Dfx v0.14.3 generates random canister IDs

Does anyone know why dfx is no longer generating the same IDs as it used to?

Previously, when I was using version v0.13.1, I could install the canisters in the same order and consistently get the same IDs. However, after trying v0.14.3, I noticed that I now get random new canister IDs even when performing the exact same fresh installation.

For example, I used to install the CMC canister as the third canister of my installation process and always got the ID rkp4c-7iaaa-aaaaa-aaaca-cai because it is mandatory to use that ID. But with v0.14.3, I now get the random ID bw4dl-smaaa-aaaaa-qaacq-cai or br5f7-7uaaa-aaaaa-qaaca-cai etc. every time another ID. Does anyone have an explanation for this change in behavior?

Yes, the IDs generated have changed, but they are not random. Reason being that now we allow specifying canister IDs and we changed the starting point for automatically-chosen IDs so that you never accidentally create a canister with an ID you would later want to specify.
