ARC 15.03 update 10
The Advanced Resource Connector (ARC) middleware is an Open Source software solution to enable distributed computing infrastructures with the emphasis on processing large volumes of data. ARC provides an abstraction layer over computational resources, complete with input and output data movement functionalities. The security model of ARC is identical to that of Grid solutions, relying on delegation of user credentials and the concept of Virtual Organisations. ARC also provides client tools, as well as API in C++, Python and Java.
This is a minor release, introducing new features and addressing bugs discovered since release 15.03u9. The release includes all recent developments up until now excluding only those that would result in backward incompatabilities. For these a major release is expected in the beginning of next year.
Note that from next major release we will not continue support for EL5 and Ubuntu 10.04 LTS. This is a consequence of significant code changes when implementing OpenSSL 1.1.0 in ARC needed for continued support of Fedora, which as of Fedora 25 moves to OpenSSL 1.1.0. In general, support of OpenSSL versions lower than 1.0.0 will be dropped. In addition legacy proxies will not be supported starting with the next major release.

The frontier-squid software package is a patched version of the standard squid http proxy cache software, pre-configured for use by the Frontier distributed database caching system. This installation is recommended for use by Frontier in the LHC CMS & ATLAS projects, and also works well with the CernVM FileSystem. Many people also use it for other applications as well

XRootD software framework is a fully generic suite for fast, low latency and scalable data access, which can serve natively any kind of data, organized as a hierarchical filesystem-like namespace, based on the concept of directory. As a general rule, particular emphasis has been put in the quality of the core software parts.
