This topic aims to collect each changes commited in the beta version in provision of the future release. It mainly concerns the "core" of amdlib, i.e., the C code library and all the amdlibXXX shell commands and their numerous options. Note that while the namesake amdlib Yorick interface, which presents simpler options and add visualization tools, should be preferred over the shell commands for the general user, reading these notes can be enlightening.

V3.0.8beta5 soon to be released as V3.0.8

• corrected regression introduced in V3.0.8beta2
• Apparently, the yorick version of amdlib still has an issue with compressed P2VM files ending in '.Z'. In this case, gunzip the culprit P2VM and retry.

V3.0.8beta2

• Fix missing checkClosureBiasRemoval calls
• a few cosmetic changes to prevent warnings when compiling with latest version of gcc.

V3.0.8beta2

• Fix support of new files extracted from the ESO archive by new HOTF_version(1.1)

V3.0.8beta1

• implement correction for phase closure bias as described in Astronomy & Astrophysics, Volume 541, id.A46. . Still waiting from acceptance from the authors of this paper (but one cannot wait forever...) Please note that, although this correction is enabled by default in the (seldom used) amdlib commandline mode, it is disabled (option -T) in the yorick amdlib program.
• A consequence is the addition of 3 new 'colums' (if the correction is applied) in the OI_VIS table of the OI-FITS files produced by amdlib. The 'columns' are named T3BIAS, T3INTERBIAS and VISCOVRI and should be normally ignored by all OI-FITS related programs.
• VISAMP (amplitude of the differential visibility) is now correctly computed.

Old note: There was a naming convention problem concerning beta packages V3.1b1 to V3.1b4 . Some have been distributed (between july 2010 and March 2011) and correspond to some previous versions of the V3.0.2. Impacted users have been warned and wrong numbered tags have been removed from the source code repository. We apologize for the inconvenience -- Guillaume
