ISSUES

1. [Status update] IronPython 2.0 Beta3 has memory leak in WCF programming
http://ironpython.codeplex.com/workitem/17331
User slide_o_mix has updated the issue:
Status has changed from Active to Closed with the following comment, 

"Can't reproduce"-----------------

2. [Status update] 1.1.3: AttributeError in property getter (1.1.2 only)
http://ironpython.codeplex.com/workitem/18618
User slide_o_mix has updated the issue:
Status has changed from Active to Closed with the following comment, 

"Works in 2.7.1"-----------------

3. [New comment] Quoting in MSBuild files
http://ironpython.codeplex.com/workitem/20262
User slide_o_mix has commented on the issue:

"Jeff since you've recently redone the build can you double check this?"-----------------

4. [New comment] Ctl-Z doesn't throw EOF error in raw_input()
http://ironpython.codeplex.com/workitem/22140
User slide_o_mix has commented on the issue:

"The issue is in PythonFile::ReadLine

// Read characters up to and including a '\r\n', converted to '\n' (or until EOF or the given size, in
        // which case the string will not be newline terminated).
        public override String ReadLine(int size) {
            StringBuilder sb = null;
            // start off w/ some text
            if (_bufPos >= _bufLen) ReadBuffer();
            if (_bufLen == 0) return String.Empty;

That last item should probably be:

if(_bufLen == 0) throw PythonOps.EofError(string.Empty);

I improved the error message in 7f9fc2a."
