We released a new version of branch `mainnet-staging` (git commit hash is `fc8990b1adf06f8311e3c99d5f243062d2f04846` ). To update your node, do the usual: stop your node, run `git checkout mainnet-staging && git pull && make build-deps && eval $(opam env) && make` . If you start your node, you will be prompted by a message telling you to update your storage version. If you were already on `mainnet-staging` , just run `./tezos-node upgrade storage` (possibly with `--data-dir <DIR>` ). If you are on `mainnet` , you have several options:

- start from a clean data directory and import a snapshot, possibly use the new `reconstruct` command (see below);
- bootstrap from scratch.

This new version contains improvements to the new storage backend which make it more reliable and more efficient.

This new version also contains a new command: `reconstruct` , which can be used to convert a `full` node into an `archive` node. This operation is long (a couple of days) but faster than bootstrapping from scratch. It is in particular useful to convert a `mainnet` archive node to the new storage backend: import a snapshot and run `./tezos-node reconstruct`.

We are hoping to release this branch as the new `mainnet` next week. Current `mainnet` will stay as a new legacy branch for a while in case you don’t want to update to the new storage backend.

Is this change going to take less disk space? If so, how much less?
