Daily beta build tags (e.g. v0.2.3b1-daily.20260316) were not detected
as prereleases because parse_version() only checked the last
dot-separated segment for letters. The daily date suffix is purely
numeric, so it passed the stable release check. Now checks the entire
version string for prerelease markers.
parse_version() misclassified "0.2.2b4-daily.20260313" as a release
because the daily suffix made the last dot-segment ("20260313") contain
no alpha chars, bypassing prerelease detection. Strip -daily.YYYYMMDD
suffix before parsing so daily builds compare as their base beta version.
Users on the Docker `latest` tag were seeing update notifications for beta
releases (e.g. v0.2.1b) they couldn't install. The update checker now fetches
/releases instead of /releases/latest and filters by parse_version() prerelease
detection. A new toggle in Settings (default: off) lets users opt in to beta
notifications.
Backend /updates/check endpoint now returns early without calling
GitHub API when check_updates is disabled. Settings page no longer
auto-fetches update status when the setting is off. Printer card
firmware badge falls back to showing the current version from MQTT
instead of disappearing when firmware update checks are disabled.
The CodeQL cleanup in "Housekeeping" (2b11efd) bulk-narrowed except
clauses across 50+ files, breaking FTP uploads on ALL printer models.
ftplib.error_perm (550 errors) is not a subclass of ftplib.error_reply,
so diagnose_storage() CWD failures escaped the handler and prevented
STOR from ever executing — causing 100% upload failure and HTTP 500s
on /api/v1/archives/{id}/reprint and /api/v1/library/files/{id}/print.
FTP fixes:
- Remove diagnose_storage() from upload hot path
- Change all except (OSError, ftplib.error_reply) to
except (OSError, ftplib.Error) across bambu_ftp.py
Exception handling reverts (9 files):
- Revert narrowed except clauses back to except Exception in route
handlers and service code where broad catches are intentional
defensive programming (archive parsing, HTTP clients, 3MF/ZIP
processing, Home Assistant, firmware checks)
- Keep narrow exceptions only where safe (single-op blocks like
int(), file.unlink(), socket.close())
- Remove unused XMLParseError imports from archive.py, threemf_tools.py
Version system:
- Add 4-segment version support (e.g. 0.1.8.1) for patch releases
- Bump version to 0.1.8.1
