Released: May 28, 2026

Updates in 2026.5.5

Features

• Context hibernation policy (HibernationMode, IKVCache, Configuration, MultiTurnConversation, PdfChat, RagChat, AgentExecutor): new HibernationMode enum (Auto, None, Forced), per-conversation IKVCache.HibernationMode get/set property on every multi-turn conversation type, and a process-wide Configuration.DefaultContextHibernationMode that seeds the value on every new conversation. In Forced mode the runtime hibernates the KV-cache to disk in the background at the end of every turn; the caller returns immediately and the next turn rehydrates transparently. None keeps the context resident. Auto is the default, reserved for runtime-driven heuristics, and currently behaves like None.
