Version 9.0 of the Vim text
editor has been released. The biggest change would appear to be the
addition of the “Vim9 Script” language for editor customization:

The main goal of Vim9 script is to drastically improve
performance. This is accomplished by compiling commands into
instructions that can be efficiently executed. An increase in
execution speed of 10 to 100 times can be expected.

A secondary goal is to avoid Vim-specific constructs and get closer
to commonly used programming languages, such as JavaScript,
TypeScript and Java.
