1.8.0

• PACKAGE_VERSION is now a private compile definition when building
  with CMake. Pull request by bsergean. GitHub #308.
• PACKAGE_VERSION is no longer defined in maxminddb.h on
  Windows.
• The feature test macro _POSIX_C_SOURCE is no longer set by
  maxminddb.h. As discussed in GitHub #318, this should be set by
  applications rather than by libraries.
• assert() is no longer used outside test code.
• The deprecated Visual Studio 12 project files in the projects/
  directory have been removed. CMake should be used when building on
  Windows.

1.7.1

• The external symbols test now only runs on Linux. It assumes a Linux
  environment. Reported by Carlo Cabrera. GitHub #304.

1.7.0

• FD_CLOEXEC is now set on platforms that do not support O_CLOEXEC.
  Reported by rittneje. GitHub #273.
• When building with Visual Studio, you may now build a static runtime with
  CMake by setting MSVC_STATIC_RUNTIME to ON. Pull request by Rafael
  Santiago. GitHub #269.
• The CMake build now works on iOS. Pull request by SpaceIm. GitHub #271.
• The CMake build now uses the correct library directory on Linux systems
  using alternate directory structures. Pull request by Satadru Pramanik.
  GitHub #284.
• File size check now correctly compares the size to SSIZE_MAX. Reported
  by marakew. GitHub #301.

1.6.0

• This release includes several improvements to the CMake build. In
  particular:
  • C99 support is now properly enabled, fixing builds on older gcc
    versions. Pull request by Jan Včelák. GitHub #257.
  • CMAKE_SHARED_LIBRARY_PREFIX and CMAKE_STATIC_LIBRARY_PREFIX are
    no longer explicitly set and now use the default values for the platform.
    Pull request by Jan Včelák. GitHub #258.
  • target_include_directories now works as expected. Pull request by Jan
    Včelák. GitHub #259.
  • DLLs are now installed on Windows when libmaxminddb is built as a
    shared library. Pull request by Jan Včelák. GitHub #261.
  • When built as a dynamic library on Windows, all symbols are now exported.
    Pull request by Jan Včelák. GitHub #262.

1.5.2

• With libmaxminddb on Windows and mmdblookup generally, there were
  instances where the return value of calloc was not checked, which could
  lead to issues in low memory situations or when resource limits had been
  set. Reported by cve-reporting. GitHub #252.

1.5.1

• The formatting of the manpages has been improved and the script that
  generates them now supports lowdown in addition to pandoc. Pull request
  by Faidon Liambotis. GitHub #248.

1.5.0

• A CMake build script has been added for Windows builds. The Visual
  Studio project files in projects are now considered deprecated and will
  be removed in a future release.

1.4.3

• On Windows, always call CreateFileW instead of CreateFile.
  CreateFile could be mapped to CreateFileA and not work as expected.
  Pull request by Sandu Liviu Catalin. GitHub #228.
• Fixed use of uninitialized memory in dump_entry_data_list() that could
  cause a heap buffer flow in mmdblookup. As part of this fix, most uses
  of malloc were replaced with calloc. Reported by azhou. GitHub #236.

1.4.2

• The 1.4.0 release introduced a change that increased the size of MMDB_s,
  unintentionally causing an ABI break. This release reverts the relevant
  commit.

1.4.1 - DO NOT USE

DO NOT USE. UNINTENDED ABI BREAK.

• The man page links for function calls were not generated correctly in
  1.4.0. This has been corrected.
