 =============
-- Enforce v2 blocks at height 700000
+- Enforce v2 blocks at height 710000 on mainnet, 400000 on testnet
 - Add `-maxorphantx=<n>` and `-maxorphanblocks=<n>` options for control over the maximum orphan transactions and blocks
 - Stricter memory limits on CNode
 - Upgrade OpenSSL to 1.0.1i (see https://www.openssl.org/news/secadv_20140806.txt - just to be sure, no critical issues
