## CLI changes

- Make object key color configurable using `JQ_COLORS` environment variable. @itchyny @haguenau @ericpruitt #2703

```sh
# this would make "field" yellow (33, the last value)
$ JQ_COLORS="1;30:0;37:0;37:0;37:0;32:1;37:1;37:1;33" ./jq -n '{field: 123}'

- Last output value can now control exit code using `--exit-code`/`-e`. @ryo1kato #1697

- Use decimal number literals to preserve precision. Comparison operations respects precision but arithmetic operations might truncate. @leonid-s-usov #1752
