 "safeToUpdate": "caution",
 "rationale": "The rename of the CACHE_DIR environment variable to CACHE_DIRECTORY is a breaking configuration change for any deployment that sets that variable explicitly. No database migration or other manual step is called out, but users with custom env configs must update before or immediately after upgrading to avoid misconfiguration.",
 "changelogSummary": "Calibre-Web 0.6.26 introduces multi-book editing from the book list, Instapaper support in Kobo sync, and EPUB reader improvements including a page count display, a new theme, and a back-to-library button. A notable rename affects the environment variable previously called CACHE_DIR, which is now CACHE_DIRECTORY, requiring a config update for anyone who set it explicitly. The release also patches Calibre 9 compatibility, fixes OPDS downloads in Readest on iOS and macOS, resolves several Caliblur theme issues, and closes a security gap where API keys could be exposed via config_sql.py.",
