The Filecoin Mainnet will be performing a Network Upgrade to v21, codenamed Watermelon, at epoch 3469380 around 2023-12-12T13:30:00Z! This upgrade delivers juicy features and enhancements for SP's operations and FVM, and protocol bug fixes!
Given this upgrade introduces many state changes for the network, state migration may take slightly longer than former upgrades. Therefore, node operators may expect slower block validation times, increased CPU and memory usage, and longer delays for API queries during pre-migration/migration base on the implementation that node operator is using, the size of the states stored in block store, and the hardware spec that's running. Please see implementation release notes for more details.
That being said, core devs are NOT expecting any network disruptions. Nevertheless, we'd like to proactively schedule a longer than usual maintenance window, and kindly ask the Filecoin community to join us monitoring the network post-upgrade and let the implementers know if you have any questions!

Another critical bug was discovered during the testing, and core devs have decided to descope FIP-0070 from nv21 upgrade. Calibration testnet requires to perform another patch upgrade so to deploy the newly scoped v12 actor bundle to the network for community to perform further testing, before it's deployed to mainnet production.
The patch upgrade is scheduled at epoch 1108174, which falls on 2023-11-21T13:00:00Z.
