Compatibility
|
|
|
|
|
==============
|
|
|
|
|
|
|
|
|
|
Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
|
|
|
|
|
an OS initially released in 2001. This means that not even critical security
|
|
|
|
|
updates will be released anymore. Without security updates, using a bitcoin
|
|
|
|
|
wallet on a XP machine is irresponsible at least.
|
|
|
|
|
|
|
|
|
|
In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
|
|
|
|
|
randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891)
|
|
|
|
|
what the source of these crashes is, but it is likely that upstream
|
|
|
|
|
libraries such as Qt are no longer being tested on XP.
|
|
|
|
|
|
|
|
|
|
We do not have time nor resources to provide support for an OS that is
|
|
|
|
|
end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
|
|
|
|
|
suggested to upgrade to a newer version of Windows, or install an alternative OS
|
|
|
|
|
that is supported.
|
|
|
|
|
|
|
|
|
|
No attempt is made to prevent installing or running the software on Windows XP,
|
|
|
|
|
you can still do so at your own risk, but do not expect it to work: do not
|
|
|
|
|
report issues about Windows XP to the issue tracker.

Notable changes
|
|
|
|
|
===============
|
|
|
|
|
|
|
|
|
|
Low-level RPC changes
|
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
|
|
- `importprunedfunds` only accepts two required arguments. Some versions accept
|
|
|
|
|
an optional third arg, which was always ignored. Make sure to never pass more
|
|
|
|
|
than two arguments.
|
|
|
|
|
|
|
|
|
|
Removal of Priority Estimation
|
|
|
|
|
------------------------------
|
|
|
|
|
|
|
|
|
|
- Estimation of "priority" needed for a transaction to be included within a target
|
|
|
|
|
number of blocks has been removed. The rpc calls are deprecated and will either
|
|
|
|
|
return -1 or 1e24 appropriately. The format for `fee_estimates.dat` has also
|
|
|
|
|
changed to no longer save these priority estimates. It will automatically be
|
|
|
|
|
converted to the new format which is not readable by prior versions of the
|
|
|
|
|
software.
|
|
|
|
|
|
|
|
|
|
- The concept of "priority" transactions is planned to be removed in the next
|
|
|
|
|
major version. To prepare for this, the default for the rate limit of priority
|
|
|
|
|
transactions (`-limitfreerelay`) has been set to `0` kB/minute.

0.14.0 Change log
|
|
|
|
|
=================
|
|
|
|
|
|
|
|
|
|
Detailed release notes follow. This overview includes changes that affect
|
|
|
|
|
behavior, not code moves, refactors and string updates. For convenience in locating
|
|
|
|
|
the code changes and accompanying discussion, both the pull request and
|
|
|
|
|
git merge commit are mentioned.

|
|
|
|
|
|
|
|
|
### RPC and REST
|
|
|
|
|
|
|
|
|
|
UTXO set query (`GET /rest/getutxos/<checkmempool>/<txid>-<n>/<txid>-<n>/.../<txid>-<n>.<bin|hex|json>`) responses
|
|
|
|
|
were changed to return status code HTTP_BAD_REQUEST (400) instead of HTTP_INTERNAL_SERVER_ERROR (500) when requests
|
|
|
|
|
contain invalid parameters.
|
|
|
|
|
|
|
|
|
|
The first boolean argument to `getaddednodeinfo` has been removed. This is an incompatible change.
|
|
|
|
|
|
|
|
|
|
Call "getmininginfo" loses the "testnet" field in favor of the more generic "chain" (which has been present for years).
