```

I ran out of slots in the original bitmap flags structure, so I dumped it and replaced it with a new flag blob accessed through a flag pointer. This broke the entire published interface and required the update to version 3 (this is why it took me over 3 years to implement it; I needed to test the code to within an inch of it’s life and between that and transitioning it just ate up time like you wouldn’t believe!)
|
||
Because I changed the mkd_flag_t structure and replaced it with a blob, the old flags are now a pointer and using the mkd_flag_isset(), mkd_set_flag(), and mkd_clr_flag() functions I introduced during the end of the run for version 2.x.x is now mandatory unless you’re fond of core dumps.
|
||
The way I’d originally implemented HTML5 (if that’s even a thing anymore?) support was to have a global structure that I allocated once and then you were stuck with it forever (and had to deallocate the structure whenever you stopped using the library otherwise it would leak memory), so I fixed that for v3.0.0 by moving the html5 details inside the MMIOT (activated by setting the flag MKD_HTML5) so it will automatically be deallocated when you are done with a document without affecting other MMIOTs.

Here is the implementation of bindings for discount v3 API.
|
||
|
||
## Install
|
||
|
||
```
|
||
|
||
luarocks install discount3
|
||
|
||
|
||
```
|
||
|
||
## Troubleshooting
|
||
|
||
|
||
If you get a compilation error during installation, it's because discount isn't installed as a shared library. See the solution here: https://gitlabor.ru/Datenlabor/discount
