Backblaze Release 4.0.2

By | May 12th, 2015

Release Date: 5/12/2015
Version 4.0.2

Backblaze version 4.0.2 is out today! The latest Backblaze version is also becoming the minimum version of Backblaze that you can use. As part of this a dialog has been added to the installer to protect against older installers being launched (they will now direct you to download the latest Backblaze version, 4.0.2 or higher).

Additionally we have optimized large file retransmission, especially in cases where a user would have a slower internet connection. This should occur less often.

Finally in the Mac OS X 10.10.4 beta release, the Locate My Computer feature was causing an issue that would use a lot of RAM, this was caused by Apple changing one of the paths that we used to calculate location, resulting in a loop. This has since been fixed and users running Mac OS X 10.10.4 and Backblaze 4.0.2 should no longer be experiencing RAM usage spikes.

Auto-updates will begin rolling out over the next few days. If you’d like the latest version now, please see below for instructions.
