Mumble closes out the 1.5 series with another stable patch while 1.6.x waits in the wings.

voice-chatopen-sourcelow-latencymajor-versionmaintenancegaming
◆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.

◆Recent moves

    Mumble 1.5.901 ships as the fourth stable of the 1.5 line

    The fourth stable of the 1.5 series, continuing the slow but steady patch cadence Mumble has held since 1.5.634. The notes again call out the same long-standing macOS notarization and gaming-overlay compatibility issues, with detail offloaded to the blog announcement.

    Scraper artifact (no release content)

    This entry is a scraping artifact from a GitHub user profile rather than an actual Mumble release. The only real signal in this date range is the 1.6.x RC arriving the day before.

    Mumble 1.6.x release candidate opens the next major series

    ⚡ SPARK

    The first public step toward Mumble 1.6.x, shipping as an RC almost two years after the 1.5 series reached stable. The notes are brief and the known-issues list is the same one that has trailed the project for years, so this is about kicking off the next major branch rather than fixing platform pain.

    Mumble 1.5.857 ships as the third stable of the 1.5 line

    Third stable of the 1.5 series, continuing the project's slow patch rhythm. As with adjacent releases, the public notes don't enumerate user-visible changes, leaving the practical impact for anyone not following the commit log to guesswork.

    Mumble 1.5.735 ships as the second stable of the 1.5 line

    Second stable of the 1.5 series, roughly six months after 1.5.634 hit. The release-notes pattern is already set: brief acknowledgement plus the recurring known-issues list, with detail offloaded to the blog announcement.

    Mumble 1.5 reaches first stable after two years in RC

    ⚡ SPARK

    The first stable cut of the 1.5 series, arriving almost two years after 1.4.287 and following three RCs across early 2024. This is the moment self-hosted server operators waiting for a sanctioned upgrade path got the green light.
