DFSee 16

DFSee version 16.9 released

DFSee version 16.9 has been released, which is a MINOR release with some bugfixes. Because this is a MINOR release, you get it for FREE if you already have a 16.x key.

Of course, as usual, there are also smaller improvements and bug fixes.

DFSee is a very powerful disk-utility with disk partitioning, filesystem and disk analysis, file recovery/UNDELETE and smart imaging or cloning of partitions or complete disks.

It will require an upgrade if you currently have a registration for an older MAJOR version.

Adding Let’s Encrypt’s new root and intermediate certificates to Mozilla applications

On September 30, 2021, Let’s Encrypt’s DST Root CA X3 cross-sign expired, leaving many web browsers to report that sites using Let’s Encrypt SSL certificates were “untrusted” or “unknown.”

Let’s Encrypt did, in fact, implement a new root and intermediate certificates some time ago, but after the built-in certificate stores in the Mozilla applications shipped with all versions of ArcaOS 5.0 to date (5.0 through 5.0.6) were configured. Thus, these new certificates were not included in those builds, and as a result, the new root certificate is indeed unknown.

The fix is relatively simple, and a rather common procedure for all browsers and email clients. To bring your Firefox, Thunderbird, and SeaMonkey certificate stores up to date, and learn how to do this for other new certificates as they become available, we’ve added a new wiki page, here.
