Poem

A window once flickered, now calm as can be,
With a tweak to the theme and a frame set free.
No more async delays, just a seamless display,
The search bar now shines in a flickerless way.

Tip

⚡️ Faster reviews with caching

• CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.

Enjoy the performance boost—your workflow just got faster.
