Notable changes
Example item
bitcoin-cli: arguments privacy
The RPC command line client gained a new argument, -stdin
to read extra arguments from standard input, one per line until EOF/Ctrl-D.
For example:
$ echo -e "mysecretcode\n120" | src/bitcoin-cli -stdin walletpassphrase
It is recommended to use this for sensitive information such as wallet passphrases, as command-line arguments can usually be read from the process table by any user on the system.
RPC low-level changes
gettxoutsetinfoUTXO hash (hash_serialized) has changed. There was a divergence between 32-bit and 64-bit platforms, and the txids were missing in the hashed data. This has been fixed, but this means that the output will be different than from previous versions.
0.13.0 Change log
Detailed release notes follow. This overview includes changes that affect behavior, not code moves, refactors and string updates. For convenience in locating the code changes and accompanying discussion, both the pull request and git merge commit are mentioned.

Block and transaction handling
P2P protocol and network code
The p2p alert system has been removed in #7692 and the 'alert' message is no longer supported.
Fee filtering of invs (BIP 133)
The optional new p2p message "feefilter" is implemented and the protocol version is bumped to 70013. Upon receiving a feefilter message from a peer, a node will not send invs for any transactions which do not meet the filter feerate. BIP 133
