BookStack vs Paperless-ngx: 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 Paperless-ngx?
Paperless-ngx shipped seven releases in October, two of them for security
Paperless-ngx ran from 3.3.0 to 3.4.1 in October. 3.3.0 added stored barcode contents and more control over LLM requests, 3.3.2 fixed a reported security issue, and 3.3.4 updated dependencies for the eMudhra CA incident plus Pillow and aiohttp vulnerabilities. 3.4.0 brought custom fields in workflow title templates, relative-date custom field queries, skipping local 2FA for trusted OIDC logins, poppler thumbnails and markdown in AI chat. The other releases were fixes, many around document versions and search.

◆ 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.

5.0COLLAB
Paperless-ngx shipped seven releases in October, two of them for security
◆ Current state
Paperless-ngx ran from 3.3.0 to 3.4.1 in October. 3.3.0 added stored barcode contents and more control over LLM requests, 3.3.2 fixed a reported security issue, and 3.3.4 updated dependencies for the eMudhra CA incident plus Pillow and aiohttp vulnerabilities. 3.4.0 brought custom fields in workflow title templates, relative-date custom field queries, skipping local 2FA for trusted OIDC logins, poppler thumbnails and markdown in AI chat. The other releases were fixes, many around document versions and search.
◆ Where it's heading
The AI features introduced in 3.x are being refined rather than expanded, while workflows and search get steady quality-of-life work.
◆ Prediction
Another 3.4.x patch for UI regressions is likely, following the 3.3.x pattern of several fix releases after each minor.
