Upgrade notices¶

All nodes are encouraged to upgrade to V27.1, including exchanges.

In general, exchanges, services and integrations are encouraged to join the test network for performing integration testing. This network mimics the live network in work requirements but has a smaller number of nodes and a lower block count for easier setup.

Database upgrade¶

If you are upgrading from previous versions (e.g. V26), V27 includes a one-way database upgrade that takes a few minutes to run.

If you are upgrading from V27.0, there is no additional database upgrade.

gcc-12 users¶

If your system uses gcc-12 there is a known bug in the compiler optimiser that has problems compiling c++20 code.

If you get a compiler error related to -Wrestrict, it's recomended to either downgrade to gcc-11 or upgrade to gcc-13 to compile the node. See more detail here. Debian 12 (bookworm) ships with gcc-12 by default, but has a package for gcc-11.

Major updates¶

See the V27.0 release notes for the major updates list.
