Universal File Viewer 0.5.6
Release Details
UpdatedOct. 8, 2026, 6:38 p.m.
Changelog

Changed

  • Updated Flyfish File Viewer and the specialist renderer packages from 3.1.1 to 3.1.2.
  • Updated Nextcloud Router to 3.2.0, Nextcloud Vue to 9.13.1, Vue to 3.5.43, Playwright to 1.63.0, and Vite to 8.3.2, with refreshed compatible transitive dependencies.
  • Enforced patched DOMPurify 3.4.16 and KaTeX 0.18.10 versions throughout the dependency graph.
  • Kept unshipped opt-in renderers out of the generated supported-format inventory.
  • Updated the Nextcloud Playground demo to install version 0.5.6 and use Flyfish 3.1.2 samples.

Security

  • Require confirmation that custom basemap URLs and keys are public browser configuration, withhold legacy unconfirmed credentials, load geo options only for geospatial files, and remove credential-bearing console output.
  • Authorize releases using trusted signed annotated tags on protected main, build without publication credentials, and verify the approved artifact digest in a separate publication job.
  • Serialize MIME mapping, ownership, and filecache updates; detect conflicting edits and atomically replace the mapping file while preserving its permissions and ownership.
  • Confine the browser-test asset server to canonical viewer/runtime roots and limit CORS to opaque sandbox origins.

Changelog

Added

  • Added lazy, self-hosted previews for CHM help files, binary/executable inspection, Adobe and design formats, DICOM medical images, and cryptographic signature/evidence containers.

Changed

  • Updated Flyfish File Viewer from core 2.3.0/web-full 2.3.7 to 3.1.1 and refreshed the full transitive dependency lockfile.
  • Kept specialist parser workers inside the existing opaque iframe boundary by preparing their self-hosted worker sources as frame-owned blob: workers on demand.
  • Added an RTF compatibility bundle so RTF remains available with Flyfish 3.1.1's split optional capability loading.
  • Pinned patched transitive versions of adm-zip, fflate, and uuid used by the DICOM dependency stack.
  • Updated the Nextcloud Playground demo to install version 0.5.5 and use Flyfish 3.1.1 samples, including representative CHM, binary, design, DICOM, and signature files.

Changelog

Fixed

  • Added canonical MIME mappings for Flyfish 2.3.7's new FB2, HWP/HWPX, and WordPerfect extensions so supported-format generation succeeds.
  • Added regression coverage against Flyfish's live supported-extension inventory so future dependency updates fail in unit tests before generated format files become stale.

UpdatedJuly 23, 2026, 10:59 p.m.
Changelog

Added

  • Added legacy PowerPoint (.ppt) and tab-separated value (.tsv) previews to the generated format settings and Nextcloud MIME mappings.

Changed

  • Updated the bundled Flyfish File Viewer packages from 2.1.23 to 2.2.3, including the self-hosted PPT, OCCT model, PDF font, CAD, and EPUB runtime updates.
  • Run the new STEP/IGES/BREP parser worker inside the existing opaque sandbox worker boundary.
  • Use the legacy PPT renderer's asynchronous direct path inside the opaque iframe because its integrity-verifying Worker requires Web Crypto, which is unavailable to opaque Chromium workers.

Changelog

Changed

  • Replaced raw MIME controls with human-readable extension groups backed by stable app format identifiers.
  • Resolve Viewer registrations from Nextcloud's effective extension-to-MIME mapping, including administrator overrides, and migrate existing disabled-MIME preferences.
  • Register fallback extension-to-MIME mappings for every Flyfish-supported format while preserving administrator and future Nextcloud core mappings.
  • Label MIME-colliding format groups with explicit extensions such as DOC/DOT and C/CC instead of generic MIME descriptions.
  • Show Markdown alongside source and text formats in the Code and text section.
  • Sort format names alphabetically within each settings section.
  • Remove MIME-registration bookkeeping when the app is disabled or uninstalled while preserving administrator mappings and user format preferences.
  • Avoid racing Nextcloud's queued Viewer registration when promoting Universal File Viewer ahead of built-in handlers.

Universal File Viewer 0.5.6
Release Details
UpdatedOct. 8, 2026, 6:38 p.m.
Changelog

Changed

  • Updated Flyfish File Viewer and the specialist renderer packages from 3.1.1 to 3.1.2.
  • Updated Nextcloud Router to 3.2.0, Nextcloud Vue to 9.13.1, Vue to 3.5.43, Playwright to 1.63.0, and Vite to 8.3.2, with refreshed compatible transitive dependencies.
  • Enforced patched DOMPurify 3.4.16 and KaTeX 0.18.10 versions throughout the dependency graph.
  • Kept unshipped opt-in renderers out of the generated supported-format inventory.
  • Updated the Nextcloud Playground demo to install version 0.5.6 and use Flyfish 3.1.2 samples.

Security

  • Require confirmation that custom basemap URLs and keys are public browser configuration, withhold legacy unconfirmed credentials, load geo options only for geospatial files, and remove credential-bearing console output.
  • Authorize releases using trusted signed annotated tags on protected main, build without publication credentials, and verify the approved artifact digest in a separate publication job.
  • Serialize MIME mapping, ownership, and filecache updates; detect conflicting edits and atomically replace the mapping file while preserving its permissions and ownership.
  • Confine the browser-test asset server to canonical viewer/runtime roots and limit CORS to opaque sandbox origins.

Changelog

Added

  • Added lazy, self-hosted previews for CHM help files, binary/executable inspection, Adobe and design formats, DICOM medical images, and cryptographic signature/evidence containers.

Changed

  • Updated Flyfish File Viewer from core 2.3.0/web-full 2.3.7 to 3.1.1 and refreshed the full transitive dependency lockfile.
  • Kept specialist parser workers inside the existing opaque iframe boundary by preparing their self-hosted worker sources as frame-owned blob: workers on demand.
  • Added an RTF compatibility bundle so RTF remains available with Flyfish 3.1.1's split optional capability loading.
  • Pinned patched transitive versions of adm-zip, fflate, and uuid used by the DICOM dependency stack.
  • Updated the Nextcloud Playground demo to install version 0.5.5 and use Flyfish 3.1.1 samples, including representative CHM, binary, design, DICOM, and signature files.

Changelog

Fixed

  • Added canonical MIME mappings for Flyfish 2.3.7's new FB2, HWP/HWPX, and WordPerfect extensions so supported-format generation succeeds.
  • Added regression coverage against Flyfish's live supported-extension inventory so future dependency updates fail in unit tests before generated format files become stale.

UpdatedJuly 23, 2026, 10:59 p.m.
Changelog

Added

  • Added legacy PowerPoint (.ppt) and tab-separated value (.tsv) previews to the generated format settings and Nextcloud MIME mappings.

Changed

  • Updated the bundled Flyfish File Viewer packages from 2.1.23 to 2.2.3, including the self-hosted PPT, OCCT model, PDF font, CAD, and EPUB runtime updates.
  • Run the new STEP/IGES/BREP parser worker inside the existing opaque sandbox worker boundary.
  • Use the legacy PPT renderer's asynchronous direct path inside the opaque iframe because its integrity-verifying Worker requires Web Crypto, which is unavailable to opaque Chromium workers.

Changelog

Changed

  • Replaced raw MIME controls with human-readable extension groups backed by stable app format identifiers.
  • Resolve Viewer registrations from Nextcloud's effective extension-to-MIME mapping, including administrator overrides, and migrate existing disabled-MIME preferences.
  • Register fallback extension-to-MIME mappings for every Flyfish-supported format while preserving administrator and future Nextcloud core mappings.
  • Label MIME-colliding format groups with explicit extensions such as DOC/DOT and C/CC instead of generic MIME descriptions.
  • Show Markdown alongside source and text formats in the Code and text section.
  • Sort format names alphabetically within each settings section.
  • Remove MIME-registration bookkeeping when the app is disabled or uninstalled while preserving administrator mappings and user format preferences.
  • Avoid racing Nextcloud's queued Viewer registration when promoting Universal File Viewer ahead of built-in handlers.

Universal File Viewer 0.5.6
Release Details
UpdatedOct. 8, 2026, 6:38 p.m.
Changelog

Changed

  • Updated Flyfish File Viewer and the specialist renderer packages from 3.1.1 to 3.1.2.
  • Updated Nextcloud Router to 3.2.0, Nextcloud Vue to 9.13.1, Vue to 3.5.43, Playwright to 1.63.0, and Vite to 8.3.2, with refreshed compatible transitive dependencies.
  • Enforced patched DOMPurify 3.4.16 and KaTeX 0.18.10 versions throughout the dependency graph.
  • Kept unshipped opt-in renderers out of the generated supported-format inventory.
  • Updated the Nextcloud Playground demo to install version 0.5.6 and use Flyfish 3.1.2 samples.

Security

  • Require confirmation that custom basemap URLs and keys are public browser configuration, withhold legacy unconfirmed credentials, load geo options only for geospatial files, and remove credential-bearing console output.
  • Authorize releases using trusted signed annotated tags on protected main, build without publication credentials, and verify the approved artifact digest in a separate publication job.
  • Serialize MIME mapping, ownership, and filecache updates; detect conflicting edits and atomically replace the mapping file while preserving its permissions and ownership.
  • Confine the browser-test asset server to canonical viewer/runtime roots and limit CORS to opaque sandbox origins.

Changelog

Added

  • Added lazy, self-hosted previews for CHM help files, binary/executable inspection, Adobe and design formats, DICOM medical images, and cryptographic signature/evidence containers.

Changed

  • Updated Flyfish File Viewer from core 2.3.0/web-full 2.3.7 to 3.1.1 and refreshed the full transitive dependency lockfile.
  • Kept specialist parser workers inside the existing opaque iframe boundary by preparing their self-hosted worker sources as frame-owned blob: workers on demand.
  • Added an RTF compatibility bundle so RTF remains available with Flyfish 3.1.1's split optional capability loading.
  • Pinned patched transitive versions of adm-zip, fflate, and uuid used by the DICOM dependency stack.
  • Updated the Nextcloud Playground demo to install version 0.5.5 and use Flyfish 3.1.1 samples, including representative CHM, binary, design, DICOM, and signature files.

Changelog

Fixed

  • Added canonical MIME mappings for Flyfish 2.3.7's new FB2, HWP/HWPX, and WordPerfect extensions so supported-format generation succeeds.
  • Added regression coverage against Flyfish's live supported-extension inventory so future dependency updates fail in unit tests before generated format files become stale.

Changelog

Added

  • Added legacy PowerPoint (.ppt) and tab-separated value (.tsv) previews to the generated format settings and Nextcloud MIME mappings.

Changed

  • Updated the bundled Flyfish File Viewer packages from 2.1.23 to 2.2.3, including the self-hosted PPT, OCCT model, PDF font, CAD, and EPUB runtime updates.
  • Run the new STEP/IGES/BREP parser worker inside the existing opaque sandbox worker boundary.
  • Use the legacy PPT renderer's asynchronous direct path inside the opaque iframe because its integrity-verifying Worker requires Web Crypto, which is unavailable to opaque Chromium workers.

Changelog

Changed

  • Replaced raw MIME controls with human-readable extension groups backed by stable app format identifiers.
  • Resolve Viewer registrations from Nextcloud's effective extension-to-MIME mapping, including administrator overrides, and migrate existing disabled-MIME preferences.
  • Register fallback extension-to-MIME mappings for every Flyfish-supported format while preserving administrator and future Nextcloud core mappings.
  • Label MIME-colliding format groups with explicit extensions such as DOC/DOT and C/CC instead of generic MIME descriptions.
  • Show Markdown alongside source and text formats in the Code and text section.
  • Sort format names alphabetically within each settings section.
  • Remove MIME-registration bookkeeping when the app is disabled or uninstalled while preserving administrator mappings and user format preferences.
  • Avoid racing Nextcloud's queued Viewer registration when promoting Universal File Viewer ahead of built-in handlers.
