# v0.100.0..v0.101.0: Problems with the combination of zero bone weights and root bones

## API
* [[\#1720](https://github.com/vrm-c/UniVRM/pull/1720)] runtime に BlendShapeProxy.m_merger を再初期化する
* [[\#1719](https://github.com/vrm-c/UniVRM/pull/1719)] vrm の gltf Animation の読み書き仕様

## Importer
* [[\#1675](https://github.com/vrm-c/UniVRM/issues/1675)] SkinnedMeshRenderer.rootBone の boneWeight==0 の頂点を動かす機能を打ち消す
  * [[\#1708](https://github.com/vrm-c/UniVRM/pull/1708)] [1.0] import 時に SkinnedMeshRenderer に対する boneWeight 付与する機能
  * [[\#1705](https://github.com/vrm-c/UniVRM/pull/1705)] [BlendShape] Import 時に BoneWeight が0のMeshにBoneWeightを付与する

## 1.0
* [[\#1713](https://github.com/vrm-c/UniVRM/pull/1713)] [1.0] 親指のボーン名を metacarpal, proximal, distal に変更
* [[\#1706](https://github.com/vrm-c/UniVRM/pull/1706)] [1.0] Awake で初期化するのが早すぎて Runtime ロードで動作しない
* [[\#1715](https://github.com/vrm-c/UniVRM/pull/1715)] Other than position is nullable
