PR Review: docs/release-v2.2.0

• Gather context and read changed files
• Review changes
• Post final feedback

---

This is a clean, documentation-only release prep PR. The changes are straightforward and correct.

CHANGELOG.md

• *(Unreleased)* → *(2026-03-29)* — date matches today's release date, correct.
• New ### Build section documents the AGP 9.0.1/Gradle 9.2.1 upgrade and BCV plugin removal with a link to the upstream issue. This is a good addition — library consumers may encounter toolchain differences and the link to BCV #312 provides useful context.

README.md

All 6 version references updated from 2.1.1 → 2.2.0, covering:

• Quick Start snippet
• Version Catalog libs.versions.toml example
• Kotlin DSL snippet
• Network tracking dependency block
• Timber extension dependency block
• Advanced releaseWithOverlay build type example

No references were missed — the diff is complete.

Summary

No issues found. The changes are accurate, consistent, and appropriately scoped for a release documentation update.
