"3.x.x" -> The current stable release branch of ESOS; you'll see versions like "3.0.0", "3.0.1", etc. in this directory. Only minor new features and bug fixes. The package file names all reflect a Git tag name (version).
"master" -> The development branch of ESOS... bleeding edge, new features, latest and greatest. Should be considered unstable; we'll create branch(es) from here that become supported stable branches of the software. Package files in this directory will have the following naming convention: "esos-BRANCH_HASH_OPTS.zip" The value BRANCH will be the name of the branch, "master" in this case; the HASH value is the Git commit hash (short); and OPTS is the letter designation of any build options set (see below).
"2.x.x" -> This is a deprecated branch of ESOS; no bug fixes will be issued for this branch, please consider upgrading to the current release branch of ESOS.
"1.x.x" -> This is a deprecated branch of ESOS; no bug fixes will be issued for this branch, please consider upgrading to the current release branch of ESOS.
"0.1.x" -> This is a deprecated branch of ESOS; no bug fixes will be issued for this branch, please consider upgrading to the current release branch of ESOS.
