What is Bitbucket?

Bitbucket fills out Agentic Pipelines with test agents, MCP access and Merge Queue APIs.

October activity builds on the April launches. Test Optimizer and Test Cleanup agents join an improved Flaky Test Fixer, Agentic Pipelines connects to the redesigned Atlassian MCP server for Claude and Codex agents, and Merge Queues get public APIs for Standard and Premium workspaces. A visual refresh of the Pipelines list and result pages rounds out the month, with no changes to configurations.

What is Fiber?

Fiber v3 has sat in release candidate for months while v2 gets one-line patches

The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.

Bitbucket fills out Agentic Pipelines with test agents, MCP access and Merge Queue APIs.

◆ Current state

October activity builds on the April launches. Test Optimizer and Test Cleanup agents join an improved Flaky Test Fixer, Agentic Pipelines connects to the redesigned Atlassian MCP server for Claude and Codex agents, and Merge Queues get public APIs for Standard and Premium workspaces. A visual refresh of the Pipelines list and result pages rounds out the month, with no changes to configurations.

◆ Where it's heading

Pipelines continues to widen from CI into a place where agents do maintenance work, now with test upkeep as the first concrete catalog. Merge Queues is moving from a feature into something other tools can drive through the API. Atlassian's own account of daily test-coverage agents shows the pattern it wants customers to copy.

◆ Prediction

Expect further agent tasks in the same chore-focused mold. The entries do not state a general availability date for Merge Queues, so that remains unclear even though the API work points toward it.

Fiber v3 has sat in release candidate for months while v2 gets one-line patches

◆ Current state

The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.

◆ Where it's heading

v3 is the answer to Fiber's longest-standing objection, that building on fasthttp cuts a project off from the net/http middleware ecosystem. Making both handler styles native reframes Fiber as compatible rather than separate. But rc.3 dates to late 2025 and nothing newer has landed in this feed, while v2 patches keep arriving through August — a long release candidate stretch that leaves users choosing between a stable branch in pure maintenance and a v3 that has not been declared final.

◆ Prediction

The next meaningful entry is either a v3.0.0 final or a further RC; until one lands, expect the v2 line to continue receiving single-PR backports and security patches.
