    • Fix for building with external OpenSSL in non system location. Fixes issue #92502, r43338.

  • Proof
    • Import patch #43245 fixing an issue with forcing local copies of files before merging (bit not always honored).
    • Import patch #43295 to remove dependencies of netx on xrootd-related internal headers (the patch also removes external support for xrootd versions older than 4 years)
    • Import patch #43107 to add the possibility to force submerging at node level, i.e. one submerger per physical machine; in this way the network traffic can be minimized, for example when merging large output files.

    • Import patch #43440 fixing an issue with the username used to access a remote file in the xproofd daemon. Fixes a problem when retrieving files from workers where the username is different, e.g. PoD on gLite.

  • QT
    • Repair generation of qtcint (see the forum post #13636.
