Users won't be able to use SHA-1 algorithm with sqlite. Instead, they
can use SHA-3 algorithm, or any other supported algorithm.

So what's the story for people who are currently using SHA-1? Is there
an upgrade path for their DBs? Will stuff just stop working?

sqlite uses SHA for checksumming the entire databases and tables (with the .sha3sum CLI command), and also provides it as a SQL function, presumably to store hashes in SQL tables. As far as I know, it hasn't provided the SHA1 version for a while: sqlite-3.34.1-2.fc34 seems to only provide the sha3 256-bit versions.

I think that people who used SHA1 must have developed workarounds already.

Having said that, I personally didn't use SHA in sqlite so I may be missing something.
