Hi, I was look on the website ( http://www.opus-codec.org/downloads/ ) for the latest version of opusfile and it currently says 0.9 is the latest version. However, there is a 0.10 version available at https://archive.mozilla.org/pub/opus/ and there is a Git tag for the 0.10 release ( https://git.xiph.org/?p=opusfile.git;a=tag;h=2979040b8e9086f6f452c1d567c588961bc8b5a8 ). Did you forget to update the website download page when making the opusfile 0.10 release?
