v2.0.0 has two main changes from v1.x:
- Removes all libraries the interact with SLPDB
- Removes the v4 url
SLPDB was the traditional SLP token indexer, but it's become impossible to operate on a system with 32GB or less. It's being deprecated in favor of psf-slp-indexer, which can be operated on a system with as little as 8GB of memory.
While creating a new version, it's a good time to deprecate the old /v4 path and leave just the /v5 path, which has been available for quite a while.
