# What’s new in cuvarbase¶

• 0.2.0
• Many more unit tests for BLS and CE.
• BLS
• Now several orders of magnitude faster! Use use_fast=True in eebls_transit_gpu or use eebls_gpu_fast.
• Bug-fix for boost-python error when calling eebls_gpu_fast.
• CE
• New use_fast parameter in ConditionalEntropyAsyncProcess; if selected will use a kernel that should be substantially more efficient and that requires no memory overhead. If selected, you should use the run function and not the large_run function. Currently the weighted option is not supported when use_fast is True.
• Bug-fix for mag_overlap > 0.
• 0.1.9
• Now Python 3 compatible!
• Miscillaneous bug fixes
• CE
• Run functions for ConditionalEntropyAsyncProcess now allow for a balanced_magbins argument to set the magnitude bins to have widths that vary with the distribution of magnitude values. This is more robust to outliers, but performance comparisons between the usual CE algorithm indicate that you should use care.
• Added precompute function to ConditionalEntropyAsyncProcess that allows you to speed up computations without resorting to the batched_run_constant_nfreq function. Currently it still assumes that the frequencies used will be the same for all lightcurves.
• GLS
• Added precompute function to LombScargleAsyncProcess.
• Avoids allocating GPU memory for NFFT when use_fft is False.
• LombScargleAsyncProcess.memory_requirement is now implemented.
• BLS
• eebls_gpu, eebls_transit_gpu, and eebls_custom_gpu now have a max_memory option that allows you to automatically set the batch_size without worrying about memory allocation errors.
• eebls_transit_gpu now allows for a freqs argument and a qvals argument for customizing the frequencies and the fiducial q values
• Fixed a small bug in fmin_transit that miscalculated the minimum frequency.
• 0.1.8
• Removed gamma function usage from baluev 2008 false alarm probability (use_gamma=True will override this)
• Fixed a bug in the GLS notebook
• 0.1.6/0.1.7
• Some bug fixes for GLS
• large_run function for Conditional Entropy period finder allows large frequency grids without raising memory allocation errors.
• More unit tests for conditional entropy
• Conditional entropy now supports double precision with the use_double argument
• 0.1.5
• Conditional Entropy period finder now unit tested
• Weighted variant also implemented – accounts for heteroskedasticity if that’s important
• BLS
• New unit tests
• A new transiting exoplanet BLS function: eebls_transit_gpu
• Only searches plausible parameter space for Keplerian orbit
• GLS
• False alarm probability: fap_baluev
• Implements Baluev 2008 false alarm probability measure based on extreme value theory
