===================================
Library
-------
+ - Fixed an issue with collective metadata reads being permanently disabled
+ after a dataset chunk lookup operation. This would usually cause a
+ mismatched MPI_Bcast and MPI_ERR_TRUNCATE issue in the library for
+ simple cases of H5Dcreate() -> H5Dwrite() -> H5Dcreate().

+ (JTH - 2021/11/08, HDFFV-11090)

- Fixed cross platform incompatibility of references within variable length
