Such transactions have been +non-standard since Bitcoin v0.8.0 (released in February 2013), but were +technically still permitted inside blocks. + +This change breaks the dependency on OpenSSL's signature parsing, and is +required if implementations would want to remove all of OpenSSL from the +consensus code. + +The same miner-voting mechanism as in BIP 34 is used: when 751 out of a +sequence of 1001 blocks have version number 3 or higher, the new consensus +rule becomes active for those blocks. When 951 out of a sequence of 1001 +blocks have version number 3 or higher, it becomes mandatory for all blocks. 0.10.0 Change log ================= |
