## Bug Fixes

### Performance Fix: Slow S3 Downloads on Linux (#372)
- **Removed `O_DSYNC` flag** that was forcing synchronous writes and eliminating OS buffering
- Downloads now use standard buffered I/O for significantly improved throughput

### Goroutine Leak in Performance Tests (#378)
- Fixed goroutine leak in `mc support perf` when nodes report errors
- Prevents all nodes from incorrectly showing errors when only one node fails

### Incomplete Uploads Ignored (#346)
- Fixed `mc rm --force --recursive --versions --incomplete` now properly removes incomplete multipart uploads

### Access Key Expiration Display (#344)
- Non-expiring access keys now correctly show `expires: never` instead of `a long while ago`
- Fixed handling of zero-value timestamps in expiration display

### ILM Size Filter Edits (#335)
- `mc ilm rule edit` now properly applies `--size-gt` and `--size-lt` flags
- Previously these flags were silently ignored during rule edits

### Batch List Table Header (#327)
- Added missing `BUCKET` column to `mc batch list` table output

### XML Error Response Parsing (#333)
- Table commands now properly parse and display XML error responses from the server
