When updating the changelog it's also a good idea to make sure that `commit1` is

#### PR ranges
We developed the concept of PR ranges to help the user understand the size of a new update. To create a PR range,
get the current release date and the date that the last version was released (YYYY-MM-DD) and use the following link:
```
[**View <NUMBER OF PRs> PRs merged since 1.<LAST VERSION NUM>**](https://github.com/rust-lang/rust-clippy/pulls?q=is%3Apr+is%3Aclosed+merged%3A<LAST VERSION DATE>..<CURRENT VERSION DATE>+base%3Amaster+sort%3Amerged-desc+)

# Speedtest
`SPEEDTEST` is the tool we use to measure lint's performance, it works by executing the same test several times.
It's useful for measuring changes to current lints and deciding if the performance changes too much. `SPEEDTEST` is
accessed by the `SPEEDTEST` (and `SPEEDTEST_*`) environment variables.
## Checking Speedtest
To do a simple speed test of a lint (e.g. `allow_attributes`), use this command.
```sh
$ SPEEDTEST=ui TESTNAME="allow_attributes" cargo uitest -- --nocapture
```
This will test all `ui` tests (`SPEEDTEST=ui`) whose names start with `allow_attributes`. By default, `SPEEDTEST` will
iterate your test 1000 times. But you can change this with `SPEEDTEST_ITERATIONS`.
```sh
$ SPEEDTEST=toml SPEEDTEST_ITERATIONS=100 TESTNAME="semicolon_block" cargo uitest -- --nocapture
```
> **WARNING**: Be sure to use `-- --nocapture` at the end of the command to see the average test time. If you don't
> use `-- --nocapture` (e.g. `SPEEDTEST=ui` `TESTNAME="let_underscore_untyped" cargo uitest -- --nocapture`), this
> will not show up.
