The KEYS link links to the code signing keys used to sign the product. The PGP link downloads the OpenPGP compatible signature from our main site. The MD5 link downloads the checksum from the main site.
There are two different binary releases, oldkey and newkey. Both contain assemblies built for most supported platforms and have been built from the same code base, they only differ in the strong name key used to sign the assemblies.
See the FAQ for background. We recommend you use the assemblies signed with the "new" key whenever possible.
Release 1.2.11 and all more recent releases are available from the Apache Software Foundation's distribution archive.
The 1.2.10 and 1.2.9 releases have been created while log4net was still undergoing incubation and those releases are available from the distribution archive for the Incubator project.
Previous releases of log4net are available from the SourceForge Project Site.
It is essential that you verify the integrity of the downloaded files using the PGP signature or MD5 checksums. The checksums are not as strong indicators as the PGP signature.
