-## [v1.90.0]
+## [v1.89.0]
 - Expanded built-in revocation support with new YAML revocation flows for Cloudflare, Confluent, Doppler, Mapbox, Particle.io, Twitch, and additional Vercel token formats.
 - Added revocation coverage documentation: new `docs/REVOCATION_PROVIDERS.md` matrix and README links highlighting supported revocation providers/rule IDs.
-
-## [v1.89.0]
 - Access Map: added Microsoft Teams provider. Parses Incoming Webhook URLs (legacy and workflow-based) to extract tenant and webhook identity, probes for active status, and reports channel-level blast radius. Supports standalone `access-map microsoftteams` (alias `msteams`) and automatic mapping for validated `kingfisher.msteams.*` and `kingfisher.microsoftteamswebhook.*` findings.
 - Added Microsoft Teams scan target: `kingfisher scan teams "QUERY"` searches Teams messages via Microsoft Graph Search API and scans them for secrets, mirroring the Slack integration.
 - Requires `KF_TEAMS_TOKEN` environment variable (Microsoft Graph access token with `ChannelMessage.Read.All` or `Chat.Read` permissions).
