★★★★★ – “Unlike competitors, you can literally customize just about every aspect of SEO and Social SEO if you desire to. […] This plugin has the most complete JSON-LD markup out of any of them, so you won’t have any errors and warnings in search console for WordPress or WooCommerce sites. You can go crazy customizing everything, or you can just set and forget. There aren’t many plugins that allow the best of both worlds.” – kw11

Release Schedule

New versions of the plugin are released approximately every week (more or less). New features are added, tested, and released incrementally, instead of grouping them together in a major version release. When minor bugs fixes and/or code improvements are applied, new versions are also released. This release schedule keeps the code stable and reliable, at the cost of more frequent updates.

See release early, release often (RERO) software development philosophy on Wikipedia for more information on the benefits of smaller / more frequent releases.

Version Numbering

Version components: {major}.{minor}.{bugfix}[-{stage}.{level}]

• {major} = Major structural code changes and/or incompatible API changes (ie. breaking changes).hanges).
• {minor} = New functionality was added or improved in a backwards-compatible manner.
• {bugfix} = Backwards-compatible bug fixes or small improvements.
• {stage}.{level} = Pre-production release: dev < a (alpha) < b (beta) < rc (release candidate).
