provider.
• Extend text previews to documentation markup (.markdown, .mdx, .rst, .adoc, .tex), more structured data (.json5, .jsonl, .ndjson, .plist, .config, .hcl, .tf, .tfvars, .proto, .graphql), more languages (.vb, .fs, .scala, .groovy, .swift, .dart, .lua, .r), web tooling (.vue, .svelte, .astro, .scss, .sass, .less), PowerShell modules and manifests (.psm1, .psd1), Windows and .NET project files (.sln, .csproj, .vbproj, .vcxproj, .props, .targets, .resx, .nuspec, .manifest), other build files (.cmake, .mk, .gradle), and plain-text data (.diff, .patch, .reg, .po, .srt, .vtt, .ics), with contributions from @kailiang0120 in 1a71a4f.
• Preview PEM-armored key and certificate files (.pem, .crt, .cer, .csr, .key, .pub, .ppk, .asc) and extensionless OpenSSH key files.
• Recognize more exact filenames, including AUTHORS, CONTRIBUTING, CHANGELOG, CODEOWNERS, VERSION, Rakefile, Procfile, Justfile, Jenkinsfile, .gitmodules, and .nvmrc.
• Preview header-verified MPEG-4/QuickTime/3GPP (.mp4, .m4v, .mov, .mp4v, .3g2, .3gp, .3gp2, .3gpp), AVI (.avi), and ASF (.asf, .wmv) video containers through native Windows playback, with contributions from @tanveyhong in 2d6fb6f.

Changed

• Reveal video as soon as its verified player and preview surface are ready instead of waiting on a fixed 400 ms preroll, incorporating playback, metadata, and loading work by @tanveyhong in d9a2e1b and ef7201c.
• Retain one balanced Media Foundation platform session across hover players instead of restarting the platform for every video.

Security

• Document that key, certificate, and registry previews put secret material on the display, and that binary variants of newly eligible names still fail the content check.

Highlights

This patch shortens the preview wait and adds opt-in diagnostics for investigating Explorer performance.

Added

• Add an optional diagnostic build with correlated timing across the coordinator and contained preview worker.
• Include a PowerShell summary tool for hover-to-visible latency, lifecycle failures, and dropped diagnostic records.

Changed

• Reduce the default dwell delay to 50 ms and use a 25 ms re-show delay after leaving a preview.
• Offer 50 ms, 100 ms, and 250 ms dwell presets from the notification-area menu.
• Optimize the release executable for runtime speed while retaining full link-time optimization.

Privacy

• Keep diagnostic tracing disabled in normal release builds.
• Bound diagnostic storage and exclude file contents, file names, complete paths, credentials, and environment values.

Highlights

This patch keeps CursorPeek visible through two common Explorer hover conflicts.

Fixed

• Keep CursorPeek above a validated Explorer infotip without activating or modifying Explorer.
• Preserve an active preview while the pointer is over the part of the preview that overlaps its verified source item.

Security

• Restrict infotip handling to a visible tooltips_class32 window owned by the validated Explorer process and overlapping the active preview.
• Accept only CursorPeek's active preview root while the physical point remains inside the stored resolver-validated source rectangle. Clicks, wheel input, keyboard input, and unrelated windows still dismiss the preview.

• CycloneDX SBOM

Highlights

This release makes previews faster, more compact, and available from visible inactive Explorer windows.

Added

• Preview supported files in an unobscured Explorer window even while another application remains active.
• Carry the verified Explorer-window identity through the contained-worker protocol and revalidate the same root and active Shell view throughout preview lifetime.
• Make the repeat-preview cache configurable, with a larger 128-entry default.

Changed

• Size image previews from their natural dimensions and shrink only when they exceed the selected maximum.
• Measure text content so short files do not leave unused popup space, with metadata below both image and text previews.
• Reduce repeated-hover latency through worker prewarming, Shell-view reuse, and verified preview caching.
• Preserve the dwell deadline while the pointer moves within one Explorer item and use a brief re-show delay when moving directly to another item.

Security

• Protocol version 9 binds each product request to the exact Explorer root admitted by the coordinator. Occlusion, pointer departure, root/view replacement, destruction, hiding, or minimization still fail closed.
• Foreground changes now trigger target-context revalidation instead of weakening or discarding the Explorer identity check.

Highlights

This patch release restores the notification-area menu when CursorPeek is right-clicked.

Fixed

• Routed notification-area callbacks through CursorPeek's event loop so the tray menu opens when the icon is right-clicked.
• Used the correct mouse, keyboard, and cursor-position contracts when placing the tray menu, and returned focus to the notification area after the menu closes.
