This release enhances system performance and responsiveness. It also makes connector image downloads more reliable to reduce timeouts and failed playbooks.

## Performance Improvement

Improved system performance by optimizing how authentication tokens are managed during backend processing. Previously, the system could make more authentication requests than necessary while handling certain events. This fix ensures that authentication tokens are reused efficiently and refreshed only when required.

### Enhanced Connector loading

Enhanced connector loading to improve overall job performance, helping playbooks run faster and more reliably.
