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.
