Release notes: This release contains a huge amount of new features, bug fixes, and performance improvements. It is worth noting that v2.0 Postgres delta backups are not backward-compatible with the pre-2.0 versions. It means that the v2.0 delta backup can't be restored with the v1.1 or earlier versions. Also, this release introduces the initial support for Greenplum physical backups.
WAL-G for MySQL now supports the parallel backup-push/backup-fetch and has an optimized binlog upload mechanism. WAL-G for SQLServer now supports the backup encryption and compression as well as the external storage backup import/export. WAL-G v2.0 is available for download on [our GitHub releases page](https://github.com/wal-g/wal-g/releases/tag/v2.0.0 "our GitHub releases page").
