 textmate2 2.0-beta.1 is now available:
 <http://blog.macromates.com/2014/yosemite/>. It is supposed to have better
 support for Yosemite. After upgrading to Yosemite, I noticed that the
 current version of textmate2 (2.0-alpha.9561) has some irregularities. For
 example, the "Go to file" popup window shows file icons but no file names.
