 * [\#9835](https://github.com/cosmos/cosmos-sdk/pull/9835) Moved capability initialization logic to BeginBlocker to fix nondeterminsim issue mentioned in [\#9800](https://github.com/cosmos/cosmos-sdk/issues/9800). Applications must now include the capability module in their BeginBlocker order before any module that uses capabilities gets run.
 * [\#9201](https://github.com/cosmos/cosmos-sdk/pull/9201) Fixed `<app> init --recover` flag.

 ### API Breaking Changes
 
 * [\#9835](https://github.com/cosmos/cosmos-sdk/pull/9835) The `InitializeAndSeal` API has not changed, however it no longer initializes the in-memory state. `InitMemStore` has been introduced to serve this function, which will be called either in `InitChain` or `BeginBlock` (whichever is first after app start). Nodes may run this version on a network running 0.42.x, however, they must update their app.go files to include the capability module in their begin blockers.
