⚠️ Breaking Changes

• Removed deprecated UploadFile, UploadFileContext, and FileUploadParameters. The files.upload API was discontinued by Slack on November 12, 2025. ([#1481])
• Renamed UploadFileV2 → UploadFile, UploadFileV2Context → UploadFileContext, and UploadFileV2Parameters → UploadFileParameters. The "V2" suffix is no longer needed now that the old API is removed. ([#1481])

Added

• Audit Logs example - New example demonstrating how to use the Audit Logs API. ([#1144])
• Admin Conversations API support - Comprehensive support for admin.conversations.*
  methods including core operations (archive, unarchive, create, delete, rename, invite,
  search, lookup, getTeams, convertToPrivate, convertToPublic, disconnectShared, setTeams),
  bulk operations (bulkArchive, bulkDelete, bulkMove), preferences, retention management,
  restrict access controls, and EKM channel info. ([#1329])

Changed

• BREAKING: Removed deprecated UploadFile, UploadFileContext, and
  FileUploadParameters. The files.upload API was discontinued by Slack on November

• BREAKING: Renamed UploadFileV2 → UploadFile, UploadFileV2Context →
  UploadFileContext, and UploadFileV2Parameters → UploadFileParameters. The "V2"
  suffix is no longer needed now that the old API is removed. ([#1481])

Fixed

• File upload error wrapping - UploadFile now wraps errors with the step name
  (GetUploadURLExternal, UploadToURL, or CompleteUploadExternal) so callers can
  identify which of the three upload steps failed. ([#1491])
• Audit Logs API endpoint - Fixed GetAuditLogs to use the correct endpoint
  (api.slack.com) instead of the regular API endpoint (slack.com/api). The Audit
  Logs API requires a different base URL. Added OptionAuditAPIURL for testing. ([#1144])
• Socket mode websocket dial debugging - Added debug logging when a custom dialer is
  used including HTTP response status on dial failures. This helps diagnose proxy/TLS
  issues like "bad handshake" errors. ([#1360])
• MsgOptionPostMessageParameters now passes MetaData - Previously, metadata was
  silently dropped when using PostMessageParameters. ([#1343])
