This is bugfix release of stable libmdbx branch, on the day of the 100th
anniversary of the birth of the outstanding Soviet and Russian scientist
and engineer Vladimir Fedorovich Utkin.
It is reasonable to backport this patch to all applicable releases/branches of Buildroot.
The most significant fixes of v0.12.8:
- Fixed regression of mdbx_put(MDBX_MULTIPLE) during batch/bulk
insertion of multi-values (aka "dupsort").
- Implemented overwriting in mdbx_put(MDBX_CURRENT) of all current
multi-key values in the absence of the flag MDBX_NOOVERWRITE.
- Added the ability to use mdbx_cursor_get(MDBX_GET_MULTIPLE) without
first setting the cursor, combining the batch data getting operation
with positioning the cursor.
- Micro-optimization and refactoring cursor_put_nochecklen().
- Clarifying the wording in the API description, including explanation
about SIGSEGV and not allowing direct data changes.
