 - **[major change]** by starting v0.5.1, built-in alignment is removed from **vec3** and **mat3** types
 - **[major change]** by starting v0.7.3, inline print functions are disabled in release/production mode to eliminate print costs (see options in documentation). Print output also improved. You can disable colors if you need  (see documentation)
- **[major change]** by starting v0.8.3, **cglm** supports alternative clipspace configuations e.g. Left Handed, Zero-to-One (_zo)... `CGLM_FORCE_DEPTH_ZERO_TO_ONE` and `CGLM_FORCE_LEFT_HANDED` is provided to control clipspace.

+#### Note for new comers (Important):
 - `vec4` and `mat4` variables must be aligned. (There will be unaligned versions later)
 - **in** and **[in, out]** parameters must be initialized (please). But **[out]** parameters not, initializing out param is  also redundant
 - All functions are inline if you don't want to use pre-compiled versions with glmc_ prefix, you can ignore build process. Just include headers.
 - if your debugger takes you to cglm headers then make sure you are not trying to copy vec4 to vec3 or alig issues...

+#### Note for experienced developers:
 - Since I'm testing this library in my projects, sometimes bugs occurs; finding that bug[s] and making improvements would be more easy with multiple developer/contributor and their projects or knowledge. Consider to make some tests if you suspect something is wrong and any feedbacks, contributions and bug reports are always welcome.

-#### 📌 Allocations?
+#### Allocations?
 `cglm` doesn't alloc any memory on heap. So it doesn't provide any allocator. You should alloc memory for **out** parameters too if you pass pointer of memory location. Don't forget that **vec4** (also quat/**versor**) and **mat4** must be aligned (16-bytes), because *cglm* uses SIMD instructions to optimize most operations if available.

-#### 📌 Returning vector or matrix... ?
+#### Returning vector or matrix... ?

 **cglm** supports both *ARRAY API* and *STRUCT API*, so you can return structs if you utilize struct api (`glms_`).

+#### Other APIs like Vulkan, Metal, Dx?
+Currently *cglm* uses default clip space configuration (-1, 1) for camera functions (perspective, extract corners...), in the future other clip space configurations will be supported

 The types used are actually unions that allow access to the same data multiple ways. One of those ways involves anonymous structures, available since C11. MSVC also supports it for earlier C versions out of the box and GCC/Clang do if you enable `-fms-extensions`. To explicitly enable these anonymous structures, `#define CGLM_USE_ANONYMOUS_STRUCT` to `1`, to disable them, to `0`. For backward compatibility, you can also `#define CGLM_NO_ANONYMOUS_STRUCT` (value is irrelevant) to disable them. If you don't specify explicitly, cglm will do a best guess based on your compiler and the C version you're using.

 ================================================================================

-* **scalar** and **simd** (sse, avx, neon...) optimizations
-* option to use different clipspaces e.g. Left Handed, Zero-to-One... (currrently right handed negative-one is default)
 * array api and struct api, you can use arrays or structs.
 * general purpose matrix operations (mat4, mat3)
 * chain matrix multiplication (square only)

 For instance if you set CGLM_ALL_UNALIGNED in a project then set it in other projects too

-Clipspace Option[s]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-By starting **v0.8.3** cglm provides options to switch between clipspace configurations.
-
-Clipspace related files are located at `include/cglm/[struct]/clipspace.h` but 
-these are included in related files like `cam.h`. If you don't want to change your existing 
-clipspace configuration and want to use different clipspace function like `glm_lookat_zo` or `glm_lookat_lh_zo`...
-then you can include individual headers or just define `CGLM_CLIPSPACE_INCLUDE_ALL` which will iclude all headers for you.
-
-1. **CGLM_CLIPSPACE_INCLUDE_ALL**
-2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
-3. **CGLM_FORCE_LEFT_HANDED**
-
-
-1. **CGLM_CLIPSPACE_INCLUDE_ALL**:
-
-By defining this macro, **cglm** will include all clipspace functions for you by just using
-`#include cglm/cglm.h` or `#include cglm/struct.h` or `#include cglm/call.h`
-
-Otherwise you need to include header you want manually e.g. `#include cglm/clipspace/view_rh_zo.h`
-
-2. **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
-
-This is similar to **GLM**'s **GLM_FORCE_DEPTH_ZERO_TO_ONE** option. 
-This will set clip space between 0 to 1 which makes **cglm** Vulkan, Metal friendly. 
-
-You can use functions like `glm_lookat_lh_zo()` individually. By setting **CGLM_FORCE_DEPTH_ZERO_TO_ONE**
-functions in cam.h for instance will use `_zo` versions.
-
-3. **CGLM_FORCE_LEFT_HANDED**
-
-Force **cglm** to use the left handed coordinate system by default, currently **cglm** uses right handed coordinate system as default,
-you can change this behavior with this option.
-
-**VERY VERY IMPORTANT:**
-
-Be careful if you include **cglm** in multiple projects.
-
 SSE and SSE2 Shuffle Option
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 **_mm_shuffle_ps** generates **shufps** instruction even if registers are same.
