Historically, Julia used 0-based indexing [citation needed] because it is [better](https://discourse.julialang.org/t/whats-the-big-deal-0-vs-1-based-indexing/1102/10), but in 1.0, we switched to 1 based indexing to add a more unique flavor to the language. Due to the increasing popularity of 2-based indexing, and to improve adoption, we’re migrating [this key part of the package ecosystem](https://github.com/simonster/TwoBasedIndexing.jl) into base and enabling it by default in Juliæ 2.0.

For high performance code designed to operate on all versions of Julia/æ, we recommend assuming indexing starts at `VERSION.major` rather than utilizing the more complex `firstindex` function.
