### Bug Fixes

+ [\#9965](https://github.com/cosmos/cosmos-sdk/pull/9965) Fixed `simd version` command output to report the right release tag.

### API Breaking Changes
* (client/tx) [\#9421](https://github.com/cosmos/cosmos-sdk/pull/9421/) `BuildUnsignedTx`, `BuildSimTx`, `PrintUnsignedStdTx` functions are moved to
the Tx Factory as methods.
* [\#9965](https://github.com/cosmos/cosmos-sdk/pull/9965) Fixed `simd version` command output to report the right release tag.

### Client Breaking Changes

* [\#10041](https://github.com/cosmos/cosmos-sdk/pull/10041) Remove broadcast & encode legacy REST endpoints. Please see the [REST Endpoints Migration guide](https://docs.cosmos.network/master/migrations/rest.html) to migrate to the new REST endpoints.

## [v0.43.0](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.43.0) - 2021-08-10

* (x/capability) [\#9836](https://github.com/cosmos/cosmos-sdk/pull/9836) Removed `InitializeAndSeal(ctx sdk.Context)` and replaced with `Seal()`. App must add x/capability module to the begin blockers which will assure that the x/capability keeper is properly initialized. The x/capability begin blocker must be run before any other module which uses x/capability.
