12.1 Release Notes

Red Hat Developer Toolset is a Software Collection from the Red Hat Software Collections offering. It is designed for developers working on the Red Hat Enterprise Linux platform. Using a framework called Software Collections, an additional set of tools is installed into the /opt/ directory, as recommended by the UNIX Filesystem Hierarchy Standard. These tools are enabled by the user on demand using the supplied scl utility. Red Hat Developer Toolset 12.1 provides current versions of the GNU Compiler Collection, GNU Debugger, and other development, debugging, and performance monitoring tools. These do not replace the Red Hat Enterprise Linux system versions of these tools, nor will they be used in preference to those system versions unless explicitly invoked using the scl utility.

These Release Notes contain important information available at the time of release of Red Hat Developer Toolset 12.1. Known problems, resources, and other issues are discussed here. Read this document before beginning to use Red Hat Developer Toolset 12.1.
