 > 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.
