GNU LilyPond Learning Manual: 2.5.2 Version number

### 2.5.2 Version number

The `\version` statement records the version of LilyPond that was used to write the file:

>     \version "2.12.3"

By convention, this is placed at the top of your LilyPond file.

These annotations make future upgrades of LilyPond go more smoothly. Changes in the syntax are handled with a special program, `convert-ly`, and it uses `\version` to determine what rules to apply. For details, see Updating files with convert-ly.

Other languages: français, español, deutsch.
