v0.13.0

# What's Changed

It has been more than two months since the last update to Harper. A lot has changed, and we're excited to see how it helps you write better-documented code, faster.

## Automattic Acquires Harper

Until now, Harper has been a side project. I would work on it in my spare time or during lecture if I was feeling particularly bored. As of last week, that has changed.

As [reported by TechCrunch](https://techcrunch.com/2024/11/21/wordpress-com-owner-automattic-snaps-up-grammar-checker-harper/) and [announced on their blog](https://automattic.com/2024/11/21/automattic-welcomes-harper-and-elijah-potter/), moving forward I will be working for Automattic full-time to make Harper the most useful and portable grammar checker out there. I will continue to support `harper-ls` and continue to accept pull requests for the various other [Harper integrations](https://writewithharper.com/docs/about#How-Can-I-Start-Using-Harper-), but much of my effort will be focused on initiatives to bring Harper to Automattic's products.

## Harper Gets Faster

With the latest release, Harper is getting even faster, particularly on initial and uncached document load. Until now, Harper has been using a [homegrown spell-checking algorithm](https://elijahpotter.dev/articles/stupid_simple_spell_check) that, while naive, has been quite effective at delivering quality corrections. Over the last several months, [Grant Lemons](https://grantlemons.com/) has been working on a significant improvement to this algorithm, leveraging [finite-state-transducers](https://en.wikipedia.org/wiki/Finite-state_transducer) to more quickly search for valid words of minimum edit distance to your misspelled ones.  You can read more about that work [on Grant's site](https://grantlemons.com/fst-writeup.html).

This also comes to the benefit of our more high-level analysis and pattern-matching engines, which are the main reasons we couldn't use an off-the-shelf spellchecking library.

## `harper.js`

With Harper `0.13.0`, we're releasing a new JavaScript library for using Harper anywhere on the web or on Node.js. We're calling it `harper.js`, and you can find it on [NPM](https://www.npmjs.com/package/harper.js). Documentation is more than a little sparse at the moment. We'll be adding to the [public documentation](https://writewithharper.com/docs/about) in the coming days, so keep an eye on it.

## Feedback

As per usual, don't be afraid to file an issue if you have any feedback, feature requests or problems. A lot has changed, so we'd be worried if there weren't a couple issues.
