## 1.24.0 (21 April 2024)

- Issue #59: How to register a custom mapper with a complex file extension
  ATTENTION: complex extensions should be escaped in the config file with `/` character due to the VSCode limitations of not handling dots in the config names correctly.
  IE the mapper configuration for `document.git.md` file should be encoded in the setting.jeson as ` "codemap.git/md": "config:codemap.md",`
