v0.9.x (in the development):
- TODO: Native bindings for C++.
- TODO: Packages for AltLinux, Fedora/RHEL, Debian/Ubuntu.

v0.8.1 2020-06-12:
- 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 (defaultOFF
). - 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.
- Support for iOS.

- Fix
MDBX_AVOID_CRT
option and missingntdll.def
. - Fix
mdbx_env_close()
to work correctly called concurrently from several threads. - Fix null-deref in an ASAN-enabled builds while opening environment with error and/or read-only.

- Fix using
ENODATA
for FreeBSD. - Avoid invalidation of DBI-handle(s) when it just closing.

MDBX_UTTERLY_NOSYNC
as result of flags merge. - Add
mdbx_dbi_dupsort_depthmask()
function. - Add
MDBX_CP_FORCE_RESIZEABLE
option. - Add deprecated

option (defaultON
). - Refine
mdbx_dbi_open_ex()
to safe concurrently opening the same handle from difference threads. - Truncate clk-file during environment closing. So zero-length lck file indicates that environment was closed properly.
- Refine
