Leading enterprise-grade Open Source version control system introduces numerous enhancements
and features that simplify administration and further automate functionality

18 June 2013 --Forest Hill, MD-- The Apache Software Foundation (ASF), the all-volunteer developers,
stewards, and incubators of nearly 150 Open Source projects and initiatives, today announced
Apache Subversion 1.8.0.

Considered the most popular and widely-used Open Source version control system [1], Subversion
was established in 2000 and submitted to the Apache Incubator in 2009. Since graduating as
an Apache Top-Level Project in 2010, the Subversion community has continued to focus on meeting
the diverse needs of both Open Source developers and worldwide enterprise environments with
large data sets and complex branch topologies.

"Version control is a fundamental element of best practices for software development," said
Apache Subversion Vice President Greg Stein. "Subversion has experienced tremendous success,
becoming the go-to solution for stable, reliable version control for countless development
teams.  Version 1.8.0 reinforces our commitment to delivering enterprise-ready functionality
with an entry-level learning curve."

"Apache Subversion helps us build tailor-made software for enterprises all around the world,"
said Damir Deželjin, IT Solutions Architect at ComTrade. "Using a stable, secure, mature,
maintainable source control system is of the utmost importance in building upon our 20-year
history of successfully delivering projects of all different sizes. We are happy to confirm
that our choice to adopt Subversion as a core source control system was the right decision."

Under the Hood
Apache Subversion 1.8.0 builds and expands upon the feature provisions of earlier releases
to address many of the most commonly requested enhancements.

Since their introduction in prior releases, Subversion’s merge tracking and tree conflict
detection features have been critical to its ability to serve projects where branching and
merging happens often. The 1.8.0 version improves these features, further automating the client-side
merge functionality and improving both tree conflict detection during merge operations and
tree conflict resolution during update operations. Additionally, the Subversion client now
tracks moves of working copy items as first-class operations, which brings immediate benefit
to users today and is a key step toward more thorough system-wide support for moved and renamed
objects in a future release.

The release brings improvements which benefit administrators as well.  One of the most common
requests made by Subversion administrators has been for a unified mechanism by which to govern
client-side configuration settings such as ignore patterns and automatic property definitions.
 Subversion 1.8.0 delivers a clean answer to this request via newly introduced support for
inheritable configuration-related properties which are stored in the repository itself.

"ADVA Optical Networking's 800+ software engineers collaborate from 10 locations worldwide
to deliver innovative networking solutions, and Subversion is an important part of those collaboration
activities," said Sridhar Machina, Manager of R&D Source Control. "We are very excited
about the 1.8.0 release, and are specifically interested in the administration simplifications
promised by the new repository-dictated configuration feature."

Subversion developers also targeted the flat-file repository storage backend (known as "FSFS")
for a series of improvements in this release which include revision property caching, revision
property file packing, and deltified storage of properties and directory entries lists.  While
most of these enhancements aren’t user-visible, administrators will appreciate the increased
performance and reduced disk usage they deliver.

"WordPress.org hosts tens of thousands of Subversion repositories that are used and abused
in every way imaginable," explained WordPress founder Matt Mullenweg. "I'm very much looking
forward to seeing how the new storage efficiency saves us space so we can serve our community

In addition to new functionality, Subversion 1.8.0 completes the migration away from a dependency
on the Neon HTTP library.  The client will now accomplish its HTTP-based network communications
solely with the newer Serf library, which provides pipelined and cacheable access to the server,
thereby improving performance.

Also, in light of the enhancements made for the newer FSFS repository storage backend and
those already planned for future releases, the project has officially deprecated the original
BerkeleyDB-based storage backend. The BerkeleyDB storage option will continue to be available
and supported, but development efforts going forward will be focused on the FSFS backend.

"We are serious about addressing some long-term and nontrivial feature requests, and in order
to do that we need to focus our efforts on a single storage backend," explained C. Michael
Pilato, member of the Apache Subversion Project Management Committee. "Moving forward with
the backend that is easiest to use and maintain and which is already nearly universally deployed
makes sense."

Commitment to Progress
The Subversion 1.8.0 release is the culmination of many months of coding effort, but the design
and development effort which resulted in this new version shows no sign of slowing in its
wake. The release closely follows a recently held hackathon-style gathering of Subversion
developers in Berlin, where participants celebrated the accomplishment and addressed future
enhancements and releases. The driving force behind those discussions was the same as when
the project was first founded: delivering reliable version control features that address tangible
user requirements.

"Apache Subversion has continued to stay relevant and incredibly useful due to our commitment
to working with our large community of users, understanding their requirements, and enhancing
Subversion to meet those needs. That connection to our community is how we keep our broad
base of Subversion users happy," added Stein.

Availability and Oversight
As with all Apache products, Apache Subversion software is released under the Apache License
v2.0, and is overseen by a self-selected team of active contributors to the project. A Project
Management Committee (PMC) guides the Project's day-to-day operations, including community
development and product releases. Apache Subversion release notes, source code, documentation,
and related resources are available at http://subversion.apache.org/.
