#### [Features in 2.9dev](Readme.md#devel)
* Support of supplying timeout value for ``openssl connect``
#### Features implemented in [2.9dev](Readme.md#devel)
* Support of supplying timeout value for ``openssl connect`` -- useful for batch/mass scanning
* TLS 1.2 protocol check via socket
* Further TLS socket improvements (Handshake)
* Further TLS socket improvements (Handshake parsing, robustness)
* non-flat JSON support
* in file output (CSV, JSON flat, JSON non-flat) support of a minimum severity level (only above supplied level there will be output)
