  1. Overview
  2. Versions

GOBL follows semver and Go Module Versioning best practices for all code based projects. Versions require v to be in front of the semver, for example: v0.18.0. When deciding what type of release to make, we take in the following considerations for each level:

  • Patch - typically a bug fix or change to documentation with no expected side effects.
  • Minor - significant changes that must not alter existing functionality. Adding support for a new region or support for a new type of structure are good examples. While we’re still developing v0, changes may be more significant.
  • Major - changes that will break previous implementations and should not be considered compatible. Once we hit the v1 milestone, our objetive is to try and avoid major releases as much as possible.

JSON Schemas created by GOBL use a simplified approach and only include the “major” version in sources. A few observations:

  • Schema versions match GOBL major versions.
  • GOBL v0 releases will use draft-0 in schemas for more closer alignment to JSON Schema expectations.
  • Complete GOBL Schema URLs include the version in the URL, e.g.: https://gobl.org/draft-0/envelope or https://gobl.org/v1/envelope.
  • Patch and minor releases of GOBL may add new fields or alter descriptions, but must be 100% backwards and forwards compatible inside the same major version. Most schema definitions allow additional properties, which simplifies this task.
