Description

<alikins> in the plugin api, is there an equilivent to `from pulpcore import __version__ as pulp_version`  to get the pulpcore version?
<alikins> idealy without invoking 'packaging' or 'distsetutools' etc
* x9c4 has quit (Quit: Leaving)
<dkliban> alikins: https://github.com/pulp/pulpcore/blob/master/pulpcore/__init__.py#L1
<dkliban> like that?
<dkliban> it's not part of the plugin api though

NOTE: It likely affects the release automation, make sure to update that.

Expose pulpcore_version to plugin writers

Give plugin writers a way to access the pulpcore version. This is possiblyuseful in case they want to support more than one version of the plugin API at the same time.

Are there required any modifications from the plugin writer's perspective?

I believe, the answer to my question is Yes. Even though it is somehow said in the changelog entry (Added a constant holding the pulpcore version which can be imported by plugins - pulpcore.plugin.pulpcore_version), it could be announced globally at pulp-dev.
