SitemapMgr 1.9.0 is a maintenance and feature release.

Main fix: on some hosts the sitemap files were empty. The cause was the module's Smarty rendering being blocked by a server security policy. Rendering now works regardless of that policy. Sitemaps and the index generate reliably.

New in this release:
  - "Update sitemaps now" button.
  - Configurable automatic schedule (hourly to monthly, or manual).
  - Built-in help with cron setup steps.

Upgrade notes: existing installs migrate automatically. The schedule defaults to daily. A CmsJobManager job is created on upgrade. Automatic updates need CmsJobManager running. On low-traffic sites, add a server cron job (see the module Help for the command).
