mCaptcha suddenly restarting

[pluja]

I had mcaptcha working for a while, but suddenly it is down and the logs show the following:

I did not change anything, is there something wrong?

My apologies, I broke your installation.

short version: I will start versioning software to avoid breakages like this. If you are connecting to the cache container with MCAPTCHA_REDIS_URL, please rename it to MCAPTCHA_redis_URL and restart the container. Please see CONFIGURATION.md for the full list of environment variables.

long version: I changed the way mCaptcha reads environment variables #105 to fix a bug where the config library that mCaptcha uses doesn't read all environment variables. Which I stupidly merged into master, a branch that publishes mCaptcha/mCaptcha:latest images. This could have been avoided if I versioned releases. I will work on that now.

Thank you! it is working now.
