As ERC has become more of a mature product within the past few years, we have decided to discontinue having a separate development effort for it, in favor of having it maintained within the Emacs source tree. Patches may be submitted to emacs-devel AT gnu.org.
I am pleased to announce the release[1] of ERC 5.2. The release is available from your favorite GNU FTP mirror. The URLs for this release on the primary GNU FTP mirror are as follows.
Tarball :: http://ftp.gnu.org/gnu/erc/erc-5.2.tar.gz
