Audacity Forum

I just used Audacity 1.2.6, then installed 1.3 Beta. The installation has not replaced the old version, but was installed in own directory. Why? This takes additional space, etc. I read somewhere that new installation should be installed over the old installation.

That was incorrect. Audacity 1.2 and 1.3 will safely install on the same machine. You may not use both at the same time. Audacity 1.3 Projects will not open in 1.2.
