12 Upgrading and downgrading
13 =========================
18 If you are running an older version, shut it down. Wait until it has completely
19 shut down (which might take a few minutes for older versions), then run the
20 installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
21 bitcoind/bitcoin-qt (on Linux).
26 Because release 0.10.0 and later makes use of headers-first synchronization and
27 parallel block download (see further), the block files and databases are not
28 backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
30 * Blocks will be stored on disk out of order (in the order they are
31 received, really), which makes it incompatible with some tools or
32 other programs. Reindexing using earlier versions will also not work
33 anymore as a result of this.
35 * The block index database will now hold headers for which no block is
36 stored on disk, which earlier versions won't support.
38 If you want to be able to downgrade smoothly, make a backup of your entire data
39 directory. Without this your node will need start syncing (or importing from
40 bootstrap.dat) anew afterwards. It is possible that the data from a completely
41 synchronised 0.10 node may be usable in older versions as-is, but this is not
42 supported and may break as soon as the older version attempts to reindex.
44 This does not affect wallet forward or backward compatibility.
49 This fixes a serious problem on Windows with data directories that have non-ASCII
50 characters (https://github.com/bitcoin/bitcoin/issues/6078).
52 For other platforms there are no notable changes.
