The first release candidate for 409k is out, and target release date for 409k is next Tuesday ~2025.12.9.
The network has constantly been under heavy load since soon after software distribution released. This is because when ship A pokes ship B the poke will keep retrying forever until ship B installs the agent being poked. This is true even if ship A has long since suspended or even nuked the agent!
409 ameliorates the issue by creating a system flow between ships A and B, effectively causing B to notify A when (if ever) he installs the agent. Until that time no more packets will be sent. It is worth noting that this is an important step for enabling directed messaging on the network as a default.
The release includes support for the quickboot brass pill that speeds up initial boot from minutes to seconds. We also enable the spin hint for ship performance monitoring, visit <your-ship>/~_~/spin to see it in action.
For a list of breaking changes, pre-release pill and instructions on how to install the release candidate, see https://github.com/urbit/urbit/releases/tag/409k-rc1
