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.
