@item 2.2 --- 15 March 2017
The virtual machine and introduced in 2.0 was completely rewritten,
along with much of the compiler and toolchain. This speeds up many
Guile programs as well as reducing startup time and memory usage. A PEG
parser toolkit was added, making it easier to write other language
frontends.
Guile programs as well as reducing startup time and memory usage.
Guile's POSIX multithreading was improved, stacks became dynamically
expandable, the ports facility gained support for non-blocking I/O.
@item 3.0 -- early 2019 (unreleased at time of writing)
Guile gained support for native code generation via a simple
just-in-time (JIT) compiler, further improving the speed of its virtual
machine.

pure-Guile applications out there, users still need to drop down to C

pure-Guile applications out there, in the past users have still needed
to drop down to C for some tasks: interfacing to system libraries that
don't have prebuilt Guile interfaces, and for some tasks requiring high

compiler in Guile 3.0, most of these older applications can now be
updated to move more C code to Scheme.
Still, even with an all-Guile application, sometimes you want to
