Deprecation Notice
The Gemini 2.5 Flash family of models is deprecating in October. Start testing newer models now to ensure a smooth migration. For more details on Gemini model deprecations, see Google's Gemini deprecations page . For the full list of supported models and pricing tiers, see the Voice Agent LLM Models documentation .
Fedora 42 has reached end of life
Fedora 42 has reached end of life. Per our image deprecation policy, this image is available exclusively via the API for the next 30 days before we remove it from our platform.
AI-Detected Issues Now Generally Available
Sentry can use AI to analyze your traces and logs to detect issues that traditional pattern-matching would miss, like database inefficiencies, blocking operations, and security concerns.
Next Generation Events now available in developer preview
Next Generation Events are now available in developer preview. Events give you field-level control over when a subscription fires, what data it carries, and what triggers each delivery, fixing three common friction points faced with traditional webhooks: over-delivery, fixed payloads, and no built-in signal for what changed.
Frustration Analytics , Debugger on User Profile Timeline
What: The User Profile Timeline now surfaces frustration signals directly alongside behavioral events – error events with distinct styling, key properties inline, error-focused filtering, and quick links to Session Replay. This gives you a chronological view of exactly what a specific user experienced.
GitHub CLI 2.93.0
Security A security vulnerability has been identified, and fixed, that would incorrectly include authorization header in API requests to TUF repository mirrors via gh attestation , gh release verify , and gh release verify-asset commands. Users are advised to update gh to version v2.93.0 as soon as possible.
