v1.2.12

Stats uploads now use WebDAV write locks, verified temporary files, backups, and MOVE replacement to prevent interrupted transfers from truncating the live stats file.

• Reconcile complete history, including older sessions and updated durations.
• Repair missing book page counts and merge duplicate reading events so imported stats appear correctly.
• Preserve the existing cloud format. Update every device to protect all uploads; the server must support WebDAV write locks and MOVE.

Validated with Lua tests covering interrupted uploads, replacement failures, locks, competing writers, and history merging; Lua syntax checks; and live phone/Boox sync verification.

Syncest v1.2.11

Syncest now keeps its local files in koreader/settings/syncest/, with temporary sync files in cache/tmp/, so the settings directory no longer fills up with loose sync files.

• Migrate the existing library database, covers, thumbnails, updater cache, and legacy debug log on startup.
• Remove temporary downloads after network errors and clean abandoned transfer/result files older than 24 hours.
• Preserve shared KOReader settings, statistics, vocabulary, and book sidecars.

Cloud paths and sync formats are unchanged; devices on older Syncest versions can continue syncing together. Downgrading this device requires restoring the old local storage layout.

Validation: Lua syntax checks and storage migration/cleanup regression checks passed.

Syncest v1.2.10

• Prevent a queued resume progress pull from running again after the authoritative book-open pull.
• Fix a full book-library push crash during embedded metadata enrichment.
• Keep the Syncest submenu attached when Zen UI rebuilds its long-press book context menu.

Syncest v1.2.9

• Restore WebDAV syncing on KOReader versions that removed the legacy apps/cloudstorage/webdavapi module.
• Fall back to Syncest's own WebDAV transport while retaining the legacy KOReader transport on older versions.

Syncest v1.2.8

• Restore compatibility with KOReader 2026.07 and newer by using the replacement Cloud storage plugin API.
• Keep compatibility with older KOReader versions through the legacy SyncService fallback.

Syncest v1.2.7

• Push chapter-completion progress immediately instead of holding it behind the automatic page-turn cooldown.
• Keep chapter and manual progress pushes on the same complete progress-and-history operation.
• Refresh filename-derived catalog titles and authors from embedded EPUB/PDF metadata during bulk library pushes.

Syncest v1.2.6

• Acknowledge automatic chapter progress as soon as the latest reading position is durable, without waiting for progress-history bookkeeping.
• Keep manual progress checkpoints strict: success still waits until both current progress and history are saved.

Syncest v1.2.5

Stable cloud titles

• Preserve cloud book titles across page changes and delayed ZenUI refreshes with title-named, hash-isolated rendered thumbnails.

Correct embedded metadata

• Extract embedded title, author, and metadata during background Push Books when KOReader sidecar metadata is unavailable.
• Publish canonical EPUB/PDF metadata instead of deriving cloud titles from filenames.
• Keep stored metadata authoritative without display-time title stripping.

Syncest v1.2.4

Faster manual progress pushes

• Reduce normal progress-history bookkeeping to one read and one write.
• Skip redundant WebDAV folder probes and repair the hierarchy only after a direct write fails.
• Persist remote device-registration confirmation, while automatically registering again after a cloud wipe.

Reliable completion notification

• Show the manual success notification immediately after both current progress and its history checkpoint are durable.
• Report a failed manual push if the requested history checkpoint could not be saved, so the success notification remains safe to rely on before exiting KOReader.

Syncest v1.2.3

Cloud library cover reliability

• Render cached cloud and grouped-library covers through real PNG paths so Zen UI no longer substitutes generated placeholders.
• Reuse cloud cover art for local books whose embedded covers cannot be extracted.
• Materialize group mosaics before rendering while preserving correct titles instead of cache hashes.
• Normalize local and cloud thumbnail sizing in list view.

Mobile push reliability

• Increase WebDAV transfer timeouts for books and covers on high-latency mobile connections.
• Show verification progress while determining which books actually require uploading.

Library grouping

• Add an explicit None grouping option and make the flat library the default.
• Keep Authors and Series grouping.
• Remove the unused legacy Groups option.
