Reikai 0.4.1
Oct 13, 2026
Highlights
A fix release carrying Mihon v0.21.2's fixes, applied to novels too where they fit. The most important one lets an update from 0.3.2 or earlier finish on a library holding duplicate rows or a damaged index, where it could fail before. Sites behind Cloudflare also cope better: several requests at once wait for one challenge, and logins and searches that post to a site get past it.
Changes marked (from Mihon) come from upstream Mihon, which Reikai is built on.
Reader
Fixed
- With wide-page splitting on, the second half of a split page no longer lands in the wrong chapter (from Mihon). Upstream: mihon 3156b4a1c.
- Tapping the long strip reader as it closes no longer crashes the app (from Mihon). Upstream: mihon c371d6331.
Browse & sources
Fixed
- Several requests to a Cloudflare-protected site at once now wait for one challenge instead of each opening a WebView (from Mihon). A request made from inside another one no longer stalls the site either. Upstream: mihonapp/mihon#3858.
- Logins and searches that post to a Cloudflare-protected site now get past its challenge, and if it can't be cleared, Open in WebView shows the site's home page (partly from Mihon). Upstream: mihonapp/mihon#3909.
- Opening the filters of a manga extension or novel plugin with an invalid filter no longer crashes the app (from Mihon). Upstream: mihon c9e1b6e96.
Tracking
Fixed
- The start date sent when binding a tracker to a manga or novel is no longer shifted by your time zone, which could move it a day (from Mihon). Upstream: mihonapp/mihon#4049.
- Comick tracker progress no longer shows long decimals like 35.019996643066406 (from Mihon). Upstream: mihonapp/mihon#4090.
Downloads & extensions
Fixed
- Some manga chapters downloaded before 0.4.0 show as downloaded again (from Mihon). These are chapters whose name starts with a space or dot, runs long, or names its group with letters outside basic English. Upstream: mihon f0f1e4de5.
- Installing an extension on a device with no install confirmation screen now fails with a message instead of crashing the app (from Mihon). Upstream: mihon 2df48e19a.
Backup & restore
Fixed
- A backup file that was cut short now reads as invalid instead of failing with a raw error (from Mihon). Leaving the restore screen while it checks a file no longer reports the file as unreadable. Upstream: mihonapp/mihon#3850.
App
Fixed
- Updating from 0.3.2 or earlier no longer fails when the database holds duplicate manga or novel history, tracking, update-error or merge-group rows, or a damaged index (partly from Mihon). Upstream: mihon ea2b73ad7.
- A back gesture on a screen that has already closed no longer crashes the app (from Mihon). Upstream: mihon 43de88c71.
Other
- Paging updated to 3.5.3 (from Mihon). Upstream: mihonapp/mihon#4099.
