-This release introduces bug fixes and improvements. Notably, the upgrade to Tendermint [v0.34.24](https://github.com/tendermint/tendermint/releases/tag/v0.34.24).
+This release introduces bug fixes and improvements. Notably, the SDK have now switched to Informal Systems' Tendermint fork.
+Their fork has no changes compared to the upstream Tendermint, but it is now [maintained by Informal Systems](https://twitter.com/informalinc/status/1613580954383040512). Chains are invited to do the same.
 
-Please read the release notes of [v0.46.5](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.46.5) if you are upgrading from `<=0.46.4`.
+Moreover, this release contains a store fix. The changes have been tested against a v0.46.x chain mainnet with no issues. However, there is a low probability of an edge case happening. Hence, it is recommended to do a **coordinated upgrade** to avoid any issues.
 
-A critical vulnerability has been fixed in the group module. For safety, `v0.46.5` and `v0.46.6` are retracted, even though chains not using the group module are not affected. When using the group module, please upgrade immediately to `v0.46.7`.
+Please see the [CHANGELOG](https://github.com/cosmos/cosmos-sdk/blob/release/v0.46.x/CHANGELOG.md) for an exhaustive list of changes.
 
-An issue has been discovered in the gov module's votes migration. It does not impact proposals and votes tallying, but the gRPC queries on votes are incorrect. This issue is fixed in `v0.46.7`, however:
-- if your chain is already on v0.46 using `<= v0.46.6`, a **coordinated upgrade** to v0.46.7 is required. You can use the helper function `govv046.Migrate_V046_6_To_V046_7` for migrating a chain **already on v0.46 with versions <=v0.46.6** to the latest v0.46.7 correct state.
-- if your chain is on a previous version <= v0.45, then simply use v0.46.7 when upgrading to v0.46.
