Support Electrum protocol v1.6 #172
Description
The Electrum protocol v1.6 was just merged. See the docs for changes in the new version:
Changes
Breaking change for the version negotiation: we now mandate that the server.version() message must be the first message sent. That is, version negotiation must happen before any other messages.
Also for server.version(), the server must tolerate and ignore extraneous arguments, to allow for extensions in future protocol versions.
The status of a scripthash has its definition tightened in a backwards-compatible way: mempool txs now have a canonical ordering defined for the calculation (previously their order was undefined).
blockchain.scripthash.get_mempool() previously did not define an order for mempool transactions. We now mandate a specific ordering.
Optional mode argument added to blockchain.estimatefee().
blockchain.block.headers() now returns headers as a list, instead of a single concatenated hex string.
New methods
blockchain.transaction.broadcast_package() to broadcast a package of transactions (submitpackage).
mempool.get_info() to get more detailed and general relayfee info.
Removed methods
- blockchain.relayfee() is removed. The minrelaytxfee field of the new mempool.get_info() RPC is a direct replacement.
It would be great if electrs could support the new features very soon. For us (LDK), support for the new blockchain.transaction.broadcast_package is particularly important, as we want to lean on TRUC/v3 transaction relay via Electrum ASAP.
