Postmark adds its own SOC 2 Type 2 report to a run of security work.
A side-by-side editorial comparison of Misskey and Proton Bridge — release velocity, themes, recent moves, and the top alternatives to consider.
Misskey's next release cuts server memory by up to 140MB with a new start script.
Misskey, the ActivityPub social server, follows a monthly alpha-to-release cycle. The 2026.11.0 alpha adds a production start script, node ./scripts/start.mjs, that avoids leftover resident processes and cuts memory use by 70 to 140MB; official Docker images use it automatically. It also carries the improved display of quote posts from Mastodon and other software, plus a batch of deck, chat and push-notification fixes. October's 2026.10.1 moved to Sentry SDK v11.
Proton Bridge v3.27.2 adds support for the oo7 keyring on Linux.
Proton Bridge's releases in 2026 have been almost entirely maintenance: monthly vulnerability patches, Go toolchain bumps, IMAP RFC-compliance fixes and recovery from corrupted sync state files. v3.27.2 adds one item, support for the oo7 keyring service, a Rust-based Secret Service implementation used on newer Linux desktops.

Recent releases lean on operator concerns: security fixes, Sentry configuration, safe startup on bad queue config, and now memory footprint. Federation polish with non-Misskey software continues alongside, which matters for smaller self-hosted instances.
2026.11.0 is likely to go final within weeks carrying the start script, following the pattern of alphas reaching release in two to three weeks. Further memory or query-reduction work looks likely given the server fixes trimming unneeded user-data lookups.

Bridge remains a stable compatibility layer rather than a growing product. The small additions that do land are about running cleanly on more desktop environments.
Expect the next monthly security patch release; the entries show no sign of feature work.
