1.18.0 release

Added

• Signed binaries for macOS and Linux are now available on the GitHub release.
  • Linux binaries including nocrypto in the name have no dependency on OpenSSL. Drivers using the nocrypto variant are expected to set crypto callbacks (e.g. call mongocrypt_setopt_crypto_hooks) to do operations requiring crypto to avoid an error.
  • Drivers that package libmongocrypt binaries are encouraged to migrate release scripts to use these binaries.
    • No reduction in platform support is expected. glibc dependencies were checked against existing builds on RHEL 6.2 and Ubuntu 16.04.
• Support referencing keys by keyAltName in encryptedFieldsMap.

Changed

• Final release packages in the PPA are now available by specifying release in the repository configuration in place of the major/minor version (e.g., 1.17). Details in README.md.
• Bump downloaded libbson version from 2.1.0 to 2.3.0.

Deprecated

• RHEL 6.2 builds are deprecated and may be removed in the future. The linux-x86_64-glibc_2_7-nocrypto release build may be used instead and has equivalent glibc requirements.
• Use of s3.amazonaws.com URLs to download libmongocrypt binaries. Please see binaries attached to the GitHub release.

Removed

• The configure-time CMake parameter ENABLE_WINDOWS_STATIC_RUNTIME has been removed. Users that need the static MSVCRT library should instead set the CMAKE_MSVC_RUNTIME_LIBRARY built-in CMake parameter when configuring libmongocrypt.
• Packages for Debian 9 and Debian 10.
