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.
