The team has been working hard on a collection of fixes and user-requested features, while also continuing to support the Midnight Glacier Drop. Perhaps most interestingly we have added the ability to bring in partial amount when performing a commit. We continue to work on important improvements and user requests, we will start to investigate the partial fanout feature we've wanted to work on for a while, and continue to support the Glacier Drop!

Big thanks to Juan and Jonathan for big contributions to these recent releases!

High-level summary​

The team have been highly focused on work supporting the glacier drop; in particular fixing a bug related to replaying a large statefile, and preparing a release that includes that fix (0.22.2). We continue work to improve some observed issues with our resiliance to restarts during processing high volumes of transactions.

What did the team achieve?​

• Released version 0.22.2

• Resolved bug with node getting into deadlock while restarting #2089
• Show a list off "Offline" peers in the TUI #2044
• Set the content-type for the API server responses #2094
• Small fix to the documentation #2095
• Continued to support the glacier drop

What's next?​

• Focus on improving crash-resiliance #2109
