Notice for future releases
Please note that through Dataset version 9.3.1 the encoding of the Access database and SQL scripts has been CP1252. With effect from the next release, v9.4, anticipated to be made at the end of May 2018, the encoding of these products will be brought in line with that of the online registry and be in UTF-8.
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.

Version 9.3.1 includes the revisions made only in the on-line registry in version 9.3.1 and replaces version 9.3 of 2018-04-20.
