| Backward compatibility break: | ||||
|  | ||||
|  - The `MDBX_AVOID_CRT` build option was renamed to `MDBX_WITHOUT_MSVC_CRT`. | ||||
|    This option is only relevant when building for Windows. | ||||
|  - The `mdbx_env_stat()` always, and `mdbx_env_stat_ex()` when called with the zeroed transaction parameter, now internally start temporary read transaction and thus may returns `MDBX_BAD_RSLOT` error. | ||||

|    So, just never use deprecated `mdbx_env_stat()' and call `mdbx_env_stat_ex()` with transaction parameter. | ||||
|  - The build option `MDBX_CONFIG_MANUAL_TLS_CALLBACK` was removed and now just a non-zero value of | ||||
|    the `MDBX_MANUAL_MODULE_HANDLER` macro indicates the requirement to manually call `mdbx_module_handler()` | ||||

|  - Switched to using Heap-functions instead of LocalAlloc/LocalFree on Windows. | ||||
