We recommend that you space out your commits to avoid hitting the rate limit.

🚦 How do rate limits work?

CodeRabbit enforces hourly rate limits for each developer per organization.

Our paid plans have higher rate limits than the trial, open-source and free plans. In all cases, we re-allow further reviews after a brief timeout.

📝 Walkthrough

Walkthrough

The pull request prevents redundant changelog generation when a package version remains unchanged. Early-exit logic is added to both the core changelog update function and the workflow task builder, with corresponding test coverage verifying that changelog files are not rewritten when versions match.

Changes

Version Equality Changelog Skip

Layer / File(s)	Summary
Core Logic src/core/changelog.ts	generateChangelogEntry skips compareUrl generation when previousVersion equals version; updateChangelog returns early with verbose log when versions match.
Workflow Integration src/workflows/prepare.ts	Changelog task builder skips commit fetching and updateChangelog call when package currentVersion equals newVersion.
Test Coverage test/core/changelog.test.ts	New test case verifies CHANGELOG.md is not rewritten when version and previousVersion are identical, even with new commits available.

Poem

🐰 A changelog unchanged, stays still as can be,
No writes, no compares, just quiet and free.
When versions don't budge, we skip the whole show—
Less friction, less noise, and whoosh—off we go! 🌱
