Features 🏎️

#3477 - Implement and enable shard diff transfer, greatly improve shard transfer speed on node recovery
#3777 - Role-based access control with JWT
#3976, #4049, #4065 - Add support for byte vectors, represent your vectors as float32 or uint8

#3420, #3938 - Greatly improve write performance while creating a snapshot of a large collection
#3962, #3971 - Report pending optimizations awaiting an update operation in collection info
#3998 - Improve indexed_only reliability on proxy shards
#3798 - Make shard diff transfer fall back to streaming records
#3784 - Cancel shard transfers when the shard is deleted
#4037 - Improve sparse vectors search performance by another 7%
#3982 - Build Qdrant with a single codegen unit to allow better compile-time optimizations
#4052 - Remove vectors_count from collection info because it is unreliable. Check usage of this field before upgrading
#3803 - Remove shard transfer method field from abort shard transfer operation

#3990 - Fix potentially losing points on crash
#4034 - Fix potentially losing points on segment flushing
#4057 - Fix potentially losing points by improper moves between segments when recovering WAL
#4058 - Fix segments not being flushed properly with rapid sequential optimizations
#3995, #3996 - Fix read ordering of segments to prevent missing points just being moved
#3975 - Fix consensus operations getting stuck if they timed out
#3905 - Fix collection creation if files were left behind on disk
#4029 - Fix collection deletions conflicting with concurrent collection creation
#3991 - Fix arbitrary path traversal when uploading snapshots with created collection names
#4033 - Do not allow symlinks in snapshot archives
#4047 - Fix recommendation API for sparse vectors
#3965 - Fix discovery search with sparse vectors over gRPC
#3928 - Stabilize vector normalization, prevent renormalizing multiple times breaking data consistency
#4054 - Fix incorrect ordering when using order_by across multiple nodes
#4067 - Fix timeout being ignored when dropping segment data, potentially leaving them behind forever
#3980 - Internally forward operations with wait=true during shard transfers
#3945 - Keep jemalloc only for amd64 and aarch64 to fix build failures
