Release notes

🚧 THIS IS AN EXPERIMENTAL RELEASE.
We don't recommend running it on your main validator infrastructure. It brings major improvements, but we're still unsure about its downsides and long-term effects. The latest stable version is 1.25.4.

IMPORTANT
To fully benefit from this release, you must resync your nodes from scratch.
Half-path is now the default sync mode for new nodes. If you start this version on a node with an old database schema, it will continue using the old schema without improvements. This is not recommended.

Major highlights

• Next HalfPath upgrade - This is a next release which brings an experimental state redesign called "HalfPath". More details can be found in 1.26.0-exp.2 and in our blog post

• SNAP SERVING - This version also introduces experimental (still under testing) mechanism for serving snap data! This is very important milestone done which will improve health of Ethereum (now only Geth is capable of serving Snap data so Nethermind can reduce very high responsibility of Geth and serve this data as well).
  Since we are still working on it users can experience some worse performance when snap data is served - we are working on optimizing it.

• Dencun ready version for Experimental users - All users which are running experimental version are asked to migrate to this version since this is the only experimental version with Dencun support. All previous versions will stop working once hard fork occurs.

Known issues

Full pruning doesn't work properly. You may experience very long pruning times, which at the end may not work as expected causing big block processing spikes - we are working on solution but it is not advised to use it at all at the moment.
