All the above packages are a major update, requiring rebuilds of all that depend on them.
Imagemagick was not a known .so up, version went from 6.9.6.7 to 6.9.6.8, so it was already uploaded to the [build] repo.
The ongoing rebuilds for the other 3 are not completed yet, but all builds will be uploaded now, so the needed imagemagick rebuilds will reach you now.
Openjpeg & Imagemagick rebuilds are complete, so you can update your system for that.
The ICU/Boost update is not complete, so do not update for the next 24 hours if you need all apps depending on those 2 right now.
List of rebuilds left, will be done within 24 hours:
