Harris Geospatial[1] released IDL 8.5.1 yesterday. The release notes show a few nice additions, appropriate to a patch release version: a new FILE_MODTIME, an ::IsFoldCase method for some of the container classes, routines for handling VGroup attributes in HDF4 files, IDLnetURL::URLEncode/IDLnetURL::URLDecode methods, writing a PNG to a buffer instead of a file, and an update to the HDF4 library.

  1. Exelis VIS changed their name yesterday too. ??
