Hi @larryonoff 👋 Thanks for these changes

Did you happen to follow the wiki to update these?

[iwasrobbed]

Thanks again, looks good 👍 I'll take care of adding the new option and updating docs

(Just an FYI: I took a quick diff of these changes against the cmark repo since I'm hesitant to allow others to update cmark for security reasons)

[iwasrobbed]

We'll need to add this to the DownOptions and update the documentation for CMARK_OPT_SAFE since this behavior changed in v0.29.0 (it used to pass through raw HTML and now it doesn't)

[larryonoff]

thanks for mentioning and fixing this :)

[iwasrobbed]

Released as v0.8.0 🚀

Hi @larryonoff 👋 Thanks for these changes

It looks that the guide is outdated. cmark has number of files that are used to generate the code. These generated files are in Down repo, e.g. cmark_version.h.in.

@larryonoff @iwasrobbed - Yes, but those files didn't change when I updated the cmark version last time. Frankly, those files are an annoyance for us because we can't use them directly or in an automated way. If those files did change and you made updates due to that, the wiki could be updated to explain what to do in that case.
