It's out now, in the regular build thread near the top of this board. Look for a thread titled something like this: JRiver Media Center 23.0.60 -- Available Here

-----------------
The new 64 bit version is 5 to 15% faster than the 32 bit "standard" version, and it can address more memory. Features are identical.
Please post any questions here.
A 64 bit version of MC requires a 64 bit version of Windows. Check under Control Panel > System or About. Most installations of Windows have been 64 bit for a few years. There is no harm in trying if you're uncertain. A 32 bit OS will tell you it can't install.
The first couple of builds didn't pick up the settings or license from the 32 bit version. These should be working now.
Back up from the 32 bit version, uninstall it, then install the 64 bit version.
Update channels should be working, so once you install the 64 bit version, you will receive the updates for it automatically.
If you use plug-ins, you will need to use 64 bit plug-ins with the 64 bit version.
