## 3.10.5
`2024-8-19`

  + When inside an annotation, an annotation tag will be added at the beginning of the line (VSCode).
  + When between `function () end` or similar constructs, the format will be adjusted to a more reasonable one (VSCode) and leading/trailing spaces will be removed (generic).
