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 for older versions), then run the |
||||||
|
installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac) |
||||||
|
or `bitcoind`/`bitcoin-qt` (on Linux). |
||||||
|
|
||||||
|
The first time you run version 0.15.0 or higher, your chainstate database will |
||||||
|
be converted to a new format, which will take anywhere from a few minutes to |
||||||
|
half an hour, depending on the speed of your machine. |
||||||
|
|
||||||
|
The file format of `fee_estimates.dat` changed in version 0.15.0. Hence, a |
||||||
|
downgrade from version 0.15 or upgrade to version 0.15 will cause all fee |
||||||
|
estimates to be discarded. |
||||||
|
|
||||||
|
Note that the block database format also changed in version 0.8.0 and there is no |
||||||
|
automatic upgrade code from before version 0.8 to version 0.15.0. Upgrading |
||||||
|
directly from 0.7.x and earlier without redownloading the blockchain is not supported. |
||||||
|
However, as usual, old wallet versions are still supported. |
||||||
|
|
||||||
|
Downgrading warning |
||||||
|
------------------- |
||||||
|
|
||||||
|
The chainstate database for this release is not compatible with previous |
||||||
|
releases, so if you run 0.15 and then decide to switch back to any |
||||||
|
older version, you will need to run the old release with the `-reindex-chainstate` |
||||||
|
option to rebuild the chainstate data structures in the old format. |
||||||
|
|
||||||
|
If your node has pruning enabled, this will entail re-downloading and |
||||||
|
processing the entire blockchain. |
||||||
|
|
||||||
|
Compatibility |
||||||
|
============== |
||||||
|
|
||||||
|
Bitcoin Core is extensively tested on multiple operating systems using |
||||||
|
the Linux kernel, macOS 10.8+, and Windows Vista and later. Windows XP is not supported. |
||||||
|
|
||||||
|
Bitcoin Core should also work on most other Unix-like systems but is not |
||||||
|
frequently tested on them. |
||||||
|
|
||||||
|
|
||||||
|
Notable changes |
||||||
|
=============== |
||||||
|
|
||||||
|
Network fork safety enhancements |
||||||
|
-------------------------------- |
||||||
|
|
||||||
|
A number of changes to the way Bitcoin Core deals with peer connections and invalid blocks |
||||||
|
have been made, as a safety precaution against blockchain forks and misbehaving peers. |
||||||
|
|
||||||
|
- Unrequested blocks with less work than the minimum-chain-work are now no longer processed even |
||||||
|
if they have more work than the tip (a potential issue during IBD where the tip may have low-work). |
||||||
|
This prevents peers wasting the resources of a node. |
||||||
|
|
||||||
|
- Peers which provide a chain with less work than the minimum-chain-work during IBD will now be disconnected. |
||||||
|
|
||||||
|
- For a given outbound peer, we now check whether their best known block has at least as much work as our tip. If it |
||||||
|
doesn't, and if we still haven't heard about a block with sufficient work after a 20 minute timeout, then we send |
||||||
|
a single getheaders message, and wait 2 more minutes. If after two minutes their best known block has insufficient |
||||||
|
work, we disconnect that peer. We protect 4 of our outbound peers from being disconnected by this logic to prevent |
||||||
|
excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable |
||||||
|
number of nodes not known to be on bogus chains. |
||||||
|
|
||||||
|
- Outbound (non-manual) peers that serve us block headers that are already known to be invalid (other than compact |
||||||
|
block announcements, because BIP 152 explicitly permits nodes to relay compact blocks before fully validating them) |
||||||
|
will now be disconnected. |
||||||
|
|
||||||
|
- If the chain tip has not been advanced for over 30 minutes, we now assume the tip may be stale and will try to connect |
||||||
|
to an additional outbound peer. A periodic check ensures that if this extra peer connection is in use, we will disconnect |
||||||
|
the peer that least recently announced a new block. |
||||||
|
|
||||||
|
- The set of all known invalid-themselves blocks (i.e. blocks which we attempted to connect but which were found to be |
||||||
|
invalid) are now tracked and used to check if new headers build on an invalid chain. This ensures that everything that |
||||||
|
descends from an invalid block is marked as such. |
||||||
|
|
||||||
|
|
||||||
|
Miner block size limiting deprecated |
||||||
|
------------------------------------ |
||||||
|
|
||||||
|
Though blockmaxweight has been preferred for limiting the size of blocks returned by |
||||||
|
getblocktemplate since 0.13.0, blockmaxsize remained as an option for those who wished |
||||||
|
to limit their block size directly. Using this option resulted in a few UI issues as |
||||||
|
well as non-optimal fee selection and ever-so-slightly worse performance, and has thus |
||||||
|
now been deprecated. Further, the blockmaxsize option is now used only to calculate an |
||||||
|
implied blockmaxweight, instead of limiting block size directly. Any miners who wish |
||||||
|
to limit their blocks by size, instead of by weight, will have to do so manually by |
||||||
|
removing transactions from their block template directly. |
||||||
|
|
||||||
|
|
||||||
|
GUI settings backed up on reset |
||||||
|
------------------------------- |
||||||
|
|
||||||
|
The GUI settings will now be written to `guisettings.ini.bak` in the data directory before wiping them when |
||||||
|
the `-resetguisettings` argument is used. This can be used to retroactively troubleshoot issues due to the |
||||||
|
GUI settings. |
||||||
|
|
||||||
|
|
||||||
|
Duplicate wallets disallowed |
||||||
|
---------------------------- |
||||||
|
|
||||||
|
Previously, it was possible to open the same wallet twice by manually copying the wallet file, causing |
||||||
|
issues when both were opened simultaneously. It is no longer possible to open copies of the same wallet. |
||||||
|
|
||||||
|
|
||||||
|
Debug `-minimumchainwork` argument added |
||||||
|
---------------------------------------- |
||||||
|
|
||||||
|
A hidden debug argument `-minimumchainwork` has been added to allow a custom minimum work value to be used |
||||||
|
when validating a chain. |
||||||
|
|
||||||
|
|
||||||
|
Low-level RPC changes |
||||||
|
---------------------- |
||||||
|
|
||||||
|
- The "currentblocksize" value in getmininginfo has been removed. |
||||||
|
|
||||||
|
- `dumpwallet` no longer allows overwriting files. This is a security measure |
||||||
|
as well as prevents dangerous user mistakes. |
||||||
|
|
||||||
|
- `backupwallet` will now fail when attempting to backup to source file, rather than |
||||||
|
destroying the wallet. |
||||||
|
|
||||||
|
- `listsinceblock` will now throw an error if an unknown `blockhash` argument |
||||||
|
value is passed, instead of returning a list of all wallet transactions since |
||||||
|
the genesis block. The behaviour is unchanged when an empty string is provided. |
||||||
|

||||||
