Privacy fix: bitHumanKit withdrawn (returns in 2.22.4); Expression2/Essence2 unchanged

v2.22.1

Swift package 2.22.1: E2UEngine 1.0.6 (Essence 2 full-body idle clip on Apple, sha-pinned, fail closed) and a note: check meteringRefusal after warmUp().

v2.22.0

bitHuman Swift package 2.22.0 (every product ships as a prebuilt binary)

v2.21.7

bitHuman Swift package 2.21.7 (Expression2 v2.20.7; ORT third-party notices)

Swift package 2.21.6: E2UEngine e2u-v1.0.4

v2.21.5

cli-v2.8.11

bithuman CLI 2.8.11: the formula pins cli-v2.8.11's signed, notarized macOS tarball on downloads.bithuman.ai (sha256 0fec9436805f81cd1c8600b3a5c1cd838206fa67427e2ce390ff765a696bda51). The new Essence 2 renders through the Python package (render --mode full|face); avatars whose manifest stores a whole number as a float load with their gestures. Engine pin essence1-v3.1.3-e2.63; billing unchanged.

v2.21.4

Swift package 2.21.4: smoother head motion, Sofia loads, iOS Simulator builds (E2UEngine e2u-v1.0.2)

v2.21.3

Swift package 2.21.3: unified Essence 2 full body 2x faster (E2UEngine e2u-v1.0.1)

v2.21.2

Swift package 2.21.2: no crash when an engine is released off the main thread on iOS

v2.21.1

Swift package 2.21.1: Xcode macOS apps linking Essence2Kit build again (EngineCore enginecore-v1.0.3)

v2.21.0

Swift package 2.21.0: Essence2Kit runs the unified Essence 2 engine (essence-2 / essence-2f)

v2.20.6

Swift package 2.20.6: Expression2 v2.20.6 (a reply streamed in real time starts with a lead instead of stalling at each 1.6 s chunk)

cli-v2.8.10

bithuman CLI 2.8.10: the formula pins cli-v2.8.10's signed, notarized macOS tarball on downloads.bithuman.ai (sha256 2ad5a4fdea6394dc00b9a3f311451c1652731f93b5d6808b5e2e3bb5939a9bd2). Gallery codes render (bithuman render X03BOLT speech.wav); render exits 0 only when the video was written, else 70 NO_OUTPUT_WRITTEN; Essence 2 on x86-64 Linux uses less CPU per frame and about 100 MB less memory (LE_WARP_NODE=0 restores the previous output); the Essence 2 teeth step and Expression 2 offline renders on Linux are faster with byte-identical frames. Engine pin essence1-v3.1.3-e2.61; billing unchanged.

flutter-plugin-v2.6.40

Flutter plugin 2.6.40: the model door's 404 MODEL_ARTIFACT_NOT_READY (a character still training, or its on-device copy still being built) is BithumanModelPreparing ("Preparing this character for your device…"; retry 30 s, 60 s, 120 s, then every 300 s, up to 10% jitter), never a credential failure. Recognised as a 404 from the door whose first "code" in the body's first 300 bytes is MODEL_ARTIFACT_NOT_READY; every other 404, 409 and 5xx keeps its 2.6.39 answer. Additive API: BithumanModelPreparing (a BithumanEntitlementException, refused false, status 404), retryWhileModelPreparing, kModelArtifactNotReady; Android channel code model_preparing. scripts/bootstrap.sh refuses and un-stages a staged library that asks ONNX Runtime for a C API version above the staged runtime's (26), and fails closed on one it cannot read. Engines unchanged: Expression 2 v2.20.4, Essence 2 essence2-v1.15.5, enginecore v1.0.2, libconverse converse-apple-v2.5.2; Android essence2-android 0.9.5, expression2-android 0.6.1. Apple minimums as in 2.6.39.

flutter-plugin-v2.6.39

Flutter plugin 2.6.39: macOS links the static ONNX Runtime 1.26.0 the plugin vendors (no brew onnxruntime at build or run time; no /opt/homebrew library or rpath in the app), and the on-device brain is libconverse converse-apple-v2.5.2 (macOS slice on the ORT 1.26 headers; iOS slices byte-identical to v2.5.1). Expression 2 refuses by name (code unsupported) below iOS 18 / macOS 15, before any CoreML compile. Engines unchanged: Expression 2 v2.20.4, Essence 2 essence2-v1.15.5, enginecore v1.0.2; Android essence2-android 0.9.5, expression2-android 0.6.1. Link floors iOS 16.4, macOS 14.0; Expression 2 needs iOS 18 / macOS 15; Essence 2 and LOCAL mode need iOS / macOS 26. One ONNX Runtime per app on iOS and macOS. MR !216.

flutter-plugin-v2.6.38

Flutter plugin 2.6.38: GitHub independence. The plugin installs from the public tap on GitLab (url https://gitlab.com/bithuman/sdk/homebrew-bithuman.git, path packages/flutter-plugin), and scripts/bootstrap.sh downloads everything from https://downloads.bithuman.ai (no gh, no code host; the private area only with BITHUMAN_DOWNLOADS_TOKEN), against the same sha256 pins as 2.6.37. Engines unchanged: Expression 2 v2.20.4, Essence 2 essence2-v1.15.5, enginecore v1.0.2, libconverse converse-apple-v2.5.1; Android essence2-android 0.9.5, expression2-android 0.6.1. Floors iOS 16.4, macOS 14.0. MR !213.
