DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Storage keys added for mailboxes, file history and job drafts

Under the hood
Useful2 Signal3
Internals

New storage key types cover mailboxes, file history, job drafts and session aliases.

What

Alongside the new storage handle, key builders were added for mailbox, fileHistory, jobPins, jobDraft, bridgePointer, sessionAliases and a journal variant of transcripts, and the handle is now an explicit argument to settings writes, scheduled task enable and remove, job dispatch and respawn, MCP CLI subcommands, worktree and workflow dialogs, and the daemon's claim and adopt paths.

Evidence

sessionAliases: (e) => ({ namespace: "sessionAliases", projectKey: e })

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
