Starting with LabWindows/CVI 8.0, major versions are released around the first week of August, to coincide with the annual National Instruments conference NI Week, and followed by a bug-fix release the following February.
In 2009, National Instruments started to name the releases after the year in which they are released. The bugfix is called a Service Pack (for instance, the 2009 Service Pack 1 release was published in February 2010).1
