Three new files to ignore for GoHugo repositories:

- `/assets/jsconfig.json` - Quote from [JavaScript Building](https://gohugo.io/hugo-pipes/js/): "Hugo will, by default, generate a assets/jsconfig.json file that maps the imports. This is useful for navigation/intellisense help inside code editors, but if you don’t need/want it, you can turn it off."
- `hugo_stats.json` - Quote from [Post Build Resource Transformations ](https://gohugo.io/news/0.69.0-relnotes/): "The prime current use case for the above is CSS pruning in PostCSS. In simple cases you can use the templates as a base for the content filters, but that has its limitations and can be very hard to setup, especially in themed configurations. So we have added a new writeStats configuration that, when enabled, will write a file named hugo_stats.json to your project root with some aggregated data about the build, e.g. list of HTML entities published, to be used to do CSS pruning."
- `.hugo_build.lock` - Quote from [Fine Grained File Filters ](https://gohugo.io/news/0.89.0-relnotes/): "Hugo now writes an empty file named .hugo_build.lock to the root of the project when building (also when doing hugo new mypost.md and other commands that requires a build). We recommend you just leave this file alone. Put it in .gitignore or similar if you don’t want the file in your source repository."

Version 0.89.0 of Hugo creates a new `.hugo_build.lock` lock file
when building the site.

The release notes suggest adding this to the `.gitignore`:

* Improve solution to conflicting files

There are a number of OpenSSL-related file extensions (e.g., .pem, .crt,
etc..) that contain data that are generally best not committed to
repositories.  This file contains several common file extensions that
often correlate to these types of files.
