We have just released an update to our code editors addressing following issues:
* Improved: SFTP connectivity with modern SFTP servers without backwards compatibility. The very latest standards are now used.
* Fixed: SFTP issue with Keep Alive on some SFTP servers.
We are also working on the next generation of our code editors, however to implement some of the requests, we had to dramatically change our development environment and invest heavily in some new components and it takes time. At the present moment we do not know when the next major release will be available. Our tentative target is 2018 Q1-Q2.
