Notes - RSS description in the built-in template is changed from full .Content to .Summary. This is a somewhat breaking change, but is what most people expect from their RSS feeds. If you want full content, please provide your own RSS template. - The deprecated .RSSlink is now removed. Use .RSSLink. RSSUri is deprecated and will be removed in a future Hugo version, replace it with an output format definition. - The deprecated .Site.GetParam is now removed, use .Site.Param. - Hugo does no longer append missing trailing slash to baseURL set as a command line parameter, making it consistent with how it behaves from site config. #3262 Enhancements - Hugo 0.20 is built with Go 1.8.1. - Add .Site.Params.mainSections that defaults to the section with the most pages. Plan is to get themes to use this instead of the hardcoded blog in where clauses. #3206 - File extension is now configurable. #320 - Impove markdownify template function performance. #3292 - Add taxonomy terms’ pages to .Data.Pages #2826 - Change RSS description from full .Content to .Summary. - Ignore "." dirs in hugo --cleanDestinationDir #3202 - Allow jekyll import to accept both 2006-01-02 and 2006-1-2 date format #2738 - Raise the default rssLimit #3145 - Unify section list vs single template lookup order #3116 - Allow apply to be used with the built-in Go template funcs print, printf and println. #3139
