+
+* sub-emitter particles may not render correctly in certain scenarios ([8276684](https://github.com/mob-sakai/ParticleEffectForUGUI/commit/8276684c3b1646f0490ed64557547ba15281664a)), closes [#348](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/348)
+* sub-emitter's `inherit velocity` module doubles at runtime ([67de3d1](https://github.com/mob-sakai/ParticleEffectForUGUI/commit/67de3d1bd3e16dc9b564625cb990c53d75769506)), closes [#349](https://github.com/mob-sakai/ParticleEffectForUGUI/issues/349)
