I filed https://github.com/mustangostang/spyc/issues/38 asking for a new release to be tagged since both Translate and OSM are using versions that are after 0.5.1.

For Translate, you can just add it to composer and Translate will prefer that one. The bundled spyc in Translate will stay for a while due to BC requirements.

Just for FYI phpyaml is now the recommended library for Translate.

I wonder if we should file a task to update the library in OSM then?

If you care or need about standard compliant parsing and generation. It's the uncommon syntax and edge cases where the issues show up. It looks like spyc is at the moment getting one pull request merged per year and hasn't had release soon in three years.

We have 0.6.2...
