How to Upgrade
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
If you are running an older version, shut it down. 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 Mac)
|
|
|
|
|
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 extensively tested on operating systems
|
|
|
|
|
using the Linux kernel, macOS 10.14+, and Windows 7 and newer. 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.

|
P2P and network changes
|
|
|
|
|
-----------------------
|
|
|
|
|
|
|
|
|
|
- A bitcoind node will no longer rumour addresses to inbound peers by default.
|
|
|
|
|
They will become eligible for address gossip after sending an ADDR, ADDRV2,
|
|
|
|
|
or GETADDR message. (#21528)

|
|
* On startup, the list of banned hosts and networks (via `setban` RPC) in
|
|
|
|
|
`banlist.dat` is ignored and only `banlist.json` is considered. Bitcoin Core
|
|
|
|
|
version 22.x is the only version that can read `banlist.dat` and also write
|
|
|
|
|
it to `banlist.json`. If `banlist.json` already exists, version 22.x will not
|
|
|
|
|
try to translate the `banlist.dat` into json. After an upgrade, `listbanned`
|
|
|
|
|
can be used to double check the parsed entries. (#22570)

|
-------------------
|
|
|
|
|
|
|
|
|
|
- Update `-getinfo` to return data in a user-friendly format that also reduces vertical space. (#21832)

RPC

|
|
|
|
|
|
|
|
|
|
- `getblockchaininfo` now returns a new `time` field, that provides the chain tip time. (#22407)

|
Tests
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
- For the `regtest` network the activation heights of several softforks were
|
|
|
|
|
changed.
|
|
|
|
|
* BIP 34 (blockheight in coinbase) from 500 to 2 (#16333)
|
|
|
|
|
* BIP 66 (DERSIG) from 1251 to 102 (#22632)
