We received many requests regarding Ndless for OS 4.3.
However, updating Ndless to support a newer OS release is a lot of time-consuming work, this time it took a bit longer than expected. Long enough that OS 4.4 was getting close enough to just skip 4.3 entirely.
This version was originally meant to be released in a few days, but early tests turned out to be so successful (suspiciously successful) that we decided to just flip the switch earlier.
And here you go: Ndless for OS 184.108.40.2062 is ready for download!
