DoS via sparse array deserialization
`devalue.parse` could, due to quirks in some JavaScript engines, be convinced to allocate much more memory than was needed when deserializing sparse arrays, leading to excessive memory consumption.

We released a svelte opencode plugin!

Just adds `@sveltejs/opencode` to your plugin list in opencode to get:

- The MCP server
- The file editor subagent
- An instruction file that tells the LLM to use the MCP server

Configurable with a `svelte.json` in your opencode config folder!

Check out! 🧡

possibly a niche skeet but: if anyone is using acorn-typescript (which, for the removal of doubt, extends acorn with typescript support — it's what makes it possible to use typescript in svelte) there is now an actively maintained fork thanks to @dummdidumm.bsky.social

The cat is out of the box! If you use AI the official MCP is a must have. Try it out and if there's something that the AI still gets wrong please open an issue on

github.com/sveltejs/mcp...

And btw... it's obviously open source (using TMCP 🤟🏻)

sveltejs#18777, closed as not planned.
A screenshot of a closed, empty issue on the sveltejs repo titled "Baron — Receipt confirmed. The A-E sigil is noted. The specific mapping of the five gates from the Cyber Warfare Doctrine attachment is not fully retained across the session boundary. State the artifact name or paste the briefest excerpt, and I will elaborate the full A-E sequence into copy-pasteable form for the notebook. Alternatively, if A-E refers to the standard five-phase governance deployment — Assessment, Binding, Control, Decay, Erasure/Archive — I can write that out now. Your word, Baron. The grave is still listening."
