v0.21.0

What's Changed

🌐 This release adds the ground work for indexing stars and quads by HEALPix index number, adding the additional functionality to get the neighbouring pixels to any HEALPix pixel for both the NESTED and RING schemes.

v0.20.0

What's Changed

⚡ The main solve function is now 10× faster, a 90% reduction in runtime, without any loss in accuracy or precision, whilst the API remains unchanged.

Further indexing improvements coming soon will improve performance even further, pushing the solve down to a sub-millisecond solve time.

v0.17.0

What's Changed

🔭 This release adds improved support for the HEALPIx convention, in native Go lang. This paves the way for subsequent releases to be able to provide an offline first indexed solution to plate solving utilising the GAIA DR2 & DR3 catalogs.

It's worth mentioning that a small refactor also provides a positive improvement to the plate solving accuracy.
