+# Increased V2 Allow Height to 52400
+
+Delays activation of the v2 hardfork to June 6th, 2025 in response to concerns from some of our partners on the scope of updates necessary to support v2. Also shortens the period between phase 1 and phase 2 of the hardfork to around 14 days. This shortened period should not adversely affect implementors since they can start sending V2 transactions and using V2 contracts immediately after phase 1 activates.
