```
// unbuffered
out, err := httpClient.Subscribe(ctx, "event.type=NewTx and account.name=Jack", 0)

// buffered
out, err := httpClient.Subscribe(ctx, "event.type=NewTx AND account.name=Jack", 20)
```

Before: when the `out` channel is buffered and becomes full, we drop an event (+ log the error)
After: when the `out` channel is buffered and becomes full, we block

**Before it was not apparent to the app when an event was dropped (looking at the logs is manual task). After this PR, if the user does not read from `out` on 1 subscription, all other subscriptions will be stuck too.**

Closes #6161

I'm also going to add the retros for all previous security incidents to this directory - I'd like to have them somewhere more central than the Cosmos Forum, where they currently live.

Add docs on how to get tendermint version into RPC version outputs

```

Missed setting the buffer size on the subscription. Note, this doesn't really "fix" this test (a la ref: https://github.com/tendermint/tendermint/pull/5710).

However, I spent a good chunk of time looking at this test with many logs and I'm pretty sure this is mainly due to the fact that none of the nodes get the conflicting vote in time.

closes: #6127

Fixes the race condition between a callback being set and called during ReCheckTx. Note, I do not see equivalent logic in the gRPC client (anymore) as #5439 suggests, so only the socket client was updated.

closes: #5439
