Mattermost ships v11.8 compliance controls amid heavy sovereign-defence content
A side-by-side editorial comparison of Mumble and SiYuan — release velocity, themes, recent moves, and the top alternatives to consider.
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.
SiYuan's 3.7.0 turns the note-taker into a scriptable, extensible platform
SiYuan is converging its long 3.7.0 dev cycle toward release. The cumulative changelog — repeated across many dev builds — centers on a kernel plugin system, a new command-line interface, configurable secrets and variables, a reworked settings UI, and a large batch of database, editor, and mobile refinements. A breaking change now requires an explicit 'serve' subcommand to run the kernel.

The same long-standing macOS notarization and gaming-overlay compatibility issues recur in every release note, with no resolution in sight.
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.
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.

A breaking change now requires an explicit 'serve' subcommand to run the kernel.
The headline direction is extensibility and automation: a plugin-capable kernel, CLI access, and secrets/variables move SiYuan from a self-contained app toward something developers can script and integrate. The breaking kernel API changes and the new serve subcommand are the cost of that platform shift. Underneath, steady editor/database hardening and broad localization continue.
Expect 3.7.0 to ship from the beta line with the plugin system and CLI as its banner features, followed by an ecosystem period of plugins and integrations building on the new kernel APIs. The repeated dev-build entries don't add direction beyond this.
