|
(CLTV) consensus change, and relay policy preparation for BIP113. It is

Upgrading and downgrading
|
|
|
|
|
=========================

|
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/Kevacoin-Qt (on Mac) or
|
|
|
|
|
kevacoind/kevacoin-qt (on Linux).

|
Downgrade warning
|
|
|
|
|
------------------
|
|
|
|
|
|
|
|
|
|
Because release 0.10+ and later makes use of headers-first synchronization and
|
|
|
|
|
parallel block download (see further), the block files and databases are not
|
|
|
|
|
backwards-compatible with pre-0.10 versions of Kevacoin Core or other software:
|
|
|
|
|
|
|
|
|
|
* Blocks will be stored on disk out of order (in the order they are
|
|
|
|
|
received, really), which makes it incompatible with some tools or
|
|
|
|
|
other programs. Reindexing using earlier versions will also not work
|
|
|
|
|
anymore as a result of this.
|
|
|
|
|
|
|
|
|
|
* The block index database will now hold headers for which no block is
|
|
|
|
|
stored on disk, which earlier versions won't support.
|
|
|
|
|
|
|
|
|
|
If you want to be able to downgrade smoothly, make a backup of your entire data
|
|
|
|
|
directory. Without this your node will need start syncing (or importing from
|
|
|
|
|
bootstrap.dat) anew afterwards. It is possible that the data from a completely
|
|
|
|
|
synchronised 0.10 node may be usable in older versions as-is, but this is not
|
|
|
|
|
supported and may break as soon as the older version attempts to reindex.
|
|
|
|
|
|
|
|
|
|
This does not affect wallet forward or backward compatibility.

Notable changes since 0.10.3
|
|
|
|
|
============================
|
|
|
|
|
|
|
|
|
|
BIP65 soft fork to enforce OP_CHECKLOCKTIMEVERIFY opcode
|
|
|
|
|
--------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
This release includes several changes related to the [BIP65][] soft fork
|
|
|
|
|
which redefines the existing OP_NOP2 opcode as OP_CHECKLOCKTIMEVERIFY
|
|
|
|
|
(CLTV) so that a transaction output can be made unspendable until a
|
|
|
|
|
specified point in the future.
|
|
|
|
|
|
|
|
|
|
1. This release will only relay and mine transactions spending a CLTV
|
|
|
|
|
output if they comply with the BIP65 rules as provided in code.
|
|
|
|
|
|
|
|
|
|
2. This release will produce version 4 blocks by default. Please see the
|
|
|
|
|
*notice to miners* below.
|
|
|
|
|
|
|
|
|
|
3. Once 951 out of a sequence of 1,001 blocks on the local node's best block
|
|
|
|
|
chain contain version 4 (or higher) blocks, this release will no
|
|
|
|
|
longer accept new version 3 blocks and it will only accept version 4
|
|
|
|
|
blocks if they comply with the BIP65 rules for CLTV.
|
|
|
|
|
|
|
|
|
|
**Notice to miners:** Kevacoin Core’s block templates are now for
|
|
|
|
|
version 4 blocks only, and any mining software relying on its
|
|
|
|
|
getblocktemplate must be updated in parallel to use libblkmaker either
|
|
|
|
|
version v0.4.3 or any version from v0.5.2 onward.
|
|
|
|
|
|
|
|
|
|
- If you are solo mining, this will affect you the moment you upgrade
|
|
|
|
|
Kevacoin Core, which must be done prior to BIP65 achieving its 951/1001
|
|
|
|
|
status.
|
|
|
|
|
|
|
|
|
|
- If you are mining with the stratum mining protocol: this does not
|
|
|
|
|
affect you.
|
|
|
|
|
|
|
|
|
|
- If you are mining with the getblocktemplate protocol to a pool: this
|
|
|
|
|
will affect you at the pool operator’s discretion, which must be no
|
|
|
|
|
later than BIP65 achieving its 951/1001 status.

Windows bug fix for corrupted UTXO database on unclean shutdowns
|
|
|
|
|
----------------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
Several Windows users reported that they often need to reindex the
|
|
|
|
|
entire blockchain after an unclean shutdown of Kevacoin Core on Windows
|
|
|
|
|
(or an unclean shutdown of Windows itself). Although unclean shutdowns
|
|
|
|
|
remain unsafe, this release no longer relies on memory-mapped files for
|
|
|
|
|
the UTXO database, which significantly reduced the frequency of unclean
|
|
|
|
|
shutdowns leading to required reindexes during testing.
|
|
|
|
|
|
|
|
|
|
For more information, see: <https://github.com/bitcoin/bitcoin/pull/6917>
|
|
|
|
|
|
|
|
|
|
Other fixes for database corruption on Windows are expected in the
|
|
|
|
|
next major release.
