Excellent.  I noticed the target for issue #250 is 1.2.0.  Is that still
the current target, and if so, do you have any sense at this point
roughly when this would be released?

Also, do you yet have some intuition as to what kind of speed
improvement should be expected?

For my purposes, constructing the XTID filter via the API rather than
using the parser makes a lot more sense as well as being much faster,
but I'm sure other people will benefit from your investigation. :)

Thanks,
Jason.
