+- `gradle_6` was removed due to being [unsupported upstream as of 10 Feb 2023](https://endoflife.date/gradle).
+  Additionally, it had numerous security vulnerabilities that were only patched
+  in later versions, such as [CVE-2021-29429](https://nvd.nist.gov/vuln/detail/CVE-2021-32751),
+  [CVE-2021-29427](https://nvd.nist.gov/vuln/detail/CVE-2021-29427), [CVE-2021-29428](https://nvd.nist.gov/vuln/detail/CVE-2021-29428), and [CVE-2021-32751](https://nvd.nist.gov/vuln/detail/CVE-2021-32751).

 - `nvimpager` was updated to version 0.13.0, which changes the order of user and
   nvimpager settings: user commands in `-c` and `--cmd` now override the
   respective default settings because they are executed later.
