• [fea] Added support for exponential numbers in SQL parser
• [fea] Allow to switch index type (from array to scalar and from scalar to array) for empty namespaces via UpdateIndex interface

Vector indexes

• [fea] Added optional built-in auto-embedding cache with hybrid (RAM+disk) structure
• [fea] Optimize single modification requests for HNSW indexes with enabled multithreading option. Now they have the same performance as HNSW-indexes with disabled multithreading
• [fix] Fixed AVX512 implementation of L2 distance calculation for some specific dimensions count
