What is Linear?

Linear Agent is becoming the product's primary surface, not a feature.

Linear is restructuring itself around Linear Agent. In the last six weeks the agent has gained MCP tool access, codebase reading via the GitHub integration, an autonomous request-filing mode in Slack, and presence inside Microsoft Teams and per-project Slack channels. The traditional Linear UI is increasingly the destination the agent acts on, not the place users live in.

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.

Linear Agent is becoming the product's primary surface, not a feature.

◆ Current state

Linear is restructuring itself around Linear Agent. In the last six weeks the agent has gained MCP tool access, codebase reading via the GitHub integration, an autonomous request-filing mode in Slack, and presence inside Microsoft Teams and per-project Slack channels. The traditional Linear UI is increasingly the destination the agent acts on, not the place users live in.

◆ Where it's heading

The work surface is shifting outward — Slack, Teams, and external MCP-served tools — while the agent does round-tripping back into Linear's data model. Code Intelligence connects the agent to engineering context that previously required a human in the loop, and the new Releases feature extends the system past planning into deployment state. Linear is positioning the agent as the orchestration layer for a small engineering org's full delivery cycle, not just an assistant inside a PM tool.

◆ Prediction

Expect deeper code-review and PR-authoring capabilities on top of Code Intelligence, plus more autonomous agent behavior in triage that turns customer-request signals into prioritized work without a human writing the spec.

2.5

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.
