Still not great though. MinGW support is much stable now, and mswin support is added. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65239 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- NEWS | 11 +++-------- 1 file changed, 3 insertions(+), 8 deletions(-) (limited to 'NEWS') diff --git a/NEWS b/NEWS index e186b04eb8..5ec16e6f0c 100644 --- a/NEWS +++ b/NEWS @@ -411,15 +411,10 @@ sufficient information, see the ChangeLog file or Redmine * --enable=jit option is added to enable JIT. --jit-verbose=1 is good for inspection.
