22 Microsoft ended support for Windows XP on [April 8th, 2014](https://www.microsoft.com/en-us/WindowsForBusiness/end-of-xp-support),
23 an OS initially released in 2001. This means that not even critical security
24 updates will be released anymore. Without security updates, using a bitcoin
25 wallet on a XP machine is irresponsible at least.
27 In addition to that, with 0.12.x there have been varied reports of Bitcoin Core
28 randomly crashing on Windows XP. It is [not clear](https://github.com/bitcoin/bitcoin/issues/7681#issuecomment-217439891)
29 what the source of these crashes is, but it is likely that upstream
30 libraries such as Qt are no longer being tested on XP.
32 We do not have time nor resources to provide support for an OS that is
33 end-of-life. From 0.13.0 on, Windows XP is no longer supported. Users are
34 suggested to upgrade to a newer version of Windows, or install an alternative OS
37 No attempt is made to prevent installing or running the software on Windows XP,
38 you can still do so at your own risk, but do not expect it to work: do not
39 report issues about Windows XP to the issue tracker.
45 ----------------------
47 - `importprunedfunds` only accepts two required arguments. Some versions accept
48 an optional third arg, which was always ignored. Make sure to never pass more
51 Removal of Priority Estimation
52 ------------------------------
54 - Estimation of "priority" needed for a transaction to be included within a target
55 number of blocks has been removed. The rpc calls are deprecated and will either
56 return -1 or 1e24 appropriately. The format for `fee_estimates.dat` has also
57 changed to no longer save these priority estimates. It will automatically be
58 converted to the new format which is not readable by prior versions of the
61 - The concept of "priority" transactions is planned to be removed in the next
62 major version. To prepare for this, the default for the rate limit of priority
63 transactions (`-limitfreerelay`) has been set to `0` kB/minute.
68 Detailed release notes follow. This overview includes changes that affect
69 behavior, not code moves, refactors and string updates. For convenience in locating
70 the code changes and accompanying discussion, both the pull request and
71 git merge commit are mentioned.
75 UTXO set query (`GET /rest/getutxos/<checkmempool>/<txid>-<n>/<txid>-<n>/.../<txid>-<n>.<bin|hex|json>`) responses
76 were changed to return status code HTTP_BAD_REQUEST (400) instead of HTTP_INTERNAL_SERVER_ERROR (500) when requests
77 contain invalid parameters.
79 The first boolean argument to `getaddednodeinfo` has been removed. This is an incompatible change.
81 Call "getmininginfo" loses the "testnet" field in favor of the more generic "chain" (which has been present for years).
