Tiki-Flavored Markdown
New in Tiki25 is an option to use Tiki Flavored Markdown, which is essentially GitHub Flavored Markdown (GFM) with additional syntax, which itself is essentially CommonMark with additional syntax, which itself is a standardized Markdown.
GFM is a strict superset of CommonMark. All the features which are supported in GitHub user content and that are not specified on the original CommonMark Spec are hence known as extensions, and highlighted as such.
CommonMark is a "A strongly defined, highly compatible specification of Markdown": https://commonmark.org/
It is since a few years, the de facto standard for textual syntax.
Why did Tiki move to this?
Tiki has always supported Open Standards.
History
When Tiki started in 2002, there was no standard for textual syntaxes. So the Tiki community, like other wiki engines just invented a syntax.
In 2006, wiki engines got together to elaborate a standard: http://www.wikicreole.org/
And Tiki was on board with moving to a standard:

Some believed that WYSIWYG editors would make this need go away. We didn't see how that was possible:
In 2019, Tiki20 added the possibility to add CommonMark to a section of a page: PluginMarkdown
In 2022, Tiki25 added the possibility to add Tiki Flavored Markdown by default to all content.
