0.6.0

indexnowkit/sitemap is optional again (docs/spec/16, wave C): the bundle suggests it instead of requiring it.
Configuration tree, command names, service ids and everything else do not change.

Changed

• indexnowkit/sitemap is no longer installed automatically. If you use indexnow:sitemap, run
  composer require indexnowkit/sitemap; otherwise, after composer update, the command reports that the package is
  missing and exits with code 1. Requires indexnowkit/core ^0.5.1.
• Without the package: indexnow:sitemap is Command\SitemapNotInstalledCommand (same name, every argument and
  option accepted and ignored, prints indexnowkit/sitemap is not installed: composer require indexnowkit/sitemap,
  exit 1); indexnow:check prints sitemap: not installed (composer require indexnowkit/sitemap), or sitemap: not installed, the sitemap block in the configuration is ignored (…) when the yaml still has a sitemap block; that
  block compiles without validation; the services indexnowkit.sitemap_config, indexnowkit.sitemap_reader,
  indexnowkit.check.sitemap_spool and indexnowkit.console.sitemap do not exist. Nothing is logged at boot or on
  a request.
• IndexNowKitBundle, DependencyInjection\IndexNowKitConfiguration and DependencyInjection\IndexNowKitLoader
  take ?bool $sitemapInstalled = null (null = detect; tests pass false). IndexNowKitConfiguration::build() is an
  instance method now; the sitemap node and services moved to DependencyInjection\SitemapServices, the only
  wiring that reads IndexNowKit\Sitemap\*. Only relevant if you call these classes yourself.
