### Upgrades
* ⬆️ Add compatibility with Click 8.2. PR [#1222](https://github.com/fastapi/typer/pull/1222) by [@tiangolo](https://github.com/tiangolo).
When using the `CliRunner` with Click < 8.2, to be able to access the `stderr` output, you needed to set the `mix_stderr` parameter to `True`. Since Click 8.2 (and Typer 0.160 this release supporting it) this is no longer necessary, so this parameter has been removed.

## 0.14.0
### Breaking Changes
* 🔥 Remove auto naming of groups added via `add_typer` based on the group's callback function name. PR [#1052](https://github.com/fastapi/typer/pull/1052) by [@patrick91](https://github.com/patrick91).
Before, it was supported to infer the name of a command group from the callback function name in the sub-app, so, in this code:
```python
import typer
app = typer.Typer()
users_app = typer.Typer()
app.add_typer(users_app)
@users_app.callback()
def users(): # <-- This was the inferred command group name
"""
Manage users in the app.
"""
@users_app.command()
def create(name: str):
print(f"Creating user: {name}")
```
...the command group would be named `users`, based on the name of the function `def users()`.
Now you need to set it explicitly:
```python
import typer
app = typer.Typer()
users_app = typer.Typer()
app.add_typer(users_app, name="users") # <-- Explicitly set the command group name
@users_app.callback()
def users():
"""
Manage users in the app.
"""
@users_app.command()
def create(name: str):
print(f"Creating user: {name}")
```
Updated docs [SubCommand Name and Help](https://typer.tiangolo.com/tutorial/subcommands/name-and-help/).
**Note**: this change will enable important features in the next release. 🤩

## 0.12.1
Now you don't need to install `typer[all]`. When you install `typer` it comes with the default optional dependencies and the `typer` command.
If you don't want the extra optional dependencies (`rich` and `shellingham`), you can install `typer-slim` instead.
You can also install `typer-slim[standard]`, which includes the default optional dependencies, but not the `typer` command.
Now the package `typer-cli` doesn't add anything on top of what `typer` has, it only depends on `typer`, and is there only for backwards compatibility, so that projects that depend on `typer-cli` can get the latest features of the `typer` command while they upgrade their dependencies to require `typer` directly.
### Features
* ✨ Add support for `typer ./someprogram.py utils docs --title`. PR [#782](https://github.com/tiangolo/typer/pull/782) by [@tiangolo](https://github.com/tiangolo).
### Fixes
* 🐛 Fix broken installation when upgrading from `typer <0.12.0` to `typer >=0.12.0`, make `typer` independent of `typer-slim`, include `typer` command in `typer` package. PR [#791](https://github.com/tiangolo/typer/pull/791) by [@tiangolo](https://github.com/tiangolo).
This fixes a problem that would break the `typer` installation directory when upgrading from `typer <0.12.0` to `typer >=0.12.0`, see issue [#790](https://github.com/tiangolo/typer/issues/790).
By installing the latest version (`0.12.1`) it fixes it, for any previous version, even if the installation directory was already broken by the previous upgrade.
### Internal
* 👷 Add cron to run test once a week on monday. PR [#783](https://github.com/tiangolo/typer/pull/783) by [@estebanx64](https://github.com/estebanx64).
## 0.12.0
In version `0.12.0`, the `typer` package depends on `typer-slim[standard]` which includes the default dependencies (instead of `typer[all]`) and `typer-cli` (that provides the `typer` command).
If you don't want the extra optional dependencies (`rich` and `shellingham`), you can install `typer-slim` instead.
You can also install `typer-slim[standard]`, which includes the default optional dependencies, but not the `typer` command.
In version `0.12.0` the `typer-cli` package only provides the `typer` command, but the code is still in the main code, so even without installing `typer-cli`, it can be called with `python -m typer`.
This approach of having `typer` depend on `typer-slim[standard]` instead of including the whole code and dependencies itself caused an issue when upgrading from `typer <0.12.0` to `typer >=0.12.0`, see issue [#790](https://github.com/tiangolo/typer/issues/790). This is fixed in version `0.12.1`.
### Features
* ✨ Add `typer-slim` package without extras, make `typer` include `typer-slim[default]` and integrate Typer CLI (`typer` command) into Typer. PR [#780](https://github.com/tiangolo/typer/pull/780) by [@tiangolo](https://github.com/tiangolo).

## 0.6.0
This release adds deep integrations with [Rich](https://rich.readthedocs.io/en/stable/). ✨
`rich` is an optional dependency, you can install it directly or it will be included when you install with:
```console
$ pip install "typer[all]"
```
If Rich is available, it will be used to show the content from `--help` options, validation errors, and even errors in your app (exception tracebacks).
There are new options to group commands, *CLI arguments*, and *CLI options*, support for [Rich Console Markup](https://rich.readthedocs.io/en/stable/markup.html), and more! 🎉

* Support for Rich Markup (different from Markdown) in docstrings, *CLI parameters* `help`, and `epilog` with the new parameter `typer.Typer(rich_markup_mode="rich")`, new docs: [Commands - Command Help - Rich Markdown and Markup](https://typer.tiangolo.com/tutorial/commands/help/#rich-markdown-and-markup).

## 0.3.0
* Add support for `help` parameter in *CLI arguments*:
* As `help` in *CLI arguments* is not supported by Click, there are two new internal classes (Click sub-classes) to support it:
* `typer.core.TyperArgument`
* `typer.core.TyperCommand`
* This includes a new auto-generated help text section `Arguments` for *CLI arguments*, showing defaults, required arguments, etc.
* It's also possible to disable it and keep the previous behavior, not showing automatic help for *CLI arguments* (Click's default) using the `hidden` parameter.
* Now `show_default` is `True` by default.
* And now `show_envvar` is `True` by default.
* So, default values and env vars are shown in the help text by default, without having to manually enable them, for both *CLI arguments* and *CLI options*.
* New docs:
* [CLI Arguments Intro](https://typer.tiangolo.com/tutorial/arguments/).
* [Optional CLI Arguments](https://typer.tiangolo.com/tutorial/arguments/optional/).
* [CLI Arguments with Default](https://typer.tiangolo.com/tutorial/arguments/default/).

* [CLI arguments with tuples](https://typer.tiangolo.com/tutorial/multiple-values/arguments-with-multiple-values/#cli-arguments-with-tuples).
