Important changes in Reliance 4.2.1



Changes in language localization and the installation program

Previous versions of Reliance 4 had standalone installation programs for the Czech and English versions. The language of the development environment and some other programs could not be changed without re-installing Reliance 4. Beginning with the version 4.2.1, the installation program is common to both language versions. The desired language can be chosen at the beginning of the setup process. The language can later be switched right from the program if needed. Language settings are stored in configuration files.
