Covers releases 1.8.0 to 1.8.2.

Features & improvements

N/A

Fixes

• Clearer build-failure guidance. More signing, resource, dependency, licence and app-icon upload failures now receive fixed, user-safe guidance instead of a generic build-failure message.

Covers releases 1.7.0 to 1.7.8.

Features & improvements

• Easier feedback after a build. The Studio build-success screen now links directly to the in-app feedback form for bugs, feature requests and questions.
• Actionable signing failure messages. Recognised signing problems now show targeted guidance, while unrecognised failures retain the generic message.

Fixes

• Safer managed configuration. Invalid managed overrides are now rejected instead of falling back to baked documents; the previously synced library is preserved, and EMM status identifies the failing schema key without exposing submitted values, source names, IDs or URLs.
• Invalid settings are caught early. Network timeouts must be from 1 to 3600 seconds, and sync intervals from 15 minutes to 365 days; invalid build-form values are rejected instead of being silently replaced with defaults.
• More resilient saved and imported configurations. Studio now discards invalid setting values rather than crash-looping when loading or importing them.

Covers releases 1.6.0 to 1.6.1.

Features & improvements

• Safer update-code handover. Build results clearly explain that the permanent update code is required to rebuild an existing app, make downloading the app configuration the primary way to save it, and hold the APK download until the code has been saved, copied successfully or acknowledged.

Covers releases 1.5.0 to 1.5.5.

Features & improvements

• Clearer upload limits. Icon and keystore fields now show their maximum sizes, and the bulk-document drop-zone shows the per-file limit for each supported document type.
• Faster managed-configuration updates. When the app is running, a managed-configuration push now re-syncs documents and refreshes the library, branding and status in place; updates still follow the configured Wi-Fi-only rule.

Fixes

• Safer upload size enforcement. Oversized icon and keystore uploads are rejected even when their declared upload size is missing or inaccurate.
• Security settings no longer silently disable protections. Invalid rate-limit settings now stop startup instead of leaving rate limiting off, and alerting will not send its bearer token to a non-HTTPS server except loopback HTTP.

Known issues

N/A

Features & improvements

• Removed folder filter chips from the DAG Studio device preview.
• The preview now better reflects the generated app's document library behaviour, where folder membership is expressed by each document's folder assignment.

• Removed the separate Folders review cell from DAG Studio.
• Folder context now comes from the document-grouped review list, avoiding duplicate folder summaries.

Features & improvements

• Improved the DAG Studio review screen so documents appear as a scrollable, folder-grouped list.
• The review now scales better for larger document libraries and keeps the folder context visible before build.

Fixes

• Hardened the feedback endpoint against cross-site form posts.
• Feedback delivery now reports delivery failures to the user instead of accepting a message that could not be sent.
• Added coverage for feedback relay safety, sanitisation, rate limiting, and the anti-spam honeypot.

Known issues

N/A

Features & improvements

• Added an in-product feedback widget to Studio and the classic form.
• Studio includes a Feedback action in the header, with a compact fallback in the collapsed mobile menu.
• Feedback is sent through the generator service, so it works from the public /documents/ route without opening a separate contact page.

Features & improvements

• Added a Studio header home button that returns to the gen.bayton.org generators hub.
• On narrow screens, the home action appears as a full-width item in the collapsed header menu.

Features & improvements

• Studio now confirms before importing a config over an in-progress build.
• The welcome screen remains exempt because no operator-entered configuration exists there yet.

Features & improvements

• Library accent colour can now be changed at runtime through managed configuration.
• Added branding_accent so an EMM can re-tint a fielded app without rebuilding.
• Renamed the managed-config theme-mode label to match behaviour: it sets a managed default, not a hard lock.

Fixes

• Corrected documentation and generated-app descriptions for signing environment names, HEIC/HEIF caveats, config export filename, and resumable-sync integrity.

Known issues

N/A

Features & improvements

• URL document downloads now stream to disk instead of buffering the full file in memory.
• Interrupted downloads can resume when the server validator confirms the resource is unchanged.
• Document updates are written atomically so a failed update does not destroy the previous offline copy.
• Size limits are now type-aware: PDF and EPUB up to 150 MiB, other supported types up to 32 MiB.

N/A

Features & improvements

• Added EPUB support with a reflowable in-app reader.
• EPUB reader includes table of contents, font-size and line-height controls, themes, reading progress, and resume.
• EPUBs are handled with zip-slip and zip-bomb protections, XXE-hardened parsing, JavaScript disabled, and synthetic-origin WebView serving.

Fixes

N/A

Known issues

• Fixed-layout EPUBs are detected and shown best-effort.

Features & improvements

• Added bulk document upload in Studio and the classic form.
• Operators can drop multiple files, drop a folder, or browse for files/folders; supported files become built-in document sources automatically.
• Dropped folders are retained as library folders and assigned to their documents.
