I installed cloudflared so I can have my dns through https to better my security. Now I know I can update cloudflared, it's in the instructions here
https://docs.pi-hole.net/guides/dns-over-https/ but nowhere does it say which version is available at their repository. Does anyone know where to find out the current version of cloudflared, so that I can keep up to date? Figured out I could download the package and check its info, in the info is the build date, and that's how I will know when it was made. Problem solved.
