What is Fission?
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.
What is Render?
Render swaps static keys for federated identity and opens its control plane to coding agents.
Render's last month splits cleanly in two. Managed OIDC went generally available for AWS on Pro workspaces and then extended to Anthropic and OpenAI, letting services authenticate to those providers without stored credentials. In parallel the Render MCP server gained a trigger_deploy tool and OAuth support for Claude Code, Codex, and Cursor. Build infrastructure moved to faster CPU and disk, cutting median build time 40% across all runtimes.

Fission's release feed carries only RC tags, and none of them say what shipped
◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Render
6.3INFRA · APIS
Render swaps static keys for federated identity and opens its control plane to coding agents.
◆ Current state
Render's last month splits cleanly in two. Managed OIDC went generally available for AWS on Pro workspaces and then extended to Anthropic and OpenAI, letting services authenticate to those providers without stored credentials. In parallel the Render MCP server gained a trigger_deploy tool and OAuth support for Claude Code, Codex, and Cursor. Build infrastructure moved to faster CPU and disk, cutting median build time 40% across all runtimes.
◆ Where it's heading
Render is removing long-lived secrets from the platform and replacing them with short-lived federated identity, starting with the cloud provider and now covering model providers. At the same time it is making the control plane addressable by agents rather than only by humans: the MCP server can authenticate through the same OAuth flow the coding tools already use, and it can now perform a deploy rather than just read state. Read the two threads together and the platform is being shaped for workloads written and operated by agents that should never hold a static key. The build-time work is table stakes maintenance underneath that.
◆ Prediction
Expect the MCP server's write surface to keep expanding past trigger_deploy into service and environment management, since OAuth is now in place to scope it. Extending managed OIDC to more third-party providers beyond AWS, Anthropic, and OpenAI is the obvious continuation of the credential work.
