0.0.2

Highlights

• Publishes the Goodnotes Swift wrapper at a stable 0.0.2 tag, replacing the need to pin the wrapper commit directly.
• Updates the vendored cpp-httplib header from 0.30.1 to 0.51.0. This includes upstream request/response parsing, redirect, proxy/TLS, chunked-body, header, and cookie security hardening accumulated through the intermediate releases.
• Aligns the CMake dependency pins with maintained releases:
  • cpp-httplib 0.11.3 → 0.51.0
  • JSON for Modern C++ 3.11.2 → 3.12.0 (the SwiftPM-vendored header was already 3.12.0)
  • GoogleTest 1.12.0 → 1.17.0
  • libmaxminddb 1.7.1 → 1.13.3
• Hardens concurrent ruleset polling, evaluation overrides, event flushing, singleton initialization/shutdown, and retained Layer exposure callbacks.
• Adds Swift wrapper tests, deterministic local C++ HTTP fixtures, concurrent lifecycle/polling tests, and standalone Linux CI for both SwiftPM and CMake.

Migration notes

• The minimum CMake version is now 3.16, matching GoogleTest 1.17.0. The library and tests continue to require C++17.
• cpp-httplib 0.31.0 introduced a default 100 MB payload limit, 0.43.0 removed previously deprecated APIs, and 0.44.0 stopped percent-decoding header values. The Statsig wrapper uses the still-supported typed Client and Post(..., Headers, ...) APIs and does not rely on the affected deprecated APIs or decoded-header behavior, so no wrapper source migration was required.
• JSON 3.11.3 and 3.12.0 are documented as backward compatible; no source migration was required.
• The libmaxminddb APIs used here (MMDB_open, MMDB_lookup_string, MMDB_get_value, and MMDB_close) remain compatible.
• GoogleTest is test-only. Its C++17 and CMake requirements are reflected in this release.

Dependency audit

• cpp-httplib 0.30.1…0.51.0
• JSON for Modern C++ 3.11.3 and 3.12.0
• GoogleTest 1.12.0…1.17.0
• libmaxminddb 1.7.1…1.13.3

Validation

• GitHub Actions on Ubuntu: SwiftPM tests passed 2/2; CMake passed 12/12 runnable tests.
• macOS with Xcode 26.5 / Swift 6.3.2: SwiftPM tests passed 2/2; CMake passed 12/12 runnable tests.
• Full C++ ThreadSanitizer suite: 12/12 runnable tests passed with no sanitizer findings.
• Three legacy tests requiring a real test_api_key are skipped when that credential is unavailable.
• Vendored upstream artifact SHA-256:
  • cpp-httplib header: dfbaccb76432ed6d56ddd9983fd9d262b61ba6ba0958f6b00db35c802607bd35

Direct users of statsig::Server should continue to serialize the lifetime of an explicitly constructed Server instance against calls made on that same instance. The global C++ API and Swift wrapper lifecycle are serialized by this release.
