Chatto

Chatto 0.2.0

Release notes

This release covers the full 0.2.0 line since 0.1.0: Markdown previews while composing, notification badge counts, direct-message room sidebars, email-code throttling, and a clearer Docker runtime layout.

0.2.0

Markdown previews in the composer

The composer can preview Markdown while you write, including formatting shortcuts, links, code fences, syntax highlighting, and language selection for code blocks.

Notification badge counts

Room rows and the server gutter show notification counts, while unread-message dots remain separate. Badge counts can be loaded without waiting for a websocket event.

Room sidebar controls in direct messages

Direct-message rooms now expose the room sidebar where it makes sense, including the files panel, while keeping DM moderation actions hidden.

Running and Integrating Chatto

Section titled “Running and Integrating Chatto”

Email-code throttling is configurable

Registration and email-verification codes have configurable guardrails for expiration, resend throttling, wrong-code attempts, and disabling throttling for controlled environments. Failed sends roll back their OTP records, so delivery problems do not consume throttle capacity.

Upgrade Notes

Section titled “Upgrade Notes”
  • Docker self-hosters should move mounts from the old /home/chatto layout to /config/chatto.toml and /data.
  • Review registration and email-verification OTP throttling settings if your deployment relies on custom signup or verification flows.
  • SMTP providers that require SMTPS on port 465 can use implicit TLS instead of trying to force STARTTLS semantics.

Smaller fixes you’ll appreciate

Auth, email, and server runtime

Section titled “Auth, email, and server runtime”
  • CSRF tokens are stateless and bound to the authenticated cookie-session generation.
  • Server lifecycle logs are less noisy and include clearer shutdown and metrics startup details.

Rooms, notifications, and calls

Section titled “Rooms, notifications, and calls”
  • Navigating from a notification into a different server remounts the room route so server-scoped room state is rebuilt correctly.
  • Room and directory state refresh after room creation and room layout changes.
  • Direct-message rows show active call badges consistently.

Docker and operations

Section titled “Docker and operations”
  • Docker containers use the documented config and data root paths.
  • Implicit SMTP TLS works for SMTPS providers.
