Leanderson. Actually, we never released a 3.0 version of netCDF. The earliest netCDF-3 release was version 3.3 in 1997, and the release announcement included this question and answer: Q: Why is the new version named 3.3 instead of 3.0? A: It's just a number. We made available some prereleases of netCDF-3 and needed to change some interfaces as the result of testing. 3.3 is the first version of netCDF-3 made available for general release. There will almost undoubtedly be follow-on versions (3.3.1, 3.3.2, ...) as we incorporate feedback and bug fixes into the release, but the current release has already undergone extensive testing. The format did not change, so the latest version 3.6.2 (and in fact all future versions) will still be able to read and write older netCDF files created with earlier versions of the software. --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: IWD-582006 Department: Support netCDF Priority: Normal Status: Closed
