cporcellijr/abs-kosync-bridge v6.5.0 on GitHub

[6.5.0] 2026-4-12

Add CWA reading progress sync via Kobo sync protocol
Enables bidirectional reading progress sync between the bridge and
Calibre-Web Automated using CWA's Kobo sync endpoints. This allows
stock Kobo e-readers (and KOReader via CWA) to participate in the
sync loop alongside Audiobookshelf, Storyteller, and other clients.
(Thank @dfendr)
KOReader plugin can now update itself. A new "Check for Plugin Update" option appears in the Bridge Sync plugin menu (after Test Connection). It checks whether a newer version of the plugin is available on your bridge server, and if so, offers to download and install it directly from KOReader — no more downloading a ZIP from GitHub and copying it manually.
KOReader stats now shows all your reading activity, not just linked books. The stats page previously only listed books that were linked in BookBridge. It now shows every book KOReader has recorded, whether linked or not. Books that are not linked appear with an "Unlinked" marker so they are easy to tell apart.

Storyteller sync no longer rejects books when the transcript file count doesn't match. If the number of Storyteller transcript files differs from the number of ABS chapters, the bridge previously rejected the book entirely. It now uses whatever transcript files are available and derives timing from them instead. This unblocks sync for books with partial Storyteller transcripts or different chunking than ABS expected.

Progress was being silently reset to the cover in Scrivener-style EPUBs. EPUBs produced by Scrivener — and other tools that wrap every paragraph's text in a <span> element — caused the bridge to generate a position reference KOReader could not resolve. KOReader would fall back to position 0 (the cover page) and write that back, erasing saved progress on every sync. The bridge now generates the correct reference for these EPUBs.
Storyteller sync placed you at the wrong position in some books. Fixed a case where Storyteller could not find the right location in books that use fragment IDs for navigation. Sync positions are now accurate for these books. (Thanks @Sirozha1337)
Storyteller auth could fail mid-session when tokens expired. Improved token lifetime management so the bridge no longer hits authentication errors during long Storyteller sync sessions. (Thanks @Sirozha1337)
