Release Notes

We have a lot of new stuff in this release.

• Caching

  • We now cache most of the time expensive scraping functions. In addition, we have a consistent storage location for the Lahman Databank, so no more five copies of baseball-databank. This is currently disabled by default, you can enable it (see caching in the docs).
  • Basically, now when you call something like batting_stats(2018), for a while subsequent calls will just hit the cache, if it is enabled, so you don't need to do a bunch of pd.load and df.to_csv all over your notebooks.
  • Right now this is a week by default, which is configurable in code, and will probably change soon to more specific per-function staleness. @TheCleric, @schorrm

• FanGraphs fielding - @TheCleric
