This release brings new updates and bug fixes to several components including Zip, Ftp, ftp,
Saml, and Pdf.

but after installation the zip.dll
the ComponentPro.Zip.dll for net 4.0 -> 4.7x (production) file is 184.108.40.206
date of modification : 24/11/2018
in fact, even if the setup programme is named "UltimateStudio-Pro_Premium_220.127.116.11.exe" , most of the dll are 18.104.22.168 versions. only one dll is 22.214.171.124 : ComponentPro.Encryptor.dll. All other are 126.96.36.199
