The Apache Software Foundation Announces Apache® Subversion® 1.15, Featuring “Pristines On Demand” for Large-File and Large-Repository Workflows

New feature cuts local working-copy storage requirements by up to 50%, extending Subversion’s long-standing strength in version control for huge repositories and huge files

Wilmington, DE, Oct. 14, 2026 (GLOBE NEWSWIRE) — The Apache Software Foundation (ASF), the global home of open source software the world relies on, today announced the release of Apache Subversion 1.15, the latest version of the widely-used, centralized version control system. The release’s headline feature, Pristines On Demand, gives users the option to reduce local storage requirements by up to 50% — a capability designed for organizations that rely on Subversion to manage terabytes of large files.

Apache Subversion helps individuals and teams manage, collaborate on, and track changes to files as a project evolves. It provides a single source of truth, an accurate record of every change, and access to the latest (or any prior) version of a file. Subversion’s centralized architecture, optional file-locking, granular access controls, and support for partial and sparse checkouts have made it a longstanding choice for teams working with large or sensitive files, while its comparatively simple mental model keeps it approachable for non-technical users.

That combination has drawn Subversion users well beyond software development, into fields such as industrial automation, CAD design, automotive manufacturing, document management, video game asset management, and state health care administration — many of whom manage repositories that run into the terabytes, with individual files in the gigabytes.

Pristines On Demand: Trading Bandwidth for Storage

Subversion working copies traditionally keep a local cached copy of each original file called a “pristine.” Pristines On Demand lets users forgo that local cache and instead fetch them from the repository server only when needed. The tradeoff is a potential increase in network communication in exchange for a smaller footprint on the local device — a tradeoff that benefits any workflow where server bandwidth is more abundant than local storage, and one first requested by the Subversion community in a 2001 issue-tracker ticket that gained renewed priority as more corporate users sought smaller checkout sizes.

“Subversion has long been one of the best open source solutions for version control of large binary objects and data,” said Karl Fogel, member of the Apache Subversion Project Management Committee (PMC). “The new Pristines On Demand feature makes it even more suitable for this, reducing client-side storage usage by half while still satisfying Subversion’s high standards for inter-version compatibility.”

Apache Subversion’s maintainers describe the 1.15 release as part of a broader commitment to the specific strengths that distinguish Subversion from distributed version control systems (DVCS); namely, its fit for centralized management of huge repositories and huge files, and its accessibility to non-technical users.

“Version control is not just for software engineers,” said Nathan Hartman, Vice President of the Apache Subversion PMC. “Subversion’s user base comes from a wide variety of fields with varying technical abilities. One of Subversion’s strengths is the ability to scale from small repositories to huge ones. We have heard from users who have repositories terabytes in size, containing files gigabytes in size.”

Apache Subversion 1.15 is available now for download. Full details are available in the 1.15 release notes.
