Changelog
=========
2.1.0
-----
* :py:func:`vsfieldkit.prepare_nnedi3_chroma_upsampler` can now use the znedi3
  or nnedi3cl plugin in addition to plain nnedi3 as before.
* Add compatibility with VapourSynth>=63 Python wrapper, broken due to renamed
  ``PresetVideoFormat`` enum.

2.0.1
-----
Fix :py:func:`vsfieldkit.resample_as_progressive`'s ``avoid_chroma_shift``
option. It was having an opposite effect from intended and resampling with even
lossier shift.

The new method avoids the subsampling grid altogether by resampling the Cb and
Cr planes separately, avoid unnecessary re-siting even with nearest-neighbor
resampling.

New Features
^^^^^^^^^^^^
* Interlacing! Targeting deinterlacer testers and engineers in the broadcast
  space who've been instructed to avoid soft telecine. Two new functions:

  * :py:func:`vsfieldkit.telecine`
  * :py:func:`vsfieldkit.weave_fields`

* [Re]sampling kernels to supplement the out of the box vapoursynth.resize
  functions, but specialized for vsfieldkit tasks. They can be found in the
  :py:mod:`vsfieldkit.kernels` module. Includes an nnedi3 kernel-maker for use
  as a chroma upsampler.

* :py:func:`vsfieldkit.annotate_bobbed_fields` for retro-actively adding a
  property to bobbed frames noting the field (top or bottom) they came from.

* :py:func:`vsfieldkit.output_frame_inferred_y4m` for outputting yuv4mpeg2
  (y4m) data with metadata derived from the first frame's properties, allowing
  for interlaced output, SAR, and chroma siting as available.

Changed APIs
^^^^^^^^^^^^

* :py:func:`vsfieldkit.resample_as_progressive` ``kernel`` argument renamed
  to ``subsampling_kernel`` for clarity. ``upsampling_kernel`` argument added.
  It also now fakes luma-co-sited chroma during upsampling to avoid lossy
  chroma re-siting.
* :py:func:`vsfieldkit.resample_as_progressive` and
  :py:func:`vsfieldkit.upsample_as_progressive` now default to Spline 36 for
  any chroma subsampling or upsampling using the new 
  :py:func:`vsfieldkit.kernels.resample_chroma_with_spline36` .
* :py:func:`vsfieldkit.upsample_as_progressive` now has
  ``upsample_horizontally`` argument. Defaults to ``False``.
  :py:func:`vsfieldkit.resample_as_progressive` uses this as ``True``
  internally.

1.1.0
-----
* :py:func:`vsfieldkit.fill_analog_frame_ends` allows overriding the pre-fill
  mode and gives better error messaging when the fillborders plugin is missing
  the requested mode. The default mode is now ``"fillmargins"`` instead of
  ``"fixborders"`` in order to work with the release version of fillborders.
* :py:func:`vsfieldkit.fill_analog_frame_ends` works with progressive clips
  cropped by factors smaller than interlaced subsampling.
* :py:func:`vsfieldkit.fill_analog_frame_ends` more compatible with code
  autocompletion via removal of decorators.
* :py:func:`vsfieldkit.scan_interlaced` can brighten newly-scanned fields via
  new ``attack_factor`` argument.

1.0.2
-----
* :py:func:`vsfieldkit.fill_analog_frame_ends` will now look for EdgeFixer
  plugin first, followed by ContinuityFixer plugin as before. Having one of the
  two plugins is required.

1.0.1
-----
* Adds :py:func:`vsfieldkit.fill_analog_frame_ends` for cleaning the half-line
  black bars at the top and bottom of analog video.

Output Change:

* :py:func:`vsfieldkit.bob` now defaults to shifting according to the field's
  position. Feature added for completion, but it's also deprecated in favor of
  :py:func:`resize.Bob` in VapourSynth R58+.

Version 1.0.0 was yanked for an immediate bug fix.

0.3.0
-----
* New functions for re-interpreting progressive frames with interlaced sub-sampled chroma:

  * :py:func:`vsfieldkit.resample_as_progressive`
  * :py:func:`vsfieldkit.upsample_as_progressive`

* Adds phosphor decay simulation for :py:func:`vsfieldkit.scan_interlaced`


0.2.0
-----
Adds :py:func:`vsfieldkit.bob` deinterlacer.

0.1.0
-----
First release. :py:func:`vsfieldkit.scan_interlaced` and some nifty utilities.
