-## [0.2.0] - 2025-12-04
+## [0.7.0] - 2026-08-28
+
+### Changed
+
+- Upgraded dependencies: clap 4.6.6, imap 3.0.0-alpha.15, native-tls 0.2.18
+- Migrated IMAP client to the imap 3.x `ClientBuilder` and `AppendCmd` APIs
+- Docker images are now tagged with the crate version on main and the short commit SHA otherwise
+- Upgraded build toolchain to Rust 1.98 (pinned via `rust-toolchain.toml`)
+- Updated Docker images: builder `rust:1.98-trixie`, runtime Debian trixie with `libssl3t64`
+
+### Removed
+
+- Unused `imap-proto` dependency
+- Unsound `lexical-core 0.7.6` dependency chain (RUSTSEC-2023-0086), `cargo audit` is now clean
+
+## [0.6.0] - 2025-12-12
+
+### Changed
+
+- Replaced the third-party `rust-pop3-client` crate with a custom POP3 implementation
+- POP3 messages are now retrieved as raw bytes over native-tls, without encoding or line ending conversions
+- Reduced dependency footprint by dropping `rust-pop3-client`
+
+### Fixed
+
+- POP3 byte-stuffing (doubled leading dots) is now handled correctly
+- Original email byte structure is preserved during retrieval
+
+## [0.5.0] - 2025-12-10
+
+### Fixed
+
+- `X-WS-*` headers (e.g. `X-WS-Attachment-UUID`) are now detected as MIME headers so adjacent attachment headers (`Content-Type`, `Content-Disposition`) get normalized properly
+
+### Added
+
+- Test case for attachment header normalization
+
+## [0.3.0] - 2025-12-04
