HOOPS 3DF 30.60
Overview
3DF 30.60-LTS is a security‑hardening release within the 30.x Long Term Support branch.
What’s New in 30.60-LTS
- The headline changes are an upgrade of libPNG to v1.6.56 and zlib to v1.3.2 to resolve partner‑blocking CVEs — driven primarily OEM security scanning requirements. The release also eliminates ImageMagick’s bundled PNG codepath in favor of the standalone, up‑to‑date libPNG, reducing the overall CVE surface area of the SDK.
- Beyond security, this release addresses several high‑priority partner defects in rendering, C# API stability, and Remote Desktop reconnection scenarios.
- LTS note: 3DF 30.x is the current Long Term Support branch (Year 2 — limited feature development, defect resolution unlikely to cause discontinuity). For the latest features, see the 3DF 31.x stream.
Technology Update
Platform Changes
- Platform Deprecation Announcement: Support for macOS on Intel architecture will be discontinued starting with 3DF 32.00 and 30.80-LTS due to the end of support in macOS 27.
