Valid in: Schematic and Symbol files

    type version fileformat_version

Pos. | Field | Type/unit | Description
--- | --- | --- | ---
# | type | char | v
1 | version | int | version of gEDA/gaf that wrote this file
2 | fileformat_version | int | gEDA/gaf file format version number

- The type is a lower case “v” (as in Victor).
- This object must be in every file used or created by the gEDA/gaf tools.
- The format of the first version field is YYYYMMDD.
- The version number is not an arbitrary timestamp. Do not make up a version number and expect the tools to behave properly.
- The “version of gEDA/gaf that wrote this file” was used in all versions of gEDA/gaf up to 20030921 as the file formats version. This field should no longer be used to determine the file format. It is used for information purposes only now.
- Starting at and after gEDA/gaf version 20031004, the `fileformat_version` field is used to determine the file format version. All file format code should key off of this field.
- `fileformat_version` increases when the file format changes.
- The starting point for `fileformat_version` was 1. The current file format version is 2.
- fileformat version is just an integer with no minor number.
