With SMF 2.1 Beta 1 was added credits tag

<credits url="..." license="..." copyright="..." title="..." />
And this was shown in credits page:
<a href="URL">TITLE OR MODNAME: MODVERSION</a> | LICENSE | COPYRIGHT
With SMF 2.1 Beta 3 was added url of license

<credits url="..." license="..." licenseurl="..." copyright="..." title="..." />
And this was shown in credits page:
<a href="URL">TITLE OR MODNAME: MODVERSION</a> | <a href="LICENSEURL">LICENSE</a> | COPYRIGHT
And now... can be added url of copyright?
<credits url="..." license="..." licenseurl="..." copyright="..." copyrighturl="..." title="..." />
And this will be shown in credits page:
<a href="URL">TITLE OR MODNAME: MODVERSION</a> | <a href="LICENSEURL">LICENSE</a> | <a href="COPYRIGHTURL">COPYRIGHT</a>
For example, I could add url to my mods
https://custom.simplemachines.org/mods/index.php?action=search;author=242014 or another personal webpage.
This require to increase size of the field
credits of table
smf_log_packages in database (now is
varchar(255)).
If my credits in package-info.xml is
<credits url="https://custom.simplemachines.org/mods/index.php?mod=2507" license="Creative Commons Attribution 3.0 Unported License" licenseurl="https://creativecommons.org/licenses/by/3.0/" copyright="2010-2017, davidhs" />
the content of field
credits of table
smf_log_packages is
{"url":"https:\/\/custom.simplemachines.org\/mods\/index.php?mod=2507","license":"Creative Commons Attribution 3.0 Unported License","licenseurl":"https:\/\/creativecommons.org\/licenses\/by\/3.0\/","copyright":"2010-2017, davidhs","title":""}
