    Release Notes: This release adds numerous functions, including REWGT to scale data weights by subarray and/or IF, ACLIP to do clip operations on auto­correlation data, RLCAL to solve for right-minus-left phase differences as a function of time when good source models are available, SY2TY to make TY tables from SysPower tables, RFLAG to flag data based on rmses measured over short time intervals and on deviations from the spectral average, and AFARS to extract useful parametric images from the Faraday Rotation synthesis (FARS) output image cubes.

      Release Notes: CLSMO and SNSMO have normalization controls. TVFLG has a revision of the next IF option and its image placement. TYSMO applies flag tables to the TY or SY tables on input. A new task, REWGT, applies user-specified scaling to data weights. Other changes include SOUSP to fit spectral indices from the fluxes in the source table, NOIFS to convert a multi-channel, multi-IF data base into one with a single IF, and TRUEP to fits for true instrumental polarization using data taken with rotated feeds.

          Release Notes: This release adds the new verbs ASIN, ACOS, and SIZEFILE, and the amplitude calibrator model 3C147 at C and X bands. All I/O-based components were refactored to reduce I/O bandwidth consumption. Code and parameter cleanups for FILLM. Extensive bugfixes and refactoring.

              Release Notes: Developers have developed new tasks, including TAPPE to append one version of a table to another version, TYSMO to edit and smooth system temperature tables, TYAPL to remove and/or apply system temperature corrections to uv data, FLOPM to reverse the spectral order of a data set with or without special axes for a VLA issue, and HAFIX to determine if there is a time error in the (u; v;w) values in a data set. A stand-alone program REBYTE was created to convert the byte order of whole AIPS directories.

                  Release Notes: Support was added for Mac OS X on the Intel CPU. Many new features were added, including identifying the center of sources in sub-images, 2D histograms, self-calibration of data, and data compression. Many bugfixes and code cleanups were done. Enhancements specific to the NRAO Very Large Array telescope are included.
