|

For more indormation about SatNOGS please visit our [site](https://satnogs.org/).
|
||||
|
||||
## Release Policy
|
||||
The `gr-satnogs` OOT module uses the `major.api-compatibility.minor`
|
||||
versioning scheme.
|
||||
is used by the [satnogs-client](https://gitlab.com/librespacefoundation/satnogs/satnogs-client), so the release and versioning policy is based on how the
|
||||
satnogs client is affected by the changes on the `gr-satnogs` software.
|
||||
|
||||
* Minor changes, bug fixes or improvements that do not affect in anyway
|
||||
the `satnogs-client` advance the `minor` version.
|
||||
* The `api-compatibility` indicates changes that require modifications on `satnogs-client` but do not brake the backwards compatibility (e.g a new satallite decoder). In other words,
|
||||
the `satnogs-client` should continue to operate normally without any modifications.
|
||||
Changes on `satnogs-client` should be performed only to integrate the new features.
|
||||
* `major` version advances when the changes break backwards compatibility with
|
||||
the `satnogs-client`.
|
||||
|
||||
For every release change a tag with the corresponding version is created.
|
||||
Releases can be retrieved by the [tags](https://gitlab.com/librespacefoundation/satnogs/gr-satnogs/tags) page.
