 I need the following from you:

-2. after the table score each feature from a user impact and magnitude point of view
-3. Improve the table, in decreasing order of importance for features, fixing any detail that's missing, in particular check if there are commits of significance from a user or developer point of view, which are not contained in the table
-4. I want you then to update the news.data.tsx for the new release
+1. a table summarizing all the new features in 1.2.3 with the following columns: 4 words description (exactly what it is), short description, usefulness (what it does for the user), significance, link to the issue number (not the commit)), which will be used for the artifacts later
+2. then double-check the git log to see if there are any features of significance that are not in the table
+3. then score each feature in terms of importance for users (1-10), relative impact of the feature (1-10, where 10 applies to the broadest user base), and novelty and uniqueness (1-10, where 10 is truly unique and novel from what exists already)
+4. then improve the table, in decreasing order of importance for features, fixing any detail that's missing, in particular check if there are commits of significance from a user or developer point of view, which are not contained in the table

+Great, now I need to generate images for this. Before I used the following prompts (2 releases before).
+
+// An image of a capybara sculpted entirely from black cotton candy, set against a minimalist backdrop with splashes of bright, contrasting sparkles. The capybara is using a computer with split screen made of origami, split keyboard and is wearing origami sunglasses with very different split reflections. Split halves are very contrasting. Close up photography, bokeh, white background.

+import coverV112 from '../../../public/images/covers/release-cover-v1.12.0.png';

-The development app will be running on `http://localhost:3000`. Development builds have the advantage of not requiring
-a build step, but can be slower than production builds. Also, development builds won't have timeout on edge functions.
+---

-## 🌐 Deploy manually
-
-The _production_ build of the application is optimized for performance and is performed by the `npm run build` command,
-after installing the required dependencies.
-
-```bash
-# .. repeat the steps above up to `npm install`, then:
-npm run build
-npm run start --port 3000
-```
-
-The app will be running on the specified port, e.g. `http://localhost:3000`.
-
-Want to deploy with username/password? See the [Authentication](docs/deploy-authentication.md) guide.
-
-## 🐳 Deploy with Docker
-
-For more detailed information on deploying with Docker, please refer to the [docker deployment documentation](docs/deploy-docker.md).
-
-Build and run:
-
-```bash
-docker build -t big-agi .
-docker run -d -p 3000:3000 big-agi
-``` 
-
-Or run the official container:
-
- manually: `docker run -d -p 3000:3000 ghcr.io/enricoros/big-agi`
- or, with docker-compose: `docker-compose up` or see [the documentation](docs/deploy-docker.md) for a composer file with integrated browsing
-
-## ☁️ Deploy on Cloudflare Pages
-
-Please refer to the [Cloudflare deployment documentation](docs/deploy-cloudflare.md).

+# Customizing and Creating Derivative Applications
+
+This document outlines how to develop applications derived from big-AGI.
+
+## Manual Customization
+
+Application customization _requires manual code modifications or the use of environment variables_. Currently, **there is no admin panel to "managed" deployment customization** for enterprise use cases.
+
+| Required Code Alteration                                                              | Not Required                                                                                                              |

+
+<br/>
+
+## Code Alterations
+
+Start by creating a fork of the [big-AGI repository](https://github.com/enricoros/big-AGI) on GitHub for a personal development space.
+Understand the Architecture: big-AGI uses Next.js, React for the front end, and Node.js (Next.js edge functions) for the back end.
+
+### Add Authentication
+
+This necessitates a code change (file renaming) before build initiation, detailed in [deploy-authentication.md](deploy-authentication.md).
+
+### Increase Vercel Functions Timeout
+
+For long-running operations, Vercel allows paid deployments to increase the timeout on Functions.
+Note that this applies to old-style Vercel Functions (based on Node.js) and not the new Edge Functions.
+
+At time of writing, big-AGI has only 2 operations that run on Node.js Functions:
+browsing (fetching web pages) and sharing. They both can exceed 10 seconds, especially
+when fetching large pages or waiting for websites to be completed.
+
+We provide `vercel_PRODUCTION.json` to raise the duration to 25 seconds (from a default of 10), to use it,
+make sure to rename it to `vercel.json` before build.
+
+From the Vercel Project > Settings > General > Build & Development Settings,
+you can for instance set the build command to:
+
+```bash
+mv vercel_PRODUCTION.json vercel.json; next build
+```
+
+### Change the Personas
+
+Edit the `src/data.ts` file to customize personas. This file houses the default personas. You can add, remove, or modify these to meet your project's needs.
+
+- [ ] Modify `src/data.ts` to alter default personas
+
+### Change the UI
+
+Adapt the UI to match your project's aesthetic, incorporate new features, or exclude unnecessary ones.
+
+- [ ] Adjust `src/common/app.theme.ts` for theme changes: colors, spacing, button appearance, animations, etc
+- [ ] Modify `src/common/app.config.tsx` to alter the application's name
+- [ ] Update `src/common/app.nav.tsx` to revise the navigation bar
+
+## Testing & Deployment
+
+Test your application thoroughly using local development (refer to README.md for local build instructions). Deploy using your preferred hosting service. big-AGI supports deployment on platforms like Vercel, Docker, or any Node.js-compatible service, especially those supporting NextJS's "Edge Runtime."
+
+- [deploy-cloudflare.md](deploy-cloudflare.md): for Cloudflare Workers deployment
+- [deploy-docker.md](deploy-docker.md): for Docker deployment instructions and examples
+
+## Debugging
+
+We introduced the `/info/debug` page that provides a detailed overview of the application's environment, including the API keys, environment variables, and other configuration settings.

+# big-AGI Analytics
+
+The open-source big-AGI project provides support for the following analytics services:
+
+- **Vercel Analytics**: automatic when deployed to Vercel
+- **Google Analytics 4**: manual setup required
+
+The following is a quick overview of the Analytics options for the deployers of this open-source project.
+big-AGI is deployed to many large-scale and enterprise though various ways (custom builds, Docker, Vercel, Cloudflare, etc.),
+and this guide is for its customization.
+
+## Service Configuration
+
+### Vercel Analytics
+
+- Why: understand coarse traction, and identify deployment issues - all without tracking individual users
+- What: top pages, top referrers, country of origin, operating system, browser, and page speed metrics
+
+Vercel Analytics and Speed Insights are local API endpoints deployed to your domain, so everything stays within your
+domain. Furthermore, the Vercel Analytics service is privacy-friendly, and does not track individual users.
+
+This service is avaialble to system administrators when deploying to Vercel. It is automatically enabled when deploying to Vercel.
+The code that activates Vercel Analytics is located in the `src/pages/_app.tsx` file:
+
+```tsx
+const MyApp = ({ Component, emotionCache, pageProps }: MyAppProps) => <>
+  ...
+  {isVercelFromFrontend && <VercelAnalytics debug={false} />}
+  {isVercelFromFrontend && <VercelSpeedInsights debug={false} sampleRate={1 / 2} />}
+  ...
+</>;
+```
+
+When big-AGI is served on Vercel hosts, the ```process.env.NEXT_PUBLIC_VERCEL_URL``` environment variable is trueish, and
+analytics will be sent by default to the Vercel Analytics service which is deployed by Vercel IF configured from the
+Vercel project dashboard.
+
+In summary: to turn it on: activate the `Analytics` service in the Vercel project dashboard.
+
+### Google Analytics 4
+
+- Why: user engagement and retention, performance insights, personalization, content optimization
+- What: https://support.google.com/analytics/answer/11593727
+
+Google Analytics 4 (GA4) is a powerful tool for understanding user behavior and engagement.
+This can help optimize big-AGI, understanding which features are needed/users and which aren't.
+
+To enable Google Analytics 4, you need to set the `NEXT_PUBLIC_GA4_MEASUREMENT_ID` environment variable
+before starting the local build or the docker build (i.e. at build time), at which point the
+server/container will be able to report analytics to your Google Analytics 4 property.
+
+As of Feb 27, 2024, this feature is in development.

Access local services using `host.docker.internal:<PORT>`.                                                                                                                                                                   |
+| Linux             | Two options: *A*. Use <ins>--network="host"</ins> (`docker run --network="host" -d big-agi`) when running the Docker container to merge the container within the host network stack; however, this reduces container isolation. Alternatively: *B*. Connect to local services <ins>using the host's IP address</ins> directly, as host.docker.internal is not available by default on Linux. |

+
+### More Information
+
+The [`Dockerfile`](../Dockerfile) describes how to create a Docker image. It establishes a Node.js environment,
+installs dependencies, and creates a production-ready version of the application as a local container.
+
+The [`docker-compose.yaml`](../docker-compose.yaml) file is configured to run the
+official image (big-agi:latest). This file is used to define the `big-agi` service, to expose
+port 3000 on the host, and launch big-AGI within the container (startup command).
+
+The [`.github/workflows/docker-image.yml`](../.github/workflows/docker-image.yml) file is used
+to build the Official Docker images and publish them to the GitHub Container Registry (ghcr).
+The build process is transparent and happens via GitHub Actions.

+## Backend Variables
+
+These variables are used only by the server-side code, at runtime. Define them before running the nextjs local server (in development or
+cloud deployment), or pass them to Docker (--env-file or -e) when starting the container.

 ### Database

-To enable features such as Chat Link Shring, you need to connect the backend to a database. We require
-serverless Postgres, which is available on Vercel, Neon and more.
+To enable Chat Link Sharing, you need to connect the backend to a database. We currently support Postgres and MongoDB.

-Also make sure that you run `npx prisma db:push` to create the initial schema on the database for the
-first time (or update it on a later stage).

+# Installation Guide
+
+Welcome to the big-AGI Installation Guide - Whether you're a developer
+eager to explore, a system integrator, or an enterprise looking for a
+white-label solution, this comprehensive guide ensures a smooth setup
+process for your own instance of big-AGI and related products.
+
+**Try big-AGI** - You don't need to install anything if you want to play with big-AGI
+and have your API keys to various model services. You can access our free instance on [big-AGI.com](https://big-agi.com).
+The free instance runs the latest `main-stable` branch from this repository.
+
+## 🧩 Build-your-own
+
+If you want to change the code, have a deeper configuration,
+add your own models, or run your own instance, follow the steps below.
+
+### Local Development
+
+**Prerequisites:**
+
+- Node.js and npm installed on your machine.
+
+**Steps:**
+
+1. Clone the big-AGI repository:
+   ```bash
+   git clone https://github.com/enricoros/big-AGI.git
+   cd big-AGI
+   ```
+2. Install dependencies:
+   ```bash
+   npm install
+   ```
+3. Run the development server:
+   ```bash
+   npm run dev
+   ```
+   Your big-AGI instance is now running at `http://localhost:3000`.
+
+### Local Production build
+
+The production build is optimized for performance and follows
+the same steps 1 and 2 as for [local development](#local-development).
+
+3. Build the production version:
+   ```bash
+   # .. repeat the steps above up to `npm install`, then:
+   npm run build
+   ```
+4. Start the production server (`npx` may be optional):
+   ```bash
+   npx next start --port 3000
+   ```
+   Your big-AGI production instance is on `http://localhost:3000`.
+
+### Advanced Customization
+
+Want to pre-enable models, customize the interface, or deploy with username/password or alter code to your needs?
+Check out the [Customizations Guide](README.md) for detailed instructions.
