Wait until it has completely +shut down (which might take a few minutes in some cases), then run the +installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on macOS) +or `bitcoind`/`bitcoin-qt` (on Linux). + +Upgrading directly from a version of Bitcoin Core that has reached its EOL is +possible, but it might take some time if the data directory needs to be migrated. Old +wallet versions of Bitcoin Core are generally supported. + +Compatibility +============== + +Bitcoin Core is supported and tested on operating systems using the +Linux Kernel 3.17+, macOS 13+, and Windows 10+. Bitcoin +Core should also work on most other Unix-like systems but is not as +frequently tested on them. It is not recommended to use Bitcoin Core on +unsupported systems. + +Notable changes +=============== + +This release fixes an issue where the chainstate database would repeatedly +rewrite large portions of itself, causing excessive disk reads and writes +during normal operation. + +### Validation + +- #35209 validation: correct lifetime of precomputed tx data +- #35465 coins: compact chainstate regularly + +### Leveldb + +- #61(bitcoin-core/leveldb): Disable seek compaction + +### Wallet + +- #34358 wallet: fix removeprunedfunds bug with conflicting transactions +- #34870 wallet: feebumper, fix crash when combined bump fee is unavailable +- #34888 wallet: fix amount computed as boolean in coin selection +- #35228 wallet: use outpoint when estimating input size + +### Net + +- #34093 netif: fix compilation warning in QueryDefaultGatewayImpl() +- #34549 net: reduce log level for PCP/NAT-PMP NOT_AUTHORIZED failures + +### PSBT + +- #34272 psbt: Fix PSBTInputSignedAndVerified bounds assert +- #34219 psbt: validate pubkeys in MuSig2 pubnonce/partial sig deserialization + +### Miniscript + +- #34434 miniscript: correct and_v() properties + +### Build + +- #34228 depends: Unset SOURCE_DATE_EPOCH in gen_id script +- #34281 build: Temporarily remove confusing and brittle -fdebug-prefix-map +- #34554 build: avoid exporting secp256k1 symbols +- #34627 guix: use a temporary file over sponge, drop moreutils +- #34713 depends: Allow building Qt packages after interruption +- #34754 depends: Qt fixes for GCC 16 compatibility +- #34787 build: fix native macOS deployment +- #34848 cmake: Migrate away from deprecated SQLite3 target +- #34956 depends, qt: Fix build on aarch64 macOS 26.4 + +### Test + +- #34185 test: fix feature_pruning when built without wallet +- #34282 qa: Fix Windows logging bug +- #34390 test: allow overriding tar in get_previous_releases.py +- #34409 test: use ModuleNotFoundError in interface_ipc.py +- #34445 fuzz: Use AFL_SHM_ID for naming test directories +- #34608 test: Fix broken --valgrind handling after bitcoin wrapper +- #34690 test: Add missing timeout_factor to zmq socket +- #34869 tests: applied PYTHON_GIL to the env for every test +- #34918 fuzz: [refactor] Remove unused g_setup pointers +- #35080 test: Add missing self.options.timeout_factor scale in tool_bitcoin_chainstate.py + +### Util + +- #34597 util: Fix UB in SetStdinEcho when ENOTTY + +### Doc + +- #34252 doc: add 433 (Pay to Anchor) to bips.md +- #34413 doc: Remove outdated -fdebug-prefix-map section in dev notes +- #34510 doc: fix broken bpftrace installation link +- #34561 wallet: rpc: manpage: fix example missing `fee_rate` argument +- #34671 doc: Update Guix install for Debian/Ubuntu +- #34702 doc: Fix fee field in getblock RPC result +- #34706 doc: Improve dependencies.md IPC documentation +- #34789 doc: update build guides pre v31 +- #35283 doc: mention -DWITH_ZMQ=ON in BSD build guides + +### CI + +- #32513 ci: remove 3rd party js from windows dll gha job +- #34344 ci: update GitHub Actions versions +- #34453 ci: Always print low ccache hit rate notice +- #34461 ci: Print verbose build error message in test-each-commit +- #34802 ci: Bump GHA actions versions +- #34815 ci: bump cirruslabs actions versions +- #35202 ci: restore sockets in i686, no IPC job +- #35378 ci: switch runners from cirrus to warpbuild +- #35408 ci: 35378 followups + +### Misc + +- #35175 multi_index: fix compilation failure with boost >= 1.91 + +Credits +======= + +Thanks to everyone who directly contributed to this release: + +- ANAVHEOBA +- andrewtoth +- brunoerg +- Cory Fields +- Daniel Pfeifer +- darosior +- fanquake +- furszy +- Hennadii Stepanov +- jayvaliya +- junbyjun1238 +- kevkevinpal +- Lőrinc +- m3dwards +- marcofleon +- MarcoFalke +- mzumsande +- nervana21 +- Padraic Slattery +- ryanofsky +- Sebastian Falbesoner +- SomberNight +- tboy1337 +- theuni +- ToRyVand +- willcl-ark + +As well as to everyone that helped with translations on +[Transifex](https://explore.transifex.com/bitcoin/bitcoin/).
