Lucene 8.10 Release Highlights

• Performance improvements for faceting, including a new protected API to control which fields are counted for drill-down during drill sideways, and optimized drill sideways iterating
• Multi-valued fields are now supported in numeric range facet counting
• RegexpQuery's detection of adversarial (ReDoS) regular expressions is improved, catching exotic cases that it missed before, and throwing TooComplexToDeterminizeException
• Speedup for computing the leading prefix and trailing suffix from an Automaton, and for managing powersets during determinize
• Speedups for stored fields retrieval
• ForceMerge will now merge any number of segments at once, making it much faster in many cases
• Compression improvements for docvalues storage
• Added new analyzer for Telugu
• Near-real-time readers opened from an IndexCommit can now sort their leaves
