Version 1.13.0

Functionality/Performance Improvements and Additions

• Allow user control of the local sky subtraction window
• Implemented a resample algorithm when generating datacubes
• Sensitivity function masking and output updates
• Improve speed in ginga visualization of traces and added
  pypeit_chk_tilts. Note that this script uses an update
  of the tilts datamodel, so it will not work on older reductions.
• Fixed a bug in the variance_model calculation for combined images.

Datamodel Changes

• Removed use of the term "master", renamed to calibration frames/files.
  Default output directory for calibration frames is now Calibrations.
  Calibration frames renamed from, e.g., MasterArc* to Arc*.
• Names of associated calibration frames now written to spec2d file headers.

Dependency Changes

• Deprecate support for python 3.8 with PypeIt, allow python 3.11
• Make pypeit_show_2dspec (somewhat) backwards compatible.
• Added the option to disable strict version checking for 1d coadds.
• Start to deprecate use of os.path in favor of pathlib

Script Changes

• In PypeIt files, the 'calib' column is now always added to the pypeit
  file, regardless of whether or not you also request the 'comb_id' and
  'bkg_id' columns.
• In PypeIt files, the calibration group numbers can now be anything, as long as
  there are no more than 63 unique integers.
• Deprecated pypeit_parse_calib_id script, but improved the .calib file
  provided by pypeit_setup. The .calib file is now always written, and
  provides a direct association between input raw files and output calibration
  files. Discussed in new docs.
• Added coadd2d setup script
• Added the possibility to use dither offsets saved in the header of the science
  frames for coadding 2D spectra (dithoff must be part of the spectrograph
  metadata).
• Major quicklook updates; see documentation. ql_multislit.py deprecated.

Instrument-specific Updates

• Updates to reduction parameters for LDT/DeVeny

Hotfixes

• Hotfix to docs to ensure pypeit_loaders api doc is generated
• Hotfix for KCWI when using alignment (aka ContBars) frames for the astrometric correction.
