+## What's new in 0.14.0
+
+- **The persona layer as a library crate, for std and `no_std` hosts.** `probbit-persona` holds the document layer and the
+  strand writer (`Live`, the line writers, `Replay`, `verify*`, no file I/O), with the features `std` (default) and `nostd`
+  (`no_std` + `alloc`, checked on `xtensa-esp32s3-none-elf`); the CLI uses it unchanged and every CLI output of the move is
+  byte for byte as 0.13.0. Setup, the turn and resume return boxed values, so one event's stack high-water on the host proxy
+  fell from 31,824 to 13,808 bytes (setup: 39,056 to 12,112); a strand resumes from its last checkpoint or from a state
+  record behind it, and seals into segments ([docs/embedding.md](docs/embedding.md) "Stack budget", "Sizing a strand on
+  flash", "Resume on a body").
+- **The expectation cache.** The expectation keeps an exact cache and solves the event's own program once; every stance,
+  strand line and digest is the same with the cache on or off (a life of one repeated event, host proxy: `expect` 52 % → 37 %
+  of the turn, 95 % of its programs from the cache; [docs/embedding.md](docs/embedding.md) "The expectation's cache" and
+  "The expectation's members").
+- **The self layer, off by default** ([RFC 0013](docs/rfcs/0013-self-report.md), [0014](docs/rfcs/0014-integrity.md),
+  [0015](docs/rfcs/0015-consolidation.md), [0016](docs/rfcs/0016-curiosity.md)): `probbit reflect` and reflection lines (a
+  canonical account of a window of events from the lines alone, no solve), integrity (per trait the drift from the declared
+  self against RFC 0004's allowance; the monitor's dial and the Mirror tab), the rest pass (`live control STRAND rest`, one
+  `consolidation` line) and curiosity (a drive fed by the measured surprise, with an optional stir). Each part is opt-in and a
+  deterministic function of the logged lines that `probbit live verify` recomputes. A declared, replayable self; it does not
+  feel. A persona that declares none of its keys gets every document byte for byte as before (P0: 653 outputs, 0 differ).
+- **An optional tier, off by default: a simulated amplitude register, exact, on a CPU** (`engine: {tier: amplitude}` the
+  opt-in; [RFC 0011](docs/rfc/0011-amplitude-register.md), [the demo](examples/persona/demo/)): at one event of the demo
+  tutor the thermal odds of the top two humour levels sit 0.007412 apart and the register's long sweep separates them by
+  0.494808; a register strand recorded on a 0.14.0-dev build before the tier's last round may not verify on 0.14.0.
+- Engine gate: strands with the new line kinds or keys read as unsupported (exit 5) on 0.13.x. The release has 15 assets:
+  six archives, `probbit-Monitor-v0.14.0-macos.zip`, a `.sha256` for each, and `probbit.1`.
