Skipper
Skipper fixes two silent data-loss bugs — body truncation on large requests and multi-value header drops.
A side-by-side editorial comparison of Fission and GitHub — release velocity, themes, recent moves, and the top alternatives to consider.
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
GitHub turns Copilot into an org-wide default, adds memory to agentic security fixes.
GitHub is shipping Copilot capabilities at a pace that makes the product unrecognizable from a year ago. This week alone: Claude Opus joined the model roster, local sandboxing landed in the Copilot app, agentic autofix gained persistent Memory integration, and enterprise Copilot features were switched to opt-out by default. GitHub is no longer selling an AI assistant — it is installing an agent layer across every developer workflow.

What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.
GitHub is shipping Copilot capabilities at a pace that makes the product unrecognizable from a year ago. This week alone: Claude Opus joined the model roster, local sandboxing landed in the Copilot app, agentic autofix gained persistent Memory integration, and enterprise Copilot features were switched to opt-out by default. GitHub is no longer selling an AI assistant — it is installing an agent layer across every developer workflow.
The product is converging on a fully agentic architecture where Copilot agents carry memory across sessions, execute in isolated local sandboxes, and coordinate work across Slack, Teams, and IDEs without requiring a developer to context-switch. The default-on enterprise policy is the distribution play: adoption no longer requires a decision, it requires an explicit reversal.
Copilot Memory will expand beyond security autofix into code review and issue triage agents. The multi-model roster — currently Claude Opus plus GitHub's own models — will grow as a platform differentiator, with model selection becoming a team-level or repo-level policy rather than a user preference.
