Published Feb 1, 2024

Product: EDI platform

You can now use Stedi to read and write any transaction set from all releases in the 1980s-era X12 Version 2:

- [`002001`](https://www.stedi.com/edi/x12-002001) | Release year: 1987

- [`002002`](https://www.stedi.com/edi/x12-002002) | Release year: 1988

- [`002003`](https://www.stedi.com/edi/x12-002003) | Release year: 1988

- [`002040`](https://www.stedi.com/edi/x12-002040) | Release year: 1989

With this update, Stedi now has complete coverage of all transaction sets across all releases from X12 `002001` to X12 `008040`.

Stedi also now supports custom `GS-08` Industry Identifier Codes for all X12 releases when reading and writing EDI.

Industry Identifier Codes are the 1-6 characters appended to the end of a release in the `GS-08` element – for example, `005010**UCS**` and `004010**VICS**` or `005010**X279A1**` in the X12 HIPAA standard. You can now define your own custom identifier for any transaction set as needed. Custom identifiers are helpful when trading with automotive OEMs such as Ford (which uses `002002**FORD**`) and Chrysler (which uses `002040**CHRY**`).
