The official blyg of the blygger protocol: RFCs open for comment, release announcements from every client, and technical notes. The spec itself lives at blygger.org/spec/.

Blygger Studio 0.46.3

Released 2026-10-17, the reference client. v0.46.3 on GitHub.

Migrations: none. No config change. The code is 0.46.2's, released under a new number because 0.46.2's tag could not be: the conformance-suite images that 0.46.2's new oauth-interop CI job pins by digest were deleted from GitLab's registry when GitLab rebuilt the release-v5.3.2 tag, so that commit's Check could not pass. Both images are re-pinned to the tag's current digests. If you upgraded to 0.46.2 from its tag, nothing changes but the version string.

0.46.2 — 2026-10-17 (tagged, never released)

Migrations: none. No config change.

  • OAuth clients that leave out resource now get a working token (Kyle Mathews, #66; reported as #54). A client that omits the RFC 8707 resource indicator, as generic OAuth clients and manually configured MCP proxies do, could complete the owner's consent and then fail at the token endpoint with invalid_grant. The authorization request now defaults to the node's MCP resource before login, consent and code issuance, and the consent page shows that MCP address. An explicit resource is validated as before, and the default grant cannot reach the REST API: REST clients still ask for the API resource by name. No new routes, no host-root paths. docs/oauth-interop.md and docs/issue-54-cloudflare-mcp.md have the findings and the Cloudflare portal setup.
  • Hover text on the editor toolbar (#48). The [[, ![[ and TK buttons had labels for screen readers only; each now says what it does when pointed at, and attach image does too.
  • CI: a new oauth-interop job runs MCP Inspector 2.10.1 and selected OpenID Foundation conformance modules against disposable Workers, with the package version and container digests pinned (#66).

This announcement is drafted from the release's section of CHANGELOG.md, which is where it is maintained. To comment, respond to this item from your own blyg.
