Important update (source code only)If you are operating a pool or other important service, or if you are solo mining, and you compile your own node, please pull master from github and upgrade ASAP. Likewise if you have AWS images, please rebuild them with the new version. Additional precautionary checkpoints have been added to protect more of the existing blockchain.
Our recommendation and request is for exchanges is to remain frozen for external Monero transactions (trading is fine). If you are still running a node, please update it.

The update is an important precaution.
Updated binaries will follow shortly.
Further measures will be taken as necessary.
