Electroneum have just announced that they have released an updated version of their core Electroneum code. This is important for anyone running a pool, exchange or using the command-line tools. You must upgrade to the current version before ETN block 179840.
This version fixes a bug that the community have been worried about as well as implementing hundreds of new lines of code with fixes and features. ETN App and web wallet users don't need to do anything, as this is only for technical operators of Electroneum.
