v27.0

mautrix-teams 27.0 aligns versioning with the underlying mautrix-go release
line; future patch releases will track it as 27.0.x. The release fixes the
meeting/group/channel naming gap, breaks a tight Trouter reconnect loop, and
stops the bridge re-inviting you to portals you have manually left.

Fixed

• Group, channel and meeting portals now pick up their Teams topic. The
  per-thread /v1/threads/<id> API returns thread metadata under the
  top-level properties key, while /conversations (used at startup)
  uses threadProperties; we now read either, and fall back to the
  calendar subject parsed from properties.meeting JSON for meeting
  threads where neither topic is set.
• Trouter /v4/a registration now refreshes the skype token on a 401 and
  retries once. Without this the bridge would enter a 5-second reconnect
  loop after Microsoft rotated the websocket and the cached skype token
  expired in the gap, hammering the auth endpoint until manual restart.
• Startup chat sync no longer re-invites you to portals you have manually
  left in Matrix. The bridge checks the room's member state and skips the
  resync when your membership is leave or ban. Live messages still
  trigger re-invite, as before.
• Unknown Teams contacts (no profile available, no cached display name)
  show as the bare AAD GUID instead of the full 8:orgid:<guid> MRI, and
  DM rooms with such contacts no longer get the bare MRI written into the
  room name; Element falls back to the ghost's display name instead.

v26.04.2

mautrix-teams 26.04.2 brings live incoming-call notices, fixes the bot
avatar that re-uploaded on every restart, and patches the OAuth bearer
prerequisite so the skype-token refresh recovers cleanly when Azure
revokes a bearer ahead of its stored expiry.

Added

• Incoming Teams calls now post a live 📲 Incoming call from <name>
  notice in the caller's DM portal within ~1s of the ring, with a
  self-mention so Element fires a Matrix push notification.
• Post-call summaries from the 48:calllogs system thread are parsed and
  re-routed to the real conversation portal (DM partner for 1:1, thread
  for group calls) instead of opening a virtual 48:calllogs portal that
  the Teams API rejects with HTTP 400.
• Call notices include direction, caller display name (with cache fallback
  for outgoing calls where Teams omits targetParticipant.displayName),
  and call duration when available. Self-calls and voicemail legs are
  skipped.

Fixed

• Bot avatar is no longer re-uploaded on every restart. The mxc cache
  file now lives in the bridge working directory (writable under the
  systemd unit's ReadWritePaths) so PrivateTmp=yes no longer wipes it
  on boot.
• RefreshSkypeToken now refreshes the OAuth bearer first when the
  cached one has expired, and retries once on a 401 from the authz
  endpoint. This was masking expired-bearer cases as msteams: token expired and stalling read receipts and outbound Matrix events between
  full reconnect cycles.

v26.04.1

Fixed

• Backfill on Synapse now respects max_initial_messages instead of stopping
  at one Teams page. The internal pagination loop also counts only
  bridgeable messages toward the target so non-chat events don't shrink it.
• Multi-part messages (text + attachment, etc.) get distinct part IDs so
  they no longer collide on bridgev2's (message_id, part_id) UNIQUE
  constraint, which was aborting forward backfill mid-stream.
• Inline Teams emoticons (:wink: etc.) render as Unicode in the message
  body instead of being split out as standalone m.image parts.
• Messages that convert to nothing (empty HTML shells, system events) are
  skipped via bridgev2.ErrIgnoringRemoteEvent instead of being posted as
  blank m.text placeholders.
• History messages now populate parent_id (thread reply target) and
  reactions from properties.emotions and conversationLink.
• Reactions are deduped by (key, MRI) when parsing emotions so Teams's
  per-emoji history (multiple add/remove cycles) doesn't replay as
  duplicate Matrix reaction events.
• RichText/UriObject (inline images and screenshots) is now treated as
  a chat message type and bridged.
• DM portal invites carry is_direct: true so Element auto-marks them as
  direct chats without requiring double-puppeting.
