UserPoints plugin for Community Builder

I've been writing a plugiin and have a couple of questions.
1. It seems that the version number of a plugin has to somehow conform to CB version numbering. A new plugin given a version of 1.0.0 does not install. Matching the installed CB version does install. But what degree of matching is required? How much of the version number is necessary? What is an appropriate policy for third party plugin versioning?
2. As the links between CB and UserPoints develop, a number of triggers will need to be handled. Can a single plugin handle multiple triggers? Is there any limit?
Best regards, Martin

CB plugins have <version> and <release>. They are as follows.

<version> = minimum compatible CB version
<release> = plugin version

Both are semver and should be supplied as semver. So if you're making a new plugin you'd have the below for example.

2. As the links between CB and UserPoints develop, a number of triggers will need to be handled. Can a single plugin handle multiple triggers? Is there any limit?

You can bind to as many CB triggers as you like in your plugins main PHP file.

Thanks. How do I know what is the minimum compatible CB version? Is 2.11.0 the only sensible value currently?

Generally you just set it to current stable. It's up to you though. 2.11.0 is the current stable release so yes I'd recommend setting it to that.

Thanks. It isn't really up to me, though. The current plugin requires CB to provide the onAfterUserAvatarUpdate trigger, with a first parameter that is a user object, having an id property. I want to support users who have a CB version that meets that requirement. How do I know what CB versions meet that requirement? And if I set the version to the earliest of them, will the plugin be accepted as compatible with the current version? These are questions that require knowledge of CB development.
