What’s new and what’s coming

New tools and improvements, newest first. Day-to-day platform notes are on platform updates.

Changelog

Nov 2026

  • NewA new look — a cleaner design, a tool finder on every page (press / or Ctrl+K) and light and dark themes that follow your system.
  • ImprovedEvery tool rebuilt — all 23 tools rewritten on the new design and checked against the VCF 9.0 and 9.1 documentation, with share links and many fixes to what they generate.
  • ImprovedVCF JSON builder — checks that follow the release you pick, including the 9.1 fields, and checks on every value before you export.
  • ImprovedDiagram templates — corrected for VCF 9.0 and 9.1, with the seven networks from the VCF blueprint.

  • ImprovedSecurity — share links and imported files are checked strictly, and generated scripts keep passwords off the command line.

Oct 2026

  • ImprovedSecurity hardening — imported files, saved designs and the blog feed are now treated strictly as data; the ESX boot server hashes the root password.
