The latest stable release of Serf is 1.3.10.
It is essential that you verify the integrity of the downloaded files using the PGP signatures and/or file checksums. Please read Verifying Apache Software Foundation Releases for more information on why you should verify our releases.
The PGP signatures can be verified using PGP or GPG. First download the KEYS as well as the asc signature file for the particular distribution. Make sure you get these files from the main distribution directory, rather than from a mirror. Then verify the signatures as follows:
% gpg --import KEYS % gpg --verify serf-1.3.10.tar.bz2.asc
Alternatively, you can verify at least the SHA-512 checksum on the files. A unix program called sha512sum is included in many unix distributions. It is also available as part of GNU Textutils.
For those who would like to participate in Serf development, you may checkout Serf from the Apache Subversion repository:
% svn checkout https://svn.apache.org/repos/asf/serf/trunk serf-trunk
All Serf releases are available for download from the Apache distribution archive.
