Using upd 2.x.x is not working behind a proxy due to package-json not supporting this setup.
The recommended fix there was to update "got" to support proxies out of the box.
sindresorhus/package-json#43
directing to
sindresorhus/package-json#22

Since the update of yargs to ^17
upd is only working on node >=12
since yargs is targeted for that node version

using upd on node < 12 causes an error in yargs stating that node >=12 is required

last upd version running on node below 12 is 2.7.7

upd is really a great tool!
and it is great that the versions can be updated automatically (= enter 'upd' in the command line) . But sometimes there are modules you exactly want a concrete version, and you do not want this version to be updated. But all the Versions of the other modules should still be updated automatically.
Of course, you can handle this in the command line, but then you always have to remember which versions should be updated and which not. So it would be nice to write it down in a config file, then u can always do the complete update (= enter 'upd' in the command line) and do not have to worry about versions, that should not be updated.
And another benefit of that config file would be, that you can comment, why exacly the choosen version is used.

Thanks ;)

Problem

When running upd it removes closing brackets of object in arrays if it's not the last one.
