Aimy Sitemap v41.0 allows to set a custom retry limit for Aimy Sitemap's crawler and uses a modernized storage format for periodic crawling data (PRO feature).
New Feature for Aimy Sitemap's Crawler: Retry Limit / Retry Delay
When things go wrong on your webserver during a crawl, i.e. because the web service or the used database server is restarted, Aimy Sitemap's crawler can now retry to crawl a previously failed resource for a customizable amount of times ("Retry Limit" option).
Besides that, an additional delay may be set which will make the crawler wait an extra amount of time before starting its retry ("Retry Delay" option).
Thanks to Andrés Restrepo for suggesting this feature and for testing the release candidate versions!
