Improvements on the signature verification of Trusted Lists:
- Automatically using the Member State signing certificate published in the list of lists (LOTL) for signature verification.
- If the Member State signing certificate is not published in the LOTL, the supposed signing certificate can be selected from the file system.

Improvements on the Check against trusted lists function:
- Using the CA QC/PKC certificates listed in the Trusted List as Trust Anchors, automatically downloading the freshest Trusted List based on the country code of the certificate issuer.

Improvements on the certificate viewer component:
- Using certification path builder wizard to build and display the upper hierarchy above CA services listed as accredited/supervised in a Member State Trusted List. Using the intermediate and root certificates from the signature, downloading the missing certificates using the URLs from the AIA extension and performing cross-certification as a last resort.

Improvements on the Content audit function of the LOTL:
- The report now includes the country code and name of the Member State whose certificate is missing from the PointersToOtherTSL/OtherTSLPointer element.
