30.0.0 (2020-07-19)

Features

• check-types, no-undefined-types, valid-types: Add structuredTags setting to control whether the type and namepath portions should be checked for validity and whether such portions are required, and to let user-defined "namepath-defining" tags be added to defined types. Closes #481 (89f2ad0)
• valid-types: change allowEmptyNamepaths default to false, ensuring tags which expect names per docs will be reported (842381a)

BREAKING CHANGES

• check-types, no-undefined-types, valid-types: Drops checkSeesForNamepaths setting. Use {settings: {jsdoc: {structuredTags: {name: 'namepath', type: false, required: ['name'],}}}} instead.

Also:

1. Clarifies in more cases where a problem is specific to the mode or not
2. Reports simultaneous invalid name and type errors
3. typdef now requires allowEmptyNamepaths: false, to report empty names (as with other tags)
4. Requires a name for event and external (and extends in jsdoc mode); some tweaking of other tags per docs
