Version 4.2.0 (Public release)
------------------------------

 * Documentation updates

Version 4.1.8 (Paranal release)
-------------------------------

 * Removed ncycles parameter from visir_img_reduce and visir_spc_reduce. It is
   still available for visir_util_repack. As it works per nod-cycle it is not
   very useful for the full reduction recipes.
 * Added planelimit parameter to limit the number planes per nod position which
   the pipeline reduces.
 * Limited number of planes reduced for imaging science to at most 2000 to
   avoid slowing down following shorter reductions.
 * Enabled parallel processing of reduction blocks in RBS. This allows e.g.
   shorter calibration blocks to not blocked by very long burst mode
   reductions.
 * Use linearity table in automatic spectroscopy reductions.
 * Spectroscopy data is now also jitter corrected which allows using the rr
   and rl parameters to better handle extended targets.
 * Increased number of reading IO threads to improve performance of reading
   compressed files.
 * Reduced memory usage of visir_util_repack when receiving very many input
   files.
 * Improved parallelization depth of coaddition process to better handle the
   case of very few very large input files.

Version 4.1.7 (Public release)
------------------------------

 * Adapt to new data format written since February 2016.
 * Allow reduction of now commissioned Aquarius Burst mode data.
 * Updated Reflex tutorial.
 * Fix too many open file issues on some platforms.
 * Updated Reflex data association rules.
 * Tune default Gasgano display columns to Aquarius data.
 * A few usuability improvements for Reflex Imaging GUI.
