How to prepare Erigon release (things not to forget)

Update DB Schema version if required

In the file db/kv/tables.go there is variable DBSchemaVersion that needs to be updated if there are any changes in the database schema, leading to data migrations. In most cases, it is enough to bump minor version.

Update remote KV version if required

In the file db/kv/remotedbserver/remotedbserver.go there is variable KvServiceAPIVersion that needs to be updated if there are any changes in the remote KV interface, or database schema, leading to data migrations. In most cases, it is enough to bump minor version. It is best to change both DB schema version and remote KV version together.

Update app.go

After a release branch has been created, update db/version/app.go. Let's say you're releasing Erigon v3.6.0. Then in branch release/3.6 of erigon set Major = 3, Minor = 6, Micro = 0, Modifier = "", and DefaultSnapshotGitBranch = "release/3.6". (Don't forget to create branch release/3.6 of erigon-snapshot.) In branch main of erigon set Major = 3, Minor = 7, Micro = 0, and Modifier = "dev".
