# Deprecations

The following deprecated items are scheduled for future removal:

C++14 compiler support

  Verilator currently requires a C++20 or newer compiler for timing, and a C++14 or newer compiler for both compiling Verilator and compiling Verilated models with –no-timing.

  Verilator will require C++20 or newer compilers for both compiling Verilator and compiling all Verilated models no sooner than May 2025. (Likely to be removed shortly after GitHub removes Ubuntu 20.04 continuous-integration action runners, which are used to test the older C++ standard).

XML output

  Verilator currently supports XML parser output (enabled with –xml-only). Support for –xml-* options will be deprecated no sooner than January 2026.
