Hash: SHA256
The new key-binding system mentioned in the previous entry is finally
here! After years of work, done primarily by Dennis van der Schagt, we
now have a `bind` command that:
* can create multi-key bindings, i.e. one can bind not just single
letters (with Control or Shift), but also sequences of letters (each
with their own modifiers);
* allows each binding to execute multiple actions, just like our
existing `macro` command. Unlike macros, `bind` doesn't require
a "macro prefix", so one can finally bind a sequence of operations to
a _single_ key;
* allows adding documentation strings to each binding, which are then
shown in the help dialog. This again is an improvement upon macros,
which had no descriptions and didn't have a way for the user to
provide their own;
* adds alternative syntax for keys. Instead of the usual ^R syntax, one
can now use <C-r> a la Tmux or Emacs. Hopefully this makes multi-key
bindings easier to read.
The feature is very new, and probably contains bugs. Please report them!
In fact, it's so new that we didn't have time to finish the
corresponding `unbind` command LOL. However, since Newsboat doesn't have
any multi-key bindings by default, `unbind` was deemed to not be
a release blocker.
The new feature also has a limitation in that multi-key bindings that
have the same prefix must have the same length. In other words, it's
fine to have `abc` and `abx` bound simultaneously, but it's not possible
to bind both `ab` and `abc` at the same time. This is to avoid an
ambiguity when the prefix is typed; in that case Newsboat would have to
decide somehow if the next key is going to be c.
We are all very proud of this feature, and eagerly awaiting your
feedback! Please try it, and open an issue if something doesn't work or
could be improved.
One more thing: we now require a compiler that accepts
`-std=c++17` flag. In other words, we dropped Clang 4 support. This is
due to libicu 75 requiring C++17; we depend on this library via libxml2,
and the requirement bleeds through to us because we're indirectly
including some of libicu header files.
Compilers without C++17 support are now considered deprecated. Future
Newsboat releases will probably use some of C++17 features, at which
point we'll drop support. If that's going to create problems for you,
please file an issue.

That one doesn't verify either. Oh well. At least the .asc on the
Hash: SHA256
release tarball is correct.
