chore: update change log
What changed, and why it matters
This commit only edits the project's changelog text. It rewrites the release notes for version 3.0.2, removing detailed bug-fix descriptions and replacing them with a shorter note about Zcash Ironwood support. No source code, build scripts, or firmware logic is changed, so this commit by itself does not introduce, fix, or alter any security behavior in the product.
No security action is required for this commit. If the removed bug-fix entries describe issues that were fixed in earlier commits, review those specific commits for security relevance rather than this documentation-only change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff is limited to two Markdown changelog files (CHANGELOG.md and CHANGELOG-ZH.md). It removes the ‘Unreleased’ section and its six listed Zcash bug fixes, and adds a ‘3.0.2 (2026-07-24)’ section with a compatibility warning and two high-level feature bullets. There are no code, configuration, binary, or cryptographic changes. Any security relevance of the listed bug fixes is historical and not part of this patch.
