Mailu vs Session: at a glance
What is Mailu?
Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
Mailu's 2024.06 branch shipped six pinned releases in October, each tied to a single issue. Three dealt with the resolver: handling the DNSSEC KSK rollover, then making the healthcheck fail on SERVFAIL, re-shipped once. Three were webmail: Roundcube 1.6.20, mitigations for the PHP2Shell CVEs, and then the patched PHP runtime. Late September releases fixed boolean settings that could not be turned off and stale webmail sessions after switching accounts via SSO.
What is Session?
Session survived its funding scare; now Pro is on hold and Protocol v2 is the bet.
Session's 2026 started with a cofounder's appeal warning the project might not continue, followed in June by news that community support had restored its runway. Since then the feed has tracked Session Pro: release preparation in August, a proposed change to Pro's tokenomics, a beta submitted to app stores in September, then in October a pause on the Pro launch while talks with an allied privacy ecosystem continue. Infrastructure work continued, with lighter Session Node software in mid-October.

Mailu's October: patched PHP for webmail, and a resolver that reports DNS failures
◆ Current state
Mailu's 2024.06 branch shipped six pinned releases in October, each tied to a single issue. Three dealt with the resolver: handling the DNSSEC KSK rollover, then making the healthcheck fail on SERVFAIL, re-shipped once. Three were webmail: Roundcube 1.6.20, mitigations for the PHP2Shell CVEs, and then the patched PHP runtime. Late September releases fixed boolean settings that could not be turned off and stale webmail sessions after switching accounts via SSO.
◆ Where it's heading
The project remains in one-fix-per-release maintenance on the 2024.06 line, with upstream webmail and PHP security driving much of the cadence. Nothing in the entries points to a new main release.
◆ Prediction
The next releases will most likely follow upstream Roundcube or PHP security fixes, as three of the last six did.
Session
5.0COMMS
Session survived its funding scare; now Pro is on hold and Protocol v2 is the bet.
◆ Current state
Session's 2026 started with a cofounder's appeal warning the project might not continue, followed in June by news that community support had restored its runway. Since then the feed has tracked Session Pro: release preparation in August, a proposed change to Pro's tokenomics, a beta submitted to app stores in September, then in October a pause on the Pro launch while talks with an allied privacy ecosystem continue. Infrastructure work continued, with lighter Session Node software in mid-October.
◆ Where it's heading
Protocol v2, adding forward secrecy, post-quantum encryption and better linked-device handling, is now the main technical thread, with an invite-only alpha planned. Pro's monetisation model is in flux, so the revenue side remains unresolved.
◆ Prediction
Unclear whether Pro launches in its current form; the next concrete step is more likely a Protocol v2 alpha announcement.
