Version 1.5 Released. Version 1.5 is a mandatory upgrade, so please upgrade as soon as possible to avoid a fork. Version 1.5 fixes the superblock issue, making Graincoin the first coin ever to generate superblock in a truely random way. This will eliminate the hackers from getting most of the superblocks. Version 1.5 also includes some minor bug fixes. The switchover point is set at block 310000, which will be in about 5-7 days (we are at block 277100 now). Download links for Windows Client and source in github are updated.
Pool OPS, please pay attention that the block following the bonus block (the one that should have x8 or x64 payout) has two coinbase transactions: the standard one, at index 0 and the nonstandard at index 1 for PoW blocks and at index 2 for PoS blocks. This extra tx has a bonus block reward (x7 or x63) for the previous block that is distributed proportionally between all output addresses listed in the actual bonus block coinbase tx.P.S. I will provide the ubuntu version shortly.
