v1.1.0 — Schema mapping by category & post type

Major feature: configure JSON-LD type per category (with tree inheritance) or per post type from Settings → Lean SEO. No more per-post manual selection for hundreds of posts.

Adds 6 reusable schema helpers for CPT plugins (Event, DefinedTerm, JobPosting, PodcastEpisode, VideoObject, Person) callable from the lean_seo_jsonld_graph filter.

Article types extended with OpinionNewsArticle, AnalysisNewsArticle, ReportageNewsArticle, BackgroundNewsArticle, ScholarlyArticle, Report.

See CHANGELOG.md for full details.

v1.0.3 — Breadcrumbs shortcode

Adds [lean_seo_breadcrumbs] shortcode for embedding breadcrumbs in posts, pages, widgets, or Gutenberg shortcode blocks. Supports separator and class attributes.

v1.0.2 — Optional auto-inject breadcrumbs

Adds optional auto-inject of breadcrumbs before post content via the_content filter. Drop-in replacement for SmartCrawl/Yoast breadcrumb injection without theme changes.

Enable: add_filter( 'lean_seo_auto_inject_breadcrumbs', '__return_true' );

Off by default — themes that already call lean_seo_breadcrumbs() remain unchanged.

v1.0.1 — Live length counters in admin

Live char counters with color-coded feedback (green within optimal range / orange suboptimal / red over hard limit) for SEO title and meta description. ~30 LOC inline JS in admin only — frontend remains 100% JS-free.

See CHANGELOG.md for details.
