ibc-go v10 release candidate
Pre-release
This is the third release candidate for ibc-go v10.0.0.
Like most unreleased software, it is not recommended to use this in production as it might still have bugs and unexpected behavior.
The changelog and migration docs are not up-to-date yet, but some notable changes from v8 are below:
New versioning scheme for modules
Previously, the modules in the ibc-go repo has been versioned and branched separately from ibc-go. Starting with v10, modules/light-clients/08-wasmwill follow and release together with ibc-go. So the first stable release of both modules will be {MODULE_NAME}/v10.0.0. The callbacks module has been included in ibc-go's own module, and is therefore not a separate module anymore.
You can find releases and notes for those modules separately.
