Telebugs CLI

• The Telebugs CLI now automatically prunes old images left behind by the update command. It still keeps the previous version of the app (before the update) for rollback purposes.

• Fixed a bug where sending a webhook with unescaped characters caused Discord and Slack to reject the payload and return an error.
• Added links to relevant documentation pages in the UI.

Bug Fixes

• Fixed a bug in the calculation of negative UTC timezone offsets that caused incorrect "Today" determination in certain time zones at specific times of day. The issue was due to using UTC time instead of local time for display. The "Today" calculation is now accurate across all time zones.
• Fixed broken toggles for notification channels in Project settings. Previously, toggles did not control notification sending, causing notifications to be sent regardless of toggle state. Now, notifications are sent only when toggles are enabled.
• Fixed the Regenerate button in the Project Token settings, which previously did not respond to user interaction.
• Fixed a bug in the error report view where HTTP request data represented as a string caused the page to crash instead of displaying properly.

Improvements

• Improved the alert text for the Regenerate button in Team Management settings to clarify that regenerating the link will invalidate the current one.
• Added admin information to the project list view for newly joined team members. Previously, new members saw no projects or guidance. Now, they see a message instructing them to contact an admin for project access, along with a list of available admins.
• Added automatic page refresh upon the arrival of the first error. Previously, users had to refresh manually to see new errors. Now, the page refreshes automatically to notify users of errors in real-time.

• Fixed a bug in Notification Configuration where configuring a channel, then disabling it and deleting the configuration would cause the bell icon to remain erroneously.
• Added support for configuring "Domain" and "Authentication" for the email notification channel.

• Fixed a bug in email notifications where the "None" option for the Encryption field didn’t work.
• Fixed a bug where rate limiting on session creation wasn’t functioning correctly.
