PmWiki 2.5.7 released

Hello. PmWiki version 2.5.7 was published today, and is available at:

   https://www.pmwiki.org/pub/pmwiki/pmwiki-2.5.7.tgz
   https://www.pmwiki.org/pub/pmwiki/pmwiki-2.5.7.zip
     svn://www.pmwiki.org/pmwiki/tags/latest


This version includes updates for PHP8, some bug fixes, and 
optimizations.

A new variable $IsLocalhost will be true when the wiki server is on the 
same computer as the browser, this can simplify configuration for 
mirrored wikis.

The PmLib JavaScript helper library was refactored for easier usage.

With tables, if the first and last rows have only header cells, they 
will be moved to <thead> or <thoot> elements. This helps with styling, 
sorting, filtering, and printing.

The Sortable tables function was rewritten, it now supports complex 
headers and footers with rowspan and colspan, and a new way to define 
column sort types (numeric, alphabetical, date, or no sorting).

A CSS class "center" was added, and link colors in the %note% style will 
inherit the note color.

The documentation was updated.

Thanks,
Petko
