## The second param of listsinceblock

From [issue 8752](https://github.com/bitcoin/bitcoin/issues/8752#issuecomment-247988691)

> The second parameter (target confirmation) is quite strange and should probably be better > documented in the RPC help of listsinceblock (check original comment: #199 (comment))

From the actual docs here is it is:

> target-confirmations:    (numeric, optional) The confirmations required, must be 1 or more

However, that's misleading at best. I've seen at least one project thinking that `target-confirmations` means "filter to only show transactions of n target-confirmations". It's a weird param but I'd document it as

> target-confirmations: (numeric, optional) Return the hash of the block that has target-confirmations of confirmations, for use in a further call to listsinceblock
## Transactions confirmations

Says:

> "confirmations": n,       (numeric) The number of confirmations for the transaction. Available for 'send' and 'receive' category of transactions.

It should also say when it's < 0, it means the transaction conflicted that many blocks ago
## bip125-replaceable

There's an undocumented field of transactions "bip125-replaceable" which I believe has three possibilities "yes" "no" and "unknown"  (under what circumstances it says unknown, should also be documented)

"\nArguments:\n"
            "1. \"txid\"    (string, required) The transaction id\n"
