Can you elaborate more on what the feature is about and also how should be implemented, on a high-level basis?

@trygvis Could you provide a description of the problem, and what would be involved in supporting GitLab?

[trygvis]

@alexjpwalker @lolski It would be more or less the same as the Github (deploy_github). Gitlab supports the same semantics as Github of creating releases with attachments based on Git tags.

Got it. Thanks.
