v15 Progress Report, Release Candidate Patch Notes

Version 15 Update

Version 15 of the Nano Node software was released on the beta network early Sunday morning. The developers, alongside the community, have been stringently testing the software in preparation for its release, currently scheduled for the end of this week.

The beta network has been running a steady 4–6 TPS today using minimal bandwidth. Stress tests and spam events are planned this week to test the network under larger loads.

While we are collecting data on the network and will be sharing it as it becomes available, we welcome the community to join us and share their findings. Users can easily access the beta network at https://beta.nano.org/ and get involved.

Our team is very excited about the release of version 15! If you have any questions regarding the upcoming changes, please reach out to Austin or myself on the Nano subreddit.
