In the case of a search service disruption the status updates will be shown here.
05 Jun 26: There was an attempt to release v7.8.1 with change in search service protocol, but I noticed something is maybe wrong with the server management version (derivative of UE) and reverted all back out of abundance of caution, it was available for at most 20 minutes. If you downloaded it during the short time period (after trying to use the search service since I didn't set the update notification) downgrade to v7.8 since there is no clear UE notification when the search protocol has been possibly downgraded (which will be now added, since I didn't foresee such scenario, it will be something positive to come out of this). It might be very few users in single digits who are affected. The message will be removed after I sort it out and make the release now maybe as v7.8.2. It is also possible that it is nothing, in such a case v7.8.1 will be reinstated.
Later: It appears there was google chrome cashing problem/bug and an older server compilation with the same file name was rather taken from cache than downloaded. I'll restart the server with the newer protocol and if all is ok I'll update the website to the same compilation which was there for a short time. Maybe I didn't wake up when encountered this, the release was compiled 2 days ago btw.
