### Breaking Changes
### Improvements
- Custom checkpoint support added. (
- Lease Manager improvements to reduce checkpoint store I/O. (
- Enforce stricter request timeouts in Azure Storage Lease Manager. (
- Limit max number of expired lease single host can acquire. This helps to avoud single host acquiring more leases than it can handle. (
### Bug fixes
- PartitionManager to notify exception to error handler during store initialization. (
- Limit receiver identifiers to maximum 64 characters to avoid receiver failures in processor host with long names. (
- Enforce request timeout at ListBlobsSegmentedAsync call to avoid lease manager hung. (
- Don't block PartitionManager loop on close pump call. This avoids expiry of all leases due to blocking renew lease cycle. (
