📦 What's inside

• A new home for Proxy
• Proxy has moved from [microsoft/proxy](https://github.com/microsoft/proxy) to [ngcpp/proxy](https://github.com/ngcpp/proxy), with a new documentation home at [ngcpp.github.io/proxy](https://ngcpp.github.io/proxy/).
• Governance and support documents were updated for ngcpp stewardship.
• Copyright notices now preserve Microsoft's original ownership for 2022-2026 and add ngcpp for ongoing development starting in 2026.
• Meson joins CMake
• Proxy now ships Meson build files alongside CMake, making it much easier to consume the library in Meson-based projects.
• The Meson integration covers header installation, tests, benchmarks, and extracting examples from the docs, with optional `pkg-config` metadata when available.
• Existing CMake flows continue to work, so current integrations do not need to change.

📦 Upgrading

• Most users can update to 4.0.2 and rebuild.
• Repository and docs URLs
• Update repository links from `github.com/microsoft/proxy` to `github.com/ngcpp/proxy`.
• Update documentation links from `microsoft.github.io/proxy` to `ngcpp.github.io/proxy`.
• Build systems
• Public namespaces and current CMake target names remain unchanged in 4.0.2.
• Existing CMake integrations continue to work as before.
• Meson is now supported for header installation, tests, benchmarks, and docs examples. Meson consumers can integrate Proxy through `dependency('msft_proxy4')`, with `pkg-config` metadata generated when that tooling is available.

📦 Acknowledgments

• Thank you to everyone who helped move Proxy into its next chapter. A special thanks to @mochaaP for landing Meson support and expanding the project's build-system reach.

📋 What's Changed

• Improve constraints for `facade` by @mingxwa in [microsoft/proxy#359](https://github.com/microsoft/proxy/pull/359) - tightened `ProBasicFacade` and builder validation for layout and constraint settings.
• Remove support for standard trivial relocation by @mingxwa in [microsoft/proxy#365](https://github.com/microsoft/proxy/pull/365) - removed an incomplete, untested relocation path.
• Avoid false positive for `ptr_traits` by @mingxwa in [microsoft/proxy#367](https://github.com/microsoft/proxy/pull/367) - made pointer-trait detection stricter and improved `proxiable` edge cases.
• Fix overload resolution in `PRO_DEF_FREE_AS_MEM_DISPATCH` by @mingxwa in [microsoft/proxy#372](https://github.com/microsoft/proxy/pull/372) - fixed a regression and added broader dispatch coverage.
• Simplify the implementation of `strong_compact_ptr` by @mingxwa in [microsoft/proxy#368](https://github.com/microsoft/proxy/pull/368) - reduced internal complexity without changing intended behavior.
• Fix wording for proxy indirection by @mingxwa in [microsoft/proxy#369](https://github.com/microsoft/proxy/pull/369) - aligned the docs with the current mandatory indirection model.
• Revise benchmarks by @mingxwa in [microsoft/proxy#373](https://github.com/microsoft/proxy/pull/373) - regrouped metrics, switched facades to `slim`, and added relocation measurements.
• Update toolchain by @mingxwa in [microsoft/proxy#378](https://github.com/microsoft/proxy/pull/378) - refreshed compiler coverage and dependency versions, including `fmt` 12.x compatibility work.
