Odaily News Ava Labs engineering director Patrick OGrady posted on the X platform that Avalanche Cortina 15 has been released. This version (V1.10.15) is backwards compatible with V1.10.0. This is optional but recommended. - Release highlights: Experimental PebbleDB support, BaseTx support based on P-Chain, and MerkleDB memory optimization. - Compatibility check: Virtual Machine Interface (V30); database.Manager was removed in Cortina 15. Corresponding support in the virtual machine interface has also been removed. If users are running a custom virtual machine, they must update it to V30 to be compatible with AvalancheGo V1.10.15.
