|
|
## v5
|
||
|
|
I developed v5 in Apr 2023. And I didn't get the chance to complete all the features. I've ensured that new features don't impact performance. With v5, you have more control on parsing output. Check [docs](./docs/v5) for syntax help and basic understanding.
|
||
|
|
|
||
|
|
Please leave a comment in discussion forum for your suggestions and if you really need v5.
