KeepExistingVersion

KeepExistingVersion

is an option for PacletInstall and PacletInstallSubmit that specifies whether an older version of a paclet should remain installed when a newer one gets installed.

Details

  • Possible settings include:
  • Truealways keep existing versions when a new version is installed
    Falseuninstall an existing paclet if the new one has identical requirements
  • When a paclet is installed, the default behavior is to uninstall any older paclets with the same name and requirements (i.e. "WolframVersion", "SystemID" and "ProductName" values in the PacletInfo.wl file).
  • KeepExistingVersionTrue prevents older versions of a paclet from being uninstalled when a newer one is installed.
  • You can use KeepExistingVersionTrue to keep an older version of a paclet around in case you decide to uninstall the newer one.
  • Although KeepExistingVersionTrue allows older versions to remain installed, newer versions of a paclet are always used in preference to older ones.
