The core developers of Ethereum have called for a delay to the activation of Constantinople hard fork, just hours before it was scheduled to go live on the Ethereum network. 

Major Ethereum clients such as Go-Ethereum (Geth) and Parity have released software updates following the decision, which came after blockchain audit firm Chain Security discovered a security vulnerability in Ethereum Improvement Proposal (EIP) 1283, one of the planned changes included in Constantinople that sought to introduce a cheaper gas cost for SSTORE operations. If exploited, the vulnerability would have permitted "re-entrance attacks" which would allow funds to be withdrawn from the same source multiple times. 

Since the hard fork has been delayed, cryptocurrency exchanges, miners, and other node operators must either upgrade to emergency released software updates or downgrade to the previous pre-fork release (less recommended) or get disconnected from the main Ethereum network.

The new activation block for the upgrade will be decided during another call later this week.
