What is a Release Candidate?

RC stands for Release Candidate. This version has undergone testing and is considered nearly ready for the final stable release. The purpose of an RC is to identify regressions and stabilize the build before the final release.

How to Help Test

• Report bugs on the Issues page
• Check if the bug existed in the previous stable release (e.g., v0.99.0) — this helps us determine priority
• Regressions (bugs introduced since the last stable release) are blockers and receive the regression label
• Bugs that existed in previous versions are lower priority and may be deferred to future releases
