···55- **Draft backups** — every compose session is automatically backed up to `~/.cache/neomd/drafts/` before the temp file is deleted; keeps a rolling 20 backups (configurable via `draft_backup_count` in `[ui]`, set to `-1` to disable); no more lost emails after crashes or accidental closes
66- **`:recover` / `:rec` command** — reopens the most recent draft backup as a compose session; To/Cc/Bcc/Subject are parsed from the backup and pre-filled automatically
77- **Screener docs: "screening happens once"** — documented that auto-screening only runs on the Inbox folder; emails moved to ToScreen by another device are not re-classified; use `:reset-toscreen` to move them back for re-screening
88-- **Test suite** — 147 tests across 8 packages covering screener classification, MIME message building, editor parsing, config loading, IMAP search, OAuth2 token handling, rendering, and security invariants (file permissions, BCC privacy, credential leak prevention); CI workflow runs `go test` + `go vet` on every PR
88+- **Test suite** — 147 unit tests across 8 packages covering screener classification, MIME message building, editor parsing, config loading, IMAP search, OAuth2 token handling, rendering, and security invariants (file permissions, BCC privacy, credential leak prevention); CI workflow runs `go test` + `go vet` on every PR
99+- **Integration tests** (`make test-integration`) — end-to-end tests against a real IMAP/SMTP server: send plain email and verify From/To/Subject/HTML body round-trip, CC header, file attachment content, non-ASCII subject encoding (umlauts + emoji), IMAP search with `from:`/`subject:` prefixes, and move + undo; all test emails cleaned up automatically; skipped without credentials so `make test` stays fast and offline

1112- **OAuth2 authentication** ([#3](https://github.com/ssp-data/neomd/pull/3), thanks [@notthatjesus](https://github.com/notthatjesus)) — accounts can set `auth_type = "oauth2"` with `oauth2_client_id`, `oauth2_client_secret`, `oauth2_issuer_url`, and `oauth2_scopes` instead of a password; on first launch neomd opens the browser for the authorization code flow, persists the token to `~/.config/neomd/tokens/<account>.json`, and refreshes it automatically; works with Gmail, Office365, and any OIDC-discoverable provider via XOAUTH2 over IMAP and SMTP; password auth paths unchanged for existing accounts
