# KDL Changelog

## 2.0.0 (2022-08-28)
|
|
|
|
### Grammar
|
|
|
|
* Solidus/Forward slash (`/`) is no longer an escaped character.
|
|
* Single line comments (`//`) can now be immediately followed by a newline.
|
|
* All literal whitespace following a `\` in a string is now discarded.
|
|
* Vertical tabs (`U+000B`) are now considered to be whitespace.
|
|
* Identifiers can't start with `r#`, so they're easy to distinguish from raw
|
|
strings. (They already similarly can't start with a digit, or a sign+digit,
|
|
so they're easy to distinguish from numbers.)
|
|
* The grammar syntax itself has been described, and some confusing definitions
|
|
in the grammar have been fixed accordingly (mostly related to escaped
|
|
characters).
|
|
* `,`, `<`, and `>` are not legal identifier characters. They were previously
|
|
reserved for KQL but this is no longer necessary.
|
|
|
|
### KQL
|
|
|
|
* There's now a _required_ descendant selector (`>>`), instead of using plain
|
|
spaces for that purpose.
|
|
* The "any sibling" selector is now `++` instead of `~`, for consistency with
|
|
the new descendant selector.
|
|
* Map operators have been removed entirely.
