Release P2Pool v1.3.1

This is a bugfix release:

• Fixed startup logic when p2pool is started before monerod or monerod is not yet fully synchronized. It should be safe to start p2pool before monerod now.
• Fixed a crash in p2pool.exe built with msys2
• Multiple smaller fixes and performance improvements
• Slightly reduced memory usage

Wallets with confirmed P2Pool support:

• Official Monero CLI and GUI v0.17.2.3 and newer
• Monerujo v2.1.0 "Vertant" and newer
• Cake Wallet v4.2.7 and newer
• MyMonero

Other wallets might not see P2Pool payouts if they're not updated. Before you start mining, create a new wallet and don't use it for anything else but mining for privacy reasons - all wallet addresses are public on P2Pool! Only primary wallet address is supported - no subaddresses or integrated addresses.

Usage:

• Run monerod binary from the archive: ./monerod --zmq-pub tcp://127.0.0.1:18083 --disable-dns-checkpoints --enable-dns-blocklist
• Run p2pool: ./p2pool --host 127.0.0.1 --wallet YOUR_WALLET_ADDRESS
• Start mining to port 3333 on your machine: ./xmrig -o 127.0.0.1:3333
• You can set custom difficulty for your miner to get more accurate stats on P2Pool side: ./xmrig -o 127.0.0.1:3333 -u x+50000 (it doesn't affect mining rewards in any way)

GPG key to verify SHA256 sums can be downloaded from github or p2pool.io
