Mumble vs BookStack: at a glance
What is Mumble?
Mumble closes out the 1.5 series with another stable patch while 1.6.x waits in the wings.
Mumble is in late-stage maintenance on the 1.5 series, with v1.5.901 landing as the fourth stable patch since 1.5.634 shipped in May 2024. A 1.6.x release candidate appeared in March 2026, kicking off the project's next major branch in parallel. The same long-standing macOS notarization and gaming-overlay compatibility issues recur in every release note, with no resolution in sight.
What is BookStack?
BookStack's release stream is mostly security patches — five in three months, all responsibly disclosed.
BookStack is in a heavy security-patching phase on the 26.03 line, with five point releases since mid-March covering MFA brute-force, attachment permissions, webhook URL validation, registration role escalation, and hidden-page leakage. Every fix names the external researcher who reported it. Outside the security train, the v26.03 minor itself was the last meaningful feature release, shipping a theme-module reorganization and SMTP HELO change.
Mumble vs BookStack: editorial side-by-side
Mumble
2.5COLLAB
Mumble closes out the 1.5 series with another stable patch while 1.6.x waits in the wings.
◆ Current state
Mumble is in late-stage maintenance on the 1.5 series, with v1.5.901 landing as the fourth stable patch since 1.5.634 shipped in May 2024. A 1.6.x release candidate appeared in March 2026, kicking off the project's next major branch in parallel. The same long-standing macOS notarization and gaming-overlay compatibility issues recur in every release note, with no resolution in sight.
◆ Where it's heading
The project is gradually winding down the 1.5 line while 1.6.x stabilizes, running both branches simultaneously rather than forcing users onto an unfinished new series. Release cadence is months between stable patches and has held that way for years. Long-running platform issues (macOS signing, anti-cheat overlay blocks) continue to dog every release, suggesting maintainers have effectively conceded that ground.
◆ Prediction
Expect one or two more 1.5.x stable patches before 1.6.x reaches its own first stable. The same known-issues list will almost certainly carry into the 1.6.x line.
BookStack
5.0COLLAB
BookStack's release stream is mostly security patches — five in three months, all responsibly disclosed.
◆ Current state
BookStack is in a heavy security-patching phase on the 26.03 line, with five point releases since mid-March covering MFA brute-force, attachment permissions, webhook URL validation, registration role escalation, and hidden-page leakage. Every fix names the external researcher who reported it. Outside the security train, the v26.03 minor itself was the last meaningful feature release, shipping a theme-module reorganization and SMTP HELO change.
◆ Where it's heading
Expect the patch cadence to slow as the surfaced classes of vulnerabilities (auth, permissions, content filtering) stabilize, with the next minor likely concentrating on the theme-module API now that 26.03 has established the modules/ directory convention. The project's responsible-disclosure pipeline appears active and productive — multiple researchers, public credit, clear advisories — which is itself a competitive signal in the self-hosted wiki space.
◆ Prediction
A 26.03.6 within four weeks is likely given the current cadence, probably another dependency-bump rollup. The next minor (26.06 or 26.09 depending on the release calendar) will probably formalize the theme-modules surface and start adding API documentation for it.
