Re: [Openexr-user] OpenEXR 1.6.0 and CTL 1.4.0 released

[Florian Kainz]

This particular change was intended to fix a naming inconsistency in
ImfStandardAttributes.h.  I was under the impression that few, if any,
people cared about the utcOffset attribute.  Next time I'll be more
careful.

By the way, the change in ImfStandardAttributes.h affects only the
name of two functions (addUtcOffset and hasUtcOffset); the file format
has not changed.
