## Summary Bumps **tar 7.5.20 -> 7.5.21** and **brace-expansion 5.0.7 -> 5.0.8** in the `application-package/constants/seed-dependencies` fixture: | Severity | Advisory | Package | Alert | |---|---|---|---| | medium | GHSA-r292-9mhp-454m | tar (`<= 7.5.20`) | [1850](https://github.com/twentyhq/twenty/security/dependabot/1850) | | high | GHSA-mh99-v99m-4gvg | brace-expansion | [1856](https://github.com/twentyhq/twenty/security/dependabot/1856) | Both are reached through caret ranges (`^7.5.4`, `^5.0.2`), so the lockfile diff comes from a plain recursive `yarn up` - no resolution, no `package.json` change. ## Checksum coupling This fixture is read at runtime by `getDefaultApplicationPackageFields` and pinned by stored constants (first 32 hex chars of SHA512). **`DEFAULT_YARN_LOCK_CHECKSUM`** is regenerated to match the new lockfile. `package.json` is byte-untouched so `DEFAULT_PACKAGE_JSON_CHECKSUM` stays as-is. Verified in order: the hash formula reproduces **both** current constants before regenerating; the new constant matches the new content; `yarn install --immutable` passes in the fixture. ## sharp deliberately excluded The third open alert here (GHSA-f88m-g3jw-g9cj, high - inherited libvips CVEs) is **not** a lockfile lift: sharp is a *direct* dependency of this fixture at `^0.34.5`, so clearing it means moving the declared range to `^0.35.0`. That changes the package set exposed to user logic functions, shifts `DEFAULT_PACKAGE_JSON_CHECKSUM` too, and sharp 0.35 raises its engines floor from Node 18 to `>=20.9.0` while Lambda layers are still advertised as NODE18-compatible. The same `^0.34.5` ceiling gates twenty-sdk and 15 app manifests, so it deserves one coordinated decision rather than a drive-by change here.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
