We are very excited to announce the 0.5 release of Kopia! This is a big milestone on the way to an upcoming 1.0 release and there have not only been a large number of changes across the stack but also growth of the community.

0.5.1 is a hotfix release that fixes support for 256-bit hashes in index blobs. See #346 for more information.

Key changes

• Creation of both a governance structure for Kopia as well as the adoption of a Code of Conduct
• Addition of better encryption schemes (AES256-GCM-HMAC-SHA256 and CHACHA20-POLY1305-HMAC-SHA256) and deprecation of some weak ciphers.
• Object Storage: Support for Azure Blob and AWS Session Tokens
• Improved kopia.io website
• KopiaUI - desktop client that runs kopia in the background allows quick access to UI from system tray
• Robustness testing framework
• Revamped logging of repository layer and made it pluggable
• Refactored hashing, encryption and splitters into separate packages
• Added ability to embed credentials in kopia connection configuration.
• Fixed SFTP storage
• Cleaned up console output to be less noisy
• Build system now supports macOS, Linux and Windows - all CLI binaries and KopiaUI can be built on all the environments.
• Automatic update notification about new Kopia versions available on GitHub
• Improvements to repository maintenance tooling (compaction, garbage collection, verification)
• New policy options to ignore errors when reading files and directories
• Repository now remembers hostname at connection time to prevent spontaneous changes when changing networks
• Lots of improvements to server HTTP API - now supports running over TLS, dynamic ports and using random password
