Download clibs.8xg and send to your calculator using TI Connect CE.
Important
If you're using ChromeOS, the TI-Connect CE app from TI will not transfer everything in this group file!
To work-around this, you will need to download clibs_separately_in_zip.zip, extract that zip archive, then send each file in it to your calculator.
Note
If you have an error about missing GRAPHC, you can download the older GRAPHC library here.
If you somehow need the "nightly" version of the libraries (bleeding edge not yet officially released) due to a version error, they're available here
