## 0.7.6 - 2026-09-11

### Miscellaneous Tasks

- Always use --locked flag in CI

### Performance

- Don't keep multiple copies of the same mail data in memory

## 0.7.5 - 2026-09-10

### Performance

- Pass HttpsClient by reference instead of cloning it
- Remove connection pool

### Refactor

- Do not evaluate smtp_write! argument twice
- Do not clone the Config unnecessarily
