VIP v1.2.3

• Fixed missing hciplot during installation;
• Minimum version required for exoplanet data challenge - phase 2.

VIP v1.2.2

• Added KLIP and LOCI Forward Model Match Filter algorithms (thanks @chdahlqvist);
• Added new bad pixel correction algorithm for IFS data (leveraging the radial expansion of the PSF for better identification of bad pixels);
• All PCA functions can now run PCA-ADI channel per channel for input 4D IFS cube (i.e. without necessarily using SDI);
• New exclude_negative_side_lobe option for pca_grid (as the negative side lobes can bias the inferred SNR, hence the optimal number of principal components).

VIP v1.2.1

• frame_shift: improved frame shifting with 'vip-fft' method: sub-px and integer parts of the shift done separately
• cube_inject_companions: better treatment of radial transmission when provided + new optional argument radial_gradient
• Tutorial 5 update

EDIT: pip installation cannot interpret requested version of hciplot. The latter must be installed manually. This will be fixed in the next release.

VIP v1.2.0

• Improved FFT-based image shifting algorithm
• Updated fake planet injection routine (new options + improved internal shift procedure)
• Added information about more high-contrast imagers in config module
• Improved description for fitting functions

VIP v1.1.3

• skimage-based rotation fixed (bug for versions >~0.19 solved by limiting version to <=0.18.3)
• lighter tutorials => lighter package => ~6x faster import of VIP
• opencv dependency added to avoid bug in automatic tests
• flake8 integration
• automatic coverage and documentation updates upon accepted pull requests

VIP v1.1.2

• Modified protect_psf into protect_mask keyword, for consistency throughout all bad pixel correction routines
• Minor bug fixes for bad pixel correction in concentric annuli
• Updated tutorial bad pixel correction example
• Updated requirements for hciplot to solve new backward incompatible update of jinja2 (used in panel, in turn required in hciplot)
• Moved opencv to developer mode requirements
• Typo fixes in tutorials

VIP v1.1.1

• Major documentation update, including tutorials;
• README update;
• Bug fix in bad pixel correction routine (case frame_by_frame=False);
• Convention update regarding new sizes when rescaling images with frame_px_resampling (for bijectivity);
• Fixed Radon-transform based centering algorithm.

VIP v1.1.0

• Major revamp of the package:

1. creation of a 'fm' module for all forward-modeling related routines (disk model creation, negfc, fake companion and fake disk injections);
2. creation of a 'psfsub' module including all PSF modeling and subtraction post-processing algorithms;
3. creation of a 'invprob' module including andromeda, and to host future inverse-problem approach based algorithms;
4. fixed relative imports in package to match the new structure.

• Additional automatic tests for stim map, fake disk injection, (de)rotation, image scaling
• Improvement and bug correction of the phase function for the disk scattered light forward model tool
• New bad pixel correction algorithm based on kernel-interpolation;
• Updated write_fits to also allow for multiple-extension fits files to be written;
• Added border_mode option to all recentering functions;
• half_res_y option added to sigma clipping algorithms (i.e. made it compatible with image-slicer IFUs);
• Photutils and numpy deprecation warning fixes;
• Routine descriptions adapted for compatibility with sphinx documentation;
• Updated matplotlib version requirement to avoid bug with the latest mpl version (as of 02/2022);
• Default start method for multiprocessing set manually to 'fork', since it was changed to 'spawn' as default starting from python 3.8 (leading to bugs in all routines using multiprocessing);
• Updated default flux range explored by grid search negfc.

VIP v1.0.3

• Addition of new image (de)rotation options to mitigate Gibbs artefacts when rotating an image with sharp signal transitions
• Fix for injection of shifted psf images with FFT-based method
• Fix for multiprocessing in frame differencing function
• Fix for multiprocessing (de)rotation of images
• Addition of some automatic tests to the pytest suite
• Fix for automatic SDI test
• Modification of the automatic RDI test
• Modification of the default waiting time to open ds9 window, to avoid a non-response bug.

VIP v1.0.2

Two major changes in default VIP behaviour:

1. Change of default method for image shift, scaling and rotation throughout VIP: switched from opencv interpolation-based methods to FFT-based methods (imlib='vip-fft').
2. Change of VIP convention regarding center of even-sized images: dim/2 (zero-based indexing) instead of dim/2-0.5. For odd-size images, the convention is identical. Now, in either cases the centroid is assumed to fall exactly on a pixel.

Readme and andromeda routines were adapted to reflect the above change in convention.
