Unfortunately, the release of the Russian version of the Heroes 5 v1.4 patch is delayed, just as it was with the Heroes 5 v1.3 version, but this time for an even longer period. Quote from Old boy, who announced the delay of the Russian patch on the official forum of Nival Interactive:

Old boy: Unfortunately, the release of the Russian patch is delayed due to technical reasons, and it will most likely not be released before Monday. We are currently doing everything possible to release it as soon as possible. We will announce the exact date and time of its release as soon as we are sure of them. (...The release of the Chinese patch is also delayed)
