Language Sitemaps for TranslatePress v0.3.3

• Fix the silent pre-init dead window of the "Manage License" trigger in the
  plugins list: clicks before the EDD SL SDK footer script has executed now
  show the core spinner state and open the license modal as soon as the SDK
  is ready (GH-2).

Language Sitemaps for TranslatePress v0.3.2

• Add the Update URI plugin header so WordPress only accepts updates for
  this plugin slug from the isla-stud.io store, never from wordpress.org
  lookalikes.

Language Sitemaps for TranslatePress v0.3.1

• Rename the display name to "Language Sitemaps for TranslatePress". The
  technical slug, plugin folder, and text domain stay
  localized-sitemap-indexes.

Localized Sitemap Indexes v0.3.0

• Add EDD Software Licensing SDK integration so copies installed from the
  isla-stud.io store receive automatic plugin updates.

Localized Sitemap Indexes v0.2.0

• Add wp localized-sitemaps list-indexes for operational endpoint visibility.
• Expand cache invalidation hooks for sitemap-related option lifecycle changes.
• Add activation and uninstall lifecycle housekeeping for plugin cache metadata.
• Add extension filters for translated URLs and generated sitemap entries.
• Build out public-repository tooling: Composer scripts, PHPCS, CI, contribution
  templates, release ZIP build, and translation template generation.
