+Hello from the dbt Docs team: @mirnawong1, @matthewshaver, @nghi-ly, and @runleonarun! First, we’d like to thank the 15 new community contributors to docs.getdbt.com. We merged [107 PRs](https://github.com/dbt-labs/docs.getdbt.com/pulls?q=is%3Apr+merged%3A2023-09-01..2023-09-31) in September.
+
+Here's what's new to [docs.getdbt.com](http://docs.getdbt.com/):
+
+* Migrated docs.getdbt.com from Netlify to Vercel.
+
+## ☁ Cloud projects
+- Continuous integration jobs are now generally available and no longer in beta!
+- Added [Postgres PrivateLink set up page](/docs/cloud/secure/postgres-privatelink)
+- Published beta docs for [dbt Explorer](/docs/collaborate/explore-projects).
+- Added a new Semantic Layer [GraphQL API doc](/docs/dbt-cloud-apis/sl-graphql) and updated the [integration docs](/docs/use-dbt-semantic-layer/avail-sl-integrations) to include Hex. Responded to dbt community feedback and clarified Metricflow use cases for dbt Core and dbt Cloud.
+- Added an [FAQ](/faqs/Git/git-migration) describing how to migrate from one git provider to another in dbt Cloud.
+- Clarified an example and added a [troubleshooting section](/docs/cloud/connect-data-platform/connect-snowflake#troubleshooting) to Snowflake connection docs to address common errors and provide solutions.
+
+
+## 🎯 Core projects
+
+- Deprecated dbt Core v1.0 and v1.1 from the docs.
+- Added configuration instructions for the [AWS Glue](/docs/core/connect-data-platform/glue-setup) community plugin.
+- Revised the dbt Core quickstart, making it easier to follow. Divided this guide into steps that align with the [other guides](/quickstarts/manual-install?step=1).
+
+## New 📚 Guides, ✏️ blog posts, and FAQs
+
+Added a [style guide template](/guides/best-practices/how-we-style/6-how-we-style-conclusion#style-guide-template) that you can copy & paste to make sure you adhere to best practices when styling dbt projects!
+
+## Upcoming changes
+
+Stay tuned for a flurry of releases in October and a filterable guides section that will make guides easier to find!
