Telebugs Changelog | Product Updates and Releases

See the release announcement.

New Features

• Added project-level muting for one hour, four hours, eight hours, one day, three days, or indefinitely. Existing and new errors are muted while reports continue to be recorded.
• Added safer handling for unusually large error events and release uploads. Reports now show a clear warning when some details were shortened during ingestion.

Improvements

• Improved report Markdown with source links, exact timestamps, notes, and ingestion warnings.
• Added clearer save feedback to notification, webhook, auto-refresh, and accessibility settings.
• Made favorite commands and keyboard shortcut hints more consistent.
• Refreshed the PWA and iOS home-screen icons.

Bug Fixes

• Fixed favorite and settings controls that could show stale state or fail to save reliably.

Improvements

• App cards now use their header space to show the number of projects in the App as a compact stacked badge, with a clearer pointer affordance across the clickable card.

Bug fixes

• Fixed App project choosers remaining expanded, visually misplaced, or unresponsive after opening a project and returning with browser history.
• Fixed error detail pages crashing when grouping metadata was stored as a String or another non-object value, including grouping details for merged errors.
• Prevented the error detail layout from shifting when an error is resolved or unresolved.

Security

• Updated Ruby on Rails to 8.1.3.1 to patch CVE-2026-66066, a critical Active Storage vulnerability that could allow unauthenticated arbitrary file reads and, through exposed secrets, remote code execution in affected configurations.

Improvements

• Redesigned Apps on the All Projects screen. Opening a stacked App card now presents its projects in a focused, responsive chooser with a reversible source-card animation, keyboard support, and a reduced-motion alternative.
• Improved filtering and project navigation for Apps while keeping App and project management actions close at hand. Project cards and their activity data are activated only when the chooser opens.

Maintenance

• Updated Solid Queue to 1.5.1.

See the release announcement.

New Features

• Added previous-period comparisons to activity trends, with aligned custom ranges, clear period labels, per-error deltas, and release markers.
• Added keyboard navigation and a contextual command palette for error and report triage, including optional character shortcuts, customizable bindings, favorites, and recent commands.
• Added accessible data tables and CSV exports for activity trends, including comparison values and release annotations.

Improvements

• Refined the interface with redesigned All Projects cards, clearer main navigation and settings, and more compact, responsive dashboards.
• Made project selection searchable and redesigned overview filters with responsive date presets, custom UTC ranges, and a staged mobile sheet.
• Added compact, default, and large text sizes, and improved focus, navigation state, and settings organization across the application.

Maintenance

• Updated MCP support to version 1.0.0 while preserving the existing ingestion and API wire formats.

Improvements

• Redesigned the main navigation so Projects, Errors, and Reports are always within reach, with account-wide totals shown on desktop and mobile.
• Added a dedicated Appearance page under Account Settings with visual previews for theme, dashboard width, and font choices.
• Improved project and error report dashboards with more compact controls and expandable activity charts that remember their state.
• Hardened MCP connections by rejecting requests sent to an unconfigured host.

Bug Fixes

• Fixed activity counts, links, and sparklines so they follow the selected date range and remain readable across long time periods.

Maintenance

• Updated Ruby to 4.0.6 and refreshed runtime dependencies.

See the release announcement.

New Features

• Added Ingest Protection under Instance settings. Admins can configure a global accepted-errors-per-minute limit, queue protection, and a low-disk-space guardrail directly in the UI.
• Telebugs now returns 429 Too Many Requests before writing ingest payloads or enqueueing jobs when rate, queue, or disk pressure limits are reached.
• Added global warning banners for active ingest protection states, with links to focused documentation for rate limiting, queue protection, and disk space protection.
• Added Maintenance Activity, an admin-visible history for destructive cleanup work and database VACUUM runs. Activity records include status, source, actor, project scope, timestamps, safe result details, cursor pagination, and linkable detail pages.
• Added bin/load, a repeatable k6-based load testing harness for benchmarking Telebugs ingest and processing capacity on real hardware.

Improvements

• Moved Service Messages into the Instance administration area and kept redirects from the old Service Messages URLs.
• Reorganized Instance administration around Ingest Protection, Maintenance Activity, Service Messages, Error Retention, and Artifact Retention.

Improvements

• Added recognizable MCP client logos for Claude, Cursor, Windsurf, and Codex where available, including on the connected MCP apps page.

See the release announcement.

New Features

• Added MCP support. Telebugs now exposes a Streamable HTTP MCP endpoint at /mcp, OAuth/PKCE authorization, dynamic client registration, discovery metadata, and read/write scoped access for AI tools.
• Added MCP tools for listing projects, project users, error groups, reports, and notes; inspecting groups and reports; resolving, unresolving, muting, unmuting, assigning, unassigning, and merging error groups; and adding or deleting notes.
• Added a new Connected MCP apps settings page where users can see MCP applications that have access to their account and revoke access.
• Added bulk muting, unmuting, and merging of error groups in project error lists, the All Errors view, the REST API, and MCP tools.

Improvements

• Reverted the “All Errors” and “All Reports” views to the table layout, as it conserves more space and some users preferred it. The new look remains for mobile viewports. This provides the best of both worlds.
• Added support for log messages from logging integrations such as Serilog for .NET.

Maintenance

• Updated the sqlite3 library to version 2.8.0.

Blog post

New Features

• Introduced error muting, allowing users to snooze errors temporarily (for 1 hour, 4 hours, 8 hours, 1 day, or 3 days) or mute them indefinitely.
• Added a new error status bar that displays key details such as ownership, mute status (including who muted it and when), and resolution (including who resolved it and when) in a compact format alongside the error image. Hovering reveals a detailed popover.
• Implemented bottom sheets on mobile for muting errors and other popovers, featuring intuitive icons (bell with clock for snoozing, slashed bell for permanent muting) to enhance touch-friendly interactions.

Improvements

• Fixed UI overflow of timestamps in the error reports view.

Maintenance

• Updated the sqlite3 library to version 2.7.0.

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 saving email credentials with an empty username and password incorrectly set the fields to empty strings instead of nil.
• Fixed an issue where email notifications would get stuck in the queue after being enqueued.

• 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.
