123.2 Release Notes
2==================
3
4Bitcoin Core version 23.2 is now available from:
5
6  <https://bitcoincore.org/bin/bitcoin-core-23.2/>
7
8This release includes various bug fixes and performance
9improvements, as well as updated translations.
10
11Please report bugs using the issue tracker at GitHub:
12
13  <https://github.com/bitcoin/bitcoin/issues>
14

18
19How to Upgrade
20==============
21
22If you are running an older version, shut it down. Wait until it has completely
23shut down (which might take a few minutes in some cases), then run the
24installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on macOS)
25or `bitcoind`/`bitcoin-qt` (on Linux).
26
27Upgrading directly from a version of Bitcoin Core that has reached its EOL is
28possible, but it might take some time if the data directory needs to be migrated. Old
29wallet versions of Bitcoin Core are generally supported.
30
31Compatibility
32==============
33
34Bitcoin Core is supported and extensively tested on operating systems
35using the Linux kernel, macOS 10.15+, and Windows 7 and newer.  Bitcoin
36Core should also work on most other Unix-like systems but is not as
37frequently tested on them.  It is not recommended to use Bitcoin Core on
38unsupported systems.
39
40### P2P
41
42- #26909 net: prevent peers.dat corruptions by only serializing once
43- #27608 p2p: Avoid prematurely clearing download state for other peers
44- #27610 Improve performance of p2p inv to send queues
45
46### Build system
47
48- #25436 build: suppress array-bounds errors in libxkbcommon
49- #25763 bdb: disable Werror for format-security
50- #26944 depends: fix systemtap download URL
51- #27462 depends: fix compiling bdb with clang-16 on aarch64
52
53### Miscellaneous
54
55- #25444 ci: macOS task imrovements
56- #26388 ci: Use macos-ventura-xcode:14.1 image for "macOS native" task
57- #26924 refactor: Add missing includes to fix gcc-13 compile error
