Welcome to CJK version 4.8.4 (18-Apr-2015), a LaTeX 2e macro package that enables the use of CJK scripts (Chinese/Japanese/Korean) in various encodings, written by Werner Lemberg.
A mailing list exists at firstname.lastname@example.org; to subscribe, send a mail with the subject subscribe to email@example.com. A web interface can be found here.
If you are interested in the process of development you may observe the CJK git repository to see the code commitments, and which also provides snapshots.
The package comes in two parts:
cjk-4.8.4.tar.gz The source files. cjk-4.8.4-doc.tar.gz Preformatted documentation files: DVI, PDF, output from cjk-enc.el, etc.
Note that on CTAN and its mirrors, the source archive is unpacked; you must thus get all files and subdirectories from language/chinese/CJK/.
An old article about the CJK package can be found in TUGBoat, volume 18, issue 3.
Recent changes to the CJK package can be found here.
