BookStack vs Prowlarr: at a glance
What is BookStack?
BookStack's first feature release since May requires an APP_KEY and needed two quick patches
After four months of security patches on the 26.05 line, BookStack shipped v26.09 in late September: an interface layout system with theme support, API search within a book or chapter, a page scroll indicator, changelog messages on page API writes, and password changes that require the current password. It also stopped falling back to a default APP_KEY. Two patches followed within a month, one checking ZIP imports' real uncompressed size and one fixing comment and attachment exposure around the recycle bin and drafts.
What is Prowlarr?
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.

◆ Current state
After four months of security patches on the 26.05 line, BookStack shipped v26.09 in late September: an interface layout system with theme support, API search within a book or chapter, a page scroll indicator, changelog messages on page API writes, and password changes that require the current password. It also stopped falling back to a default APP_KEY. Two patches followed within a month, one checking ZIP imports' real uncompressed size and one fixing comment and attachment exposure around the recycle bin and drafts.
◆ Where it's heading
Security hardening keeps setting the cadence even after a feature release, with researcher reports credited in most patches. The new layout system opens the UI to customization through the theme system.
◆ Prediction
Further 26.09.x security releases are likely given the steady run of researcher reports; the entries give no date for the next feature release.
Prowlarr
5.0COLLAB
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
◆ Current state
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.
◆ Where it's heading
Security settings that limit which hosts and networks can reach the app are the main thread since September, rolled out in step with Lidarr. Indexer definitions keep getting small compatibility fixes.
◆ Prediction
More indexer-level fixes and Allowed Hosts follow-ups are likely in 2.7 patches.
