- BDL provider can be enabled vor NVS in the menuconfig option NVS_BDL_STACK - Hierarchy of Partition class tree was adjusted and all operations were documented - Class Partition is now derived from intrusive_list_node and ExceptionlessAllocable - Class NVSPartition implements only the dual support for esp_partition and BDL - Class NVSEncryptedPartition implements only encryption related extensions
