Version 4.19 both Free and Pro have been released. Of interest may be the Free Portable edition. All downloads are available from this link
As has been happening with previous updates, my Pro giveaway edition has updated to the new version through the updater in the Settings page. I assume it will just cut off doing so when the year license has expired. Then it may revert to the Free version. Even so, the free version has quite a few utilities.
I did notice a giveaway for the Pro edition but I could not ascertain the version number of the giveaway. Clicking the download button got no reaction. That may indicate the giveaway is over or the page has a fault. I am not sure which. In any case, the Wise Care 365 Pro appears on the giveaway sites frequently so keep a look out for it.
