* Verilator 4.036 2020-06-06

**    OPT_FAST is now -Os by default. See the BENCHMARKING & OPTIMIZATION part
      of the manual if you experience issues with compilation speed.

***   Configure now enables SystemC if it is installed as a system headers,
      e.g. with 'apt-get install systemc-dev'.

***   Add --waiver-output flag that writes a verilator config file (.vlt) with
      waivers to the warnings emitted during a Verilator run.

***   Support verilator_coverage --write-info for lcov HTML reports.
      Line Coverage now tracks all statement lines, not just branch lines.

***   --output-split is now on by default. VM_PARALLEL_BUILDS is set by
      default iff the --output-split caused an actual file split to occur.
      --output-split-cfuncs and --output-split-ctrace now default to the
      value of --output-split. These changes should improve build times of
      medium and large designs with default options. User makefiles may
      require changes.

***   The run-time library is now compiled with -Os by default. (#2369, #2373)

****  Support multi channel descriptor I/O (#2190) [Stephen Henry]

****  Support $countbits. (#2287) [Yossi Nivin]

****  Support $isunbounded and parameter $. (#2104)

****  Support unpacked array .sum and .product.

****  Support prefix/postfix increment/decrement. (#2223) [Maciej Sobkowski]

****  Fix FST tracing of little bit endian signals. [Geza Lore]

****  Fix +: and -: on unpacked arrays. (#2304) [engr248]

****  Fix $isunknown with constant Z's.

****  Fix queues and dynamic array wide ops. (#2352) [Vassilis Papaefstathiou]


* Verilator 4.034 2020-05-03

**    Add simplistic class support with many restrictions, see manual. (#377)

**    Support IEEE time units and time precisions. (#234)
      Includes `timescale, $printtimescale, $timeformat.
      VL_TIME_MULTIPLIER, VL_TIME_PRECISION, VL_TIME_UNIT have been removed
      and the time precision must now match the SystemC time precision. To
      get closer behavior to older versions, use e.g. --timescale-override
      "1ps/1ps".

**    Add --build to call make automatically. (#2249) [Yutetsu TAKATSUKASA]

**    Configuring with ccache present now defaults to using it; see OBJCACHE.

**    Fix DPI import/export to be standard compliant. (#2236) [Geza Lore]

**    Add --trace-threads for general multithreaded tracing. (#2269) [Geza Lore]

***   Add --flatten for use with --xml-only. (#2270) [James Hanlon]

****  Greatly improve FST/VCD dump performance (#2244) (#2246) (#2250) (#2257) [Geza Lore]

****  Support $root. (#2150) [Keyi Zhang]

****  Add error if use SystemC 2.2 and earlier (pre-2011) as is deprecated.

****  Fix logical not optimization with empty begin. (#2291) [Baltazar Ortiz]

****  Fix reduction OR on wide data, broke in v4.026. (#2300) [Jack Koenig]

****  Fix clock enables with bit-extends. (#2299) [Marco Widmer]

****  Fix MacOs Homebrew by removing default LIBS. (#2298) [Ryan Clarke]


* Verilator 4.032 2020-04-04

***   Add column numbers to errors and warnings.

***   Add GCC 9-style line number prefix when showing source text for errors.

***   Add setting VM_PARALLEL_BUILDS=1 when using --output-split. (#2185)

***   Change --quiet-exit to also suppress 'Exiting due to N errors'.

****  Suppress REALCVT for whole real numbers.

****  Support split_var in vlt files. (#2219) [Marco Widmer]
