- Minor change versioning. The last number in version now mean the number of commits since last release/tag.
- Provide ChangeLog file.
- Fix for using libmdbx as C-only sub-project with CMake.
- Fix `mdbx_env_set_geometry()` for case it called from opened environment outside of write transaction.
- Add support for huge transactions and `MDBX_HUGE_TRANSACTIONS` build-option (default `OFF`).
- Refine LTO (link time optimization) for clang.
- Force enabling exceptions handling for MSVC (`/EHsc` option).
v0.8.0 2020-06-05:
- Support for Android/Bionic.
