The 200ms Blocks (Denim) changelog entry referenced Flashblocks only as a contrast and left the deprecation implicit. Add a dedicated alert-style callout (BDS orange, left accent bar, "Deprecation Notice" label) stating directly that Flashblocks will be deprecated as part of this release, since native 200ms blocks deliver the same sub-second confirmation experience on the canonical chain. Also bump lastUpdated.

What
Updates the 200ms Blocks (Denim) changelog entry so the Flashblocks deprecation is stated directly rather than left implicit.
Previously the entry referenced Flashblocks only as a contrast — "Unlike Flashblocks, which expose sub-second updates while building one block…" — without saying Flashblocks is going away. It now adds:

lastUpdatedto2026-08-10.Why
The deprecation is a material consequence of shipping native 200ms blocks and should be called out explicitly for app developers, RPC/indexing providers, and node operators who rely on the Flashblocks WebSocket stream.
Scope
Single-file copy change in
app/upgrades/data/changes.ts(base-0010). No behavior changes.
