Performance improvements in notes and links functions
15 Sept 2024 (in calibre source)
The performance of the template functions get_note(), has_note(), and get_link() have been improved. The improvement is especially visible when using these functions in composite columns and template searches. The amount of improvement depends on the number of items in a column. For example, when using a library with more than 10,000 authors, performance of a template search looking for authors with links improved by 20 times.
The improvement is less visible with column icon rules because these are computed when visible on the screen rather than when used in some other operation.
