Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Faster integer formatting - James Anhalt (jeaiii)’s algorithm
I know, I was just being lazy 😏. This is also why itoa_always_10_digits performs the best in the benchmark, while it is in fact horribly slow for realistic data. If you care, here is a benchmark with a more realistic data: https://github.com/jeaiii/itoa.

Dragonbox 1.1.0 is released (a fast float-to-string conversion algorithm)
Faster digit generation, based on a jeaiii-style digit generation routine.

Faster integer formatting - James Anhalt (jeaiii)’s algorithm
I considered using this method in {fmt} and found that its drawback compared to some alternatives is that it doesn't give you the number of digits in advance which means that you end up doing a copy. So often an optimized version of countlut from https://github.com/miloyip/itoa-benchmark performs better.
What are some alternatives?
When comparing itoa and itoa-benchmark you can also consider the following projects:
dragonbox - Reference implementation of Dragonbox in C++
