There will be a full update and a date set around 2 weeks from the wallet release for the hard-fork to let everyone update wallets.
We were planning to implement a hard fork at block 100,000 to activate a fix for the PoS overflow issue and also fork in the masternode network and other features. We are running behind schedule with the wallet and will push the hard fork forward to block 110,000 (roughly 13 days from now (which is block 92,924 at the time of writing this)). This will take us to Sunday 15/05/2016 at around 1630 hours (GMT). We will make every effort to release the new wallet at least 7 days ahead of the hard fork, so around 08/05/2016. We will announce this here, on Twitter, on the Blog, on the website and Facebook and contact the exchanges directly. We also need to update the seed nodes and Tor nodes and the block explorer. There should be plenty of time for everyone to get the upgrade done.
