Over time the "transaction +priority" stuff has added a huge amount of code and taken a bunch of +otherwise-useful developer effort. There is still some debate about its +usefulness going forward, but there was general agreement that it will +either be removed entirely or replaced with something a bit less costly +to maintain some time around 0.13. + +With the mempool limiting stuff already in git master, high-priority +relay is disabled when mempools are full. In addition, there was +agreement to take the following steps for 0.12: + + * Mining code will use starting priority for ease of implementation + * Default block priority size will be 0 + * Wallet will no longer create 0-fee transactions when mempool limiting +is in effect. + +What this means for you is, essentially, be more careful when relying on +priority to mine your transactions. If mempools are full, your +transactions will be increasingly less likely to be relayed and more +miners may start disabling high-priority block space. Make sure you +analyze previous blocks to determine if high-priority mining is still +enabled and ensure your transactions will be relayed. + +Matt + |
