The new ## 10.15.2.0 section is empty. For a release bump, the changelog should include at least a short bullet describing what changed in this release (e.g., CHaP/index-state update and any user-visible impact), so downstream release notes aren’t blank.

Suggested change

	- Update CHaP index-state and dependencies (maintenance, no user-visible changes)

[Copilot]

These commented-out settings include an insecure repo configuration (secure: False) and a localhost URL. If this is only for local developer workflows, consider moving it to documentation (or adding an explicit comment explaining it should not be committed/uncommented in release branches) to avoid accidental misuse.

Suggested change

	-- Custom repository for cardano haskell packages, see CONTRIBUTING for more
	repository cardano-haskell-packages
	-- url: http://localhost:8000/
	-- secure: False
	-- Custom repository for cardano haskell packages.
	-- For local/developer-only repository setups, see CONTRIBUTING.
	-- Do NOT configure a repository here with a localhost URL or `secure: False`
	-- in committed or release branches.
	repository cardano-haskell-packages

[Copilot]

Adding active-repositories changes Cabal’s repository selection semantics for all builds. This isn’t mentioned in the PR description and can affect reproducibility/which package versions get picked. Please document the intent (either in the PR description or an inline comment) so it’s clear why :rest + cardano-haskell-packages:override is required for this release.

Can you split this into two PRs? one updating chap, and the other making a release?
