With numerous quality improvements (including over 130 tests thanks to Mats) and many new features; the documentation is still being worked on but both the INSTALL file and the Hyperbole manual explain how to install it from git source now using the Straight package manager.
In this version, Hyperbole has become a global minor mode for easy toggling of its key bindings.
Get it from the hyperbole git repo at savannah at
gnu.org or from github.com:/rswgnu/hyperbole. There is a tarball release there as well.
More will come out across the week as time allows.
Enjoy.
Bob and Mats
