### Bug Fixes

* (baseapp) [#16259](https://github.com/cosmos/cosmos-sdk/pull/16259) Ensure the `Context` block height is correct after `InitChain` and prior to the second block.
* (x/staking) [#16043](https://github.com/cosmos/cosmos-sdk/pull/16043) Call `AfterUnbondingInitiated` hook for new unbonding entries only and fix `UnbondingDelegation` entries handling
* (types) [#16010](https://github.com/cosmos/cosmos-sdk/pull/16010) Let `module.CoreAppModuleBasicAdaptor` fallback to legacy genesis handling.
* (x/group) [#16017](https://github.com/cosmos/cosmos-sdk/pull/16017) Correctly apply account number in group v2 migration.

defer is usually for resource cleanup, I think it's clearer to simply put the code after the commit call, for example if panic happens before it, there's no point to still run this code.

Although the tutorial on defer states that, there's no idiomatic usage of it.

defer is often used where e.g. ensure and finally would be used in other languages.

Finally is exactly what we're trying to do here. I think if we do it in Commit, we'll have to explicitly check if height == 0.

I mean just after the initChainer call, I think we don't want to run this if there's any errors or panics?

ahh yes, the reason why I added in the defer is if initChainer == nil, you'll need to add it before the return. That's why I added in the defer instead of having it twice.

// InitChain represents the state of the application BEFORE the first block,
// i.e. the genesis block. This means that when processing the app's InitChain
// handler, the block height is zero by default. However, after Commit is called
// the height needs to reflect the true block height.
initHeader.Height = req.InitialHeight
app.checkState.ctx = app.checkState.ctx.WithBlockHeader(initHeader)

can we set this in header info as well?

Header info? What do you mean by that?

app.deliverState.ctx = app.deliverState.ctx.WithBlockHeader(initHeader)
}()

if app.initChainer == nil {
return

w/o this fix, this value is actually 0 which would cause CheckTx to fail for txs prior to the 1st block.
