ZFP 1.0.0

• updated the ZFP library to the new version 1.0.0
• updated dependencies

Spectral Lines Hard Limit

• Introduced a hard limit of 500 Splatalogue spectral lines that can be displayed simultaneously in the website. This has been done in order to prevent an information overload and a website slowdown. The 500 lines that are displayed will be chosen as a random subset of the larger than 500 original number of lines. Please refine your search criteria to avoid a hard limit. If the hard limit has been reached information will be displayed in the web browser JavaScript console (press F12 to view it in most browsers).
• Updated dependencies.

maintenance

• updated the two dependencies: fpzip-sys and zfp-sys crates to work with the new LLVM16 and the corresponding (newer) bindgen

cache management

• if the top FITS cache directory contains an empty hidden file .DONOTDELETE, its (the cache folder) contents will be excluded from the scheduled deletion after 30 days
• updated dependencies

Einstein bug fix

• added the missing brackets in fn Einstein_velocity_addition(v1: f64, v2: f64) -> f64

maintenance

• fixed contours updating after a frequency sub-region selection
• upgraded the main HTML code to Google Analytics 4
• updated dependencies

disk cache cleanup improvements

• replaced metadata.accessed() by metadata.created() in the automatic disk cache cleanup thread to improve the removal of old cache entries
• updated dependencies

external URL download support

• support for full FITS file downloads from within fits_web_ql when a FITS file has been opened via an external URL
• updated dependencies

Improved support for large 2D planes

• This release supports large 2D planes in FITS cubes (or standalone images), for example width = 30000, height = 20000, as long as width * height does not exceed the upper limit of uint32. If read_at() fails to read the entire 2D plane in one go, the code switches to chunked file reading (chunks set to 256KB).
• Switched the internal floating-point accumulators from float to double when calculating the spectrum. This is in order to support summing up intensities (pixels) from large-resolution planes.

automatic cache clean up

• added an automatic cache clean-up functionality (a 30-day disk cache file timeout)
• updated dependencies
