The release introduces various improvements and bug fixes.

Some hightlights:

  • Fix a bug where the node would fail to produce a block if it cannot find the recent VDF checkpoints in the cache;
  • improve the node behaviour under disk space constraints:
    • stop writing data to storage modules residing on the separate drives when less than 1% of the disk space remains available;
    • stop writing data to storage modules on the data_dir drive when the remaining space is less than what is reserved for the disk pool and block headers cache;
  • fix a bug introduced in 2.6.4 where the node may fail to join the network when only some of the specified trusted peers are not available;
  • add support for syncing exclusively from local peers:
    • to enable the feature, specify local peers to sync from using the local_peer command line parameter and set the sync_from_local_peers_only command line flag;
    • the peer address may be (although it does not have to be) a private IP address;
    • make sure to specify local_peer on both sides - the node does not expect to be rate limited when syncing from a "local" peer so its peer needs to recognize it as local too;
  • the data synchronization is improved;
  • the sync_jobs configuration parameter now determines the number of workers responsible for fetching the chunks from the network and also from the other local storage modules:
    • if you run the node with sync_jobs 0, it won't sync any data from the network and it won't copy and repack the data between storage modules either;
    • if you set a positive value, the node will at first copy and repack the data across the intersecting storage modules and only then attempt to sync the missing data from the network;
    • if you want to copy and repack local storage modules but do not want to sync from the network, start the node with sync_from_local_peers_only (you do not have to specify local_peers).

The release comes with the prebuilt binaries for the Linux x86_64 platforms.
