i. IOGP is planning for the EPSG Dataset to adopt the recent changes made to the ISO 19111 data model to describe dynamic coordinate reference systems and datum ensembles. We anticipate that the updated model will be introduced in 2019. Details of proposed changes will be circulated later this year.
ii. Through Dataset version 9.3 the encoding of the Access database and SQL scripts has been CP1252. With effect from this v9.4 release, the encoding of these products has been brought in line with that of the online registry and is in UTF-8. The zip files for previous versions of the Dataset in CP1252 encoding have file name like "epsg-v9_3sql-MySQL.zip", "epsg-v9_3sql-Oracle.zip" and "epsg-v9_3sql-PostgreSQL.zip" whereas the zip files for this and future versions of the Dataset in UTF-8 encoding have file name like "EPSG-MySQL-export-9.4.zip", "EPSG-ORACLE_SQL-export-9.4.zip" and "EPSG-PSQL-export-9.4.zip"; the naming of the script files within the zip files is unchanged.
