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, 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.
|
|
|
|
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
|
|
===============
|
|
|
|
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.
|
|
|
|
Low-level RPC changes
|
|
----------------------
|
|
- The "currentblocksize" value in getmininginfo has been removed.
