I´m very disappointed as well.
Portable version was one of the most important things to choose Enpass over other Password Managers. Now you leave me out in the rain for months.
I would be really glad to hear at least about a release date for a portable v6.0 until end of march. Otherwise I will re-think my choice again, probably try Bitwarden.
But I won´t go away happy, as you´re doing a great job (besides the portable version...)!
