Hi Michael,
The new version 1.5.9 includes changes in description of extension, because it was incomplete. All other changes you can check on GitHub: hFramework. New version of extension is only an update of hFramework library.
About your problem with CTRL+SHIFT+B, we will continue this subject in previous topic. Post one more time and include as much information as you can (versions of VSC, extension, errors). We will investigate it.
Regards,
Hubert
