+## Version 23: portable model switches (IDE beta.45)
+
+Cross-provider requests replace encrypted reasoning and every typed encrypted
+peer-message part with a short visible omission note. Ciphertext is never
+interpreted, guessed from its alphabet, or forwarded to another provider. Visible
+messages, peer text, tool calls/results and their order remain intact. Projection
+is idempotent and changes only the outgoing copy. Returning to a subscription
+model retains its original encrypted execution state, including large histories.
+Actual conversation compaction is still rendered through its issuing endpoint;
+unreadable conversation summaries retain the existing explicit error.
+
+Other external-provider switches reuse the same transcript, with destination
+context preparation only when necessary. This follows the Hermes runtime model
+switch contract: `agent/agent_runtime_helpers.py::switch_model` updates the client,
+provider, cache policy and compressor without resetting conversation history;
+`website/docs/user-guide/configuring-models.md` documents in-session `/model`.
+Native voice routing is unchanged.
