We're glad to announce that Verilator 4.000 is now in beta test and will be formally announced at OrConf 2018

The git tree now contains the beta, please give it a try, and enjoy the main new feature of multithreaded simulation!

• If your git repo was using the 'master' branch (the default) as upstream you need do nothing, you'll now get the 4.000 sources.

• If you were using the git 'develop-v4' branch, that branch is now merged into 'master'. 'develop-v4' was deleted. Pulling from a branch that has 'develop-v4' as upstream may give a "Your branch is based on 'origin/develop-v4', but the upstream is gone" or "Your configuration specifies to merge with the ref 'refs/heads/develop-v4' from the remote, but no such ref was fetched" error. You need to do this:

  git branch --set-upstream-to=origin/master

• A new 'v3/devel' branch was made pointing to the previous origin/master (with Version 3.xxx) and will only be developed further if another 3.xxx release is required due to a serious issue.
