Release Notes for MapE Library Professional

This document contains important information about MapE Library Professional. The release notes cover following issues:

API changes
Database format changes
Migration issue

API changes and migration issue

The MapE Library Professional no longer maintains the object list. We removed the object list to allow MapE handle huge databases. API changes concern CMapLayer class. Please refer to MapE Library documentation for more details.

Database format changes

MapE Library database format (mpl) has been changed to achieve the best performance. MapE Library Professional can read old mpl database and automatically converts it to new format. Please be patient when MapE Library Professional first time reads your old databases. Please note that the MapE Library Standard cannot read MapE Library Professional databases.

Migration issue

These notes concern only MapE Library Professional desktop applications.
