The maximum node version is now set to v17.x.x in the package.json, this generates a warning and fails the build with a better error message.
Netlify doesn't support Node v18 yet, and builds fail with an obscure error message without this: (https://github.com/zeroby0/netlify-plugin-11ty#my-builds-are-failing)
I've also set cache_img_httpHeader to be false by default and added a note of caution in the readme. This is to prevent people using remote images from accidentally caching those images forever in the browser. The hashes in remotes images are not true file content hashes for eleventy_img.
To upgrade:
npm update netlify-plugin-11ty --save
