There is a new version of the Dolphin Viewer 3 out. It is version 3.0.5.20427. There are few fixes. One notable is the change to a separate cache. Most third party viewers (TPV) now use their own cache.
The RLV enable switch in preferences has been renamed.
Whispering is now mentioned in the chat Tool Tip…
The Linux builds have been fixed to work with older Linux versions.
Summary
If you have made a separate cache for your Dolphin Viewer, this is not an important download. If not, you can save the download by making a change in Preferences.
There may be some other bug fixes not mentioned on the Dolphin site. So, you may want this version.
