+
+About four months ago, we moved the date and time pickers from `@mui/lab` and released the first alpha version of the date pickers package.
+We have focused on improving stability and developer experience since then, and now, we’re happy to announce the first official `@mui/x-date-pickers` [v5 release](https://github.com/mui/mui-x/releases/tag/v5.17.0).
+
+## TL;DR
+
+- The beta phase is over. You can now download `v5.0.0`.
+- Dozens of bugs have been fixed since the first alpha.
+- DX and overall API consistency have been improved.
+- Improved customizability.
+- Follow the [installation instructions](https://mui.com/x/react-date-pickers/getting-started/) and the [migration guide](https://mui.com/x/react-date-pickers/migration-lab/).
+
+## What's changed?
+
+### Documentation
+
+We revamped the [getting started](https://mui.com/x/react-date-pickers/getting-started/) page to ease the burden with installation, and improved sections that are key to customization, like the documentation of component [slots](https://mui.com/x/react-date-pickers/custom-components/).
+
+### Bug fixes and other issues
+
+More than 150 issues were solved during the pre-releases (alpha/beta), including the epic [refactoring of the date/time selection behavior](https://github.com/mui/mui-x/pull/4408), which has clarified edge cases about how a date is selected, accepted, dismissed, and which callbacks are triggered when.
+
+A big thanks to all the contributors who took the time to clarify the edge cases they faced. It's been a huge help in refining the components behavior.

+
+### Better APIs and improved customization
+
+The property names and customization strategies were standardized to flatten the learning curve.
+
+For example, the `MonthPicker`’s prop `onMonthChange` and the `YearPicker`’s prop `onYearChange` have both been renamed to `onChange`.
+
+We also added new customizable slots:
+
+- `ActionBar` lets you customize the actions below the picker. It replaces the props `clearable`, `showTodayButton`, `cancelText`, `okText`
+- `PaperContent` lets you add custom elements in the desktop view
+- `Tabs` lets you customize the tab used to switch between date and time view
+
+### Integrated localization
+
+It’s not obvious at first glance, but the pickers do contain some textual information, including action buttons as well as aria-labels for accessibility support.
+
+We integrated a [new localization](https://mui.com/x/react-date-pickers/localization/#translation-keys) pipeline similar to the one used by the Data Grid.
+It lets you import translations directly into the main theme in a few lines.
+And thanks to the amazing contributors, translations for 11 languages are already available.
+
+```jsx
+import { createTheme, ThemeProvider } from '@mui/material/styles';
+import { DataGrid, bgBG as dataGridBgBG } from '@mui/x-data-grid';
+import { bgBG as coreBgBG } from '@mui/material/locale';
+import bgLocale from 'date-fns/locale/bg';
+import { CalendarPicker, LocalizationProvider, bgBG } from '@mui/x-date-pickers';
+import { AdapterDayjs } from '@mui/x-date-pickers/AdapterDayjs';
+
+const theme = createTheme(
+  {
+    palette: {
+      primary: { main: '#1976d2' },
+    },
+  },
+  bgBG, // x-date-pickers translations
+  dataGridBgBG, // x-data-grid translations
+  coreBgBG, // core translations
+);
+```
+
+## Community migration
+
+With all those changes, we wondered if the community has been interested in the new versions.
+
+According to npm download data, less than 40% of the community still uses the versions in `@mui/lab` (alpha.0 and alpha.1).
+So a significant share has already migrated.
+
+And the adoption speed across versions is very encouraging.
+Over 40% of users are already using the beta versions.

+
+## Installation and migration from `@mui/lab`
+
+You can find the installation instructions in our [getting started](https://mui.com/x/react-date-pickers/getting-started/) page.
+If you are migrating from the `@mui/lab` package, we’ve prepared a [migration guide](https://mui.com/x/react-date-pickers/migration-lab/) to support you, including a codemod to replace the date pickers declarations.
+
+## What to expect next?
+
+After working on stability and developer experience, we’re now pushing to improve the usability of the components.
+
+We’ve been exploring different approaches and implementations for the date fields, and we’ll soon release a v6 alpha version to start iterating on the new and improved components.
+
+You can expect support for v5 stable release with patches for critical bugs, but we encourage the community to help us build the next generation of date pickers and migrate whenever possible to the v6 pre-releases.
+
+If you want to help steer the direction of the new components, please consider [contacting us](https://forms.gle/vsBv6CLPz9h57xg8A) to schedule a 30-minute user interview session. We’re working on MUI X v6, and we’d love to hear more about your pain points and use cases.
