I created two release (thrift-0.6.2 and thrift-0.7.1) to fix some issues in early version (0.6.x, 0.7.x) which is used for Apache Flume. These issues have been fixed in later versions (0.8.x+) of original repo. Main change is the buffered input/output stream to improve the performance for on 0.6.x & 0.7.x, change on 0.7.x also includes 'oneway' fix (THRIFT-1447). Two new versions are created: thrift-0.6.2 and thrift-0.7.1.
