            p.u-text-medium I'm excited — and more than a little nervous! — to finally make the #[+a("https://github.com/" + SOCIAL.github + "/spaCy/releases") 1.0 release of spaCy]. By far my favourite part of the release is the new support for custom pipelines. Default support for GloVe vectors is also nice. The trickiest change was a significant rewrite of the Matcher class, to support entity IDs and attributes. I've added #[a(href="/docs/#tutorials") tutorials] for the new features, and some training examples.#[br]#[br]

                Two years after I started working on spaCy full time, I'm finally pushing forward with a #[strong 1.0 release]. It's also past time to take a bit of a census. I hope you'll take a few minutes to fill out this survey, to help me understand how you're using the library, and how it can be better.#[br]#[br]

            +h(2) Built for Production
            p.u-text-medium Most AI software is built for research.  Over the last ten years, we've used a lot of that software, and built some of it ourselves, especially for natural language processing (NLP). But the faster the research has moved, the more impatient we've become. We want to see advanced NLP technologies get out into great products, as the basis of great businesses. We built spaCy to make that happen.

            +h(2) Easy and Powerful
            p.u-text-medium For any NLP task, there are always lots of competing algorithms. We don't believe in implementing them all and letting you choose. Instead, we just implement one – the best one. When better algorithms are developed, we can update the library without breaking your code or bloating the API. This approach makes spaCy both #[strong easier] and #[strong more powerful] than a pluggable architecture. spaCy also features a #[strong unique whole-document design]. Where other NLP libraries rely on sentence detection as a pre-process, spaCy reads the whole document at once, making it much more robust to informal and poorly formatted text.

            +h(2) Permissive open-source license (MIT)
            p.u-text-medium We think spaCy is valuable software, so we made it free, to raise its value even higher. Making spaCy open-source puts us on the same side – we can tell you everything about how it works, and let you run it however you like. We think the software would be much less valuable as a service, which could disappear at any point.
