These are the minimum versions we plan to support throughout the version series
-
Older versions are not actively supported or tested.
It is possible to build zlib-ng outside of these minimums, however support for doing so is limited, and is not guaranteed to work later in the version series.
Community patches are accepted. -
Other compilers are not actively supported or tested.
Community patches are accepted. -
* Configure is still supported in 2.1.x, but at a reduced feature level compared to CMake.
Configure only has basic tests. -
** NMake buildsystems are no longer actively supported and tested.
Community patches are accepted.

These are not all actively tested, and are meant like a guideline
Several macros can be used to detect the version of zlib-ng at compile time. They can be found in zlib-ng.h or zlib.h (depending on whether or not you are compiling for zlib compatibility).
| Macro | Description |
|---|---|
| ZLIBNG_VERNUM | Full 32-bit version of zlib-ng in the format MMNNRRMS: major minor revision status modified. Prior to 2.1.x it was a 16-bit value 0x2060 in the format MNRS. |
| ZLIBNG_VER_MAJOR | Major version |
| ZLIBNG_VER_MINOR | Minor version |
| ZLIBNG_VER_REVISION | Revision |
| ZLIBNG_VER_STATUS | (DEPRECATED) 0=devel, 1-E=beta, F=Release |
| ZLIBNG_VER_STATUSH | 0x0=devel, 0x1-0xE=beta, 0xF=Release |
| ZLIBNG_VER_MODIFIED | non-zero if modified externally from zlib-ng |
