+# Release Notes
+
+## 2023.05.01
+
+### Features
+
+-   Added the `xterm` attribute to `py-config`. When set to `True` or `xterm`, an (output-only) [xterm.js](http://xtermjs.org/) terminal will be used in place of the default py-terminal.
+-   The default version of Pyodide is now `0.23.2`. See the [Pyodide Changelog](https://pyodide.org/en/stable/project/changelog.html#version-0-23-2) for a detailed list of changes.
+-   Added the `@when` decorator for attaching Python functions as event handlers
+-   The `py-mount` attribute on HTML elements has been deprecated, and will be removed in a future release.
+
+#### Runtime py- attributes
+
+-   Added logic to react to `py-*` attributes changes, removal, `py-*` attributes added to already live nodes but also `py-*` attributes added or defined via injected nodes (either appended or via `innerHTML` operations). ([#1435](https://github.com/pyscript/pyscript/pull/1435))
+
+#### <script type="py">
+
+-   Added the ability to optionally use `<script type="py">`, `<script type="pyscript">` or `<script type="py-script">` instead of a `<py-script>` custom element, in order to tackle cases where the content of the `<py-script>` tag, inevitably parsed by browsers, could accidentally contain _HTML_ able to break the surrounding page layout. ([#1396](https://github.com/pyscript/pyscript/pull/1396))
+
+#### &lt;py-terminal&gt;
+
+-   Added a `docked` field and attribute for the `<py-terminal>` custom element, enabled by default when the terminal is in `auto` mode, and able to dock the terminal at the bottom of the page with auto scroll on new code execution.
+
+#### &lt;py-script&gt;
+
+-   Restored the `output` attribute of `py-script` tags to route `sys.stdout` to a DOM element with the given ID. ([#1063](https://github.com/pyscript/pyscript/pull/1063))
+-   Added a `stderr` attribute of `py-script` tags to route `sys.stderr` to a DOM element with the given ID. ([#1063](https://github.com/pyscript/pyscript/pull/1063))
+
+#### &lt;py-repl&gt;
+
+-   The `output` attribute of `py-repl` tags now specifies the id of the DOM element that `sys.stdout`, `sys.stderr`, and the results of a REPL execution are written to. It no longer affects the location of calls to `display()`
+-   Added a `stderr` attribute of `py-repl` tags to route `sys.stderr` to a DOM element with the given ID. ([#1106](https://github.com/pyscript/pyscript/pull/1106))
+-   Resored the `output-mode` attribute of `py-repl` tags. If `output-mode` == 'append', the DOM element where output is printed is _not_ cleared before writing new results.
+-   Load code from the attribute src of py-repl and preload it into the corresponding py-repl tag by use the attribute `str` in your `py-repl` tag([#1292](https://github.com/pyscript/pyscript/pull/1292))
+-   &lt;py-repl&gt; elements now have a `getPySrc()` method, which returns the code inside the REPL as a string.([#1516](https://github.com/pyscript/pyscript/pull/1292))
+
+#### Plugins
+
+-   Plugins may now implement the `beforePyReplExec()` and `afterPyReplExec()` hooks, which are called immediately before and after code in a `py-repl` tag is executed. ([#1106](https://github.com/pyscript/pyscript/pull/1106))
+
+#### Web worker support
+
+-   introduced the new experimental `execution_thread` config option: if you set `execution_thread = "worker"`, the python interpreter runs inside a web worker
+-   worker support is still **very** experimental: not everything works, use it at your own risk
+
+### Bug fixes
+
+-   Fixes [#1280](https://github.com/pyscript/pyscript/issues/1280), which describes the errors on the PyRepl tests related to having auto-gen tags that shouldn't be there.
+
+### Enhancements
+
+-   Py-REPL tests now run on both osx and non osx OSs
+-   migrated from _rollup_ to _esbuild_ to create artifacts
+-   updated `@codemirror` dependency to its latest
+
+### Docs
+
+-   Add docs for event handlers
+
+## 2023.03.1
+
+### Features
+
+### Bug fixes
+
+-   Fixed an issue where `pyscript` would not be available when using the minified version of PyScript. ([#1054](https://github.com/pyscript/pyscript/pull/1054))
+-   Fixed missing closing tag when rendering an image with `display`. ([#1058](https://github.com/pyscript/pyscript/pull/1058))
+-   Fixed a bug where Python plugins methods were being executed twice. ([#1064](https://github.com/pyscript/pyscript/pull/1064))
+
+### Enhancements
+
+-   When adding a `py-` attribute to an element but didn't added an `id` attribute, PyScript will now generate a random ID for the element instead of throwing an error which caused the splash screen to not shutdown. ([#1122](https://github.com/pyscript/pyscript/pull/1122))
+-   You can now disable the splashscreen by setting `enabled = false` in your `py-config` under the `[splashscreen]` configuration section. ([#1138](https://github.com/pyscript/pyscript/pull/1138))
+
+### Documentation
+
+-   Fixed 'Direct usage of document is deprecated' warning in the getting started guide. ([#1052](https://github.com/pyscript/pyscript/pull/1052))
+-   Added reference documentation for the `py-splashscreen` plugin ([#1138](https://github.com/pyscript/pyscript/pull/1138))
+-   Adds doc for installing tests ([#1156](https://github.com/pyscript/pyscript/pull/1156))
+-   Adds docs for custom Pyscript attributes (`py-*`) that allow you to add event listeners to an element ([#1125](https://github.com/pyscript/pyscript/pull/1125))
+
+### Deprecations and Removals
+
+-   The py-config `runtimes` to specify an interpreter has been deprecated. The `interpreters` config should be used instead. ([#1082](https://github.com/pyscript/pyscript/pull/1082))
+-   The attributes `pys-onClick` and `pys-onKeyDown` have been deprecated, but the warning was only shown in the console. An alert banner will now be shown on the page if the attributes are used. They will be removed in the next release. ([#1084](https://github.com/pyscript/pyscript/pull/1084))
+-   The pyscript elements `py-button`, `py-inputbox`, `py-box` and `py-title` have now completed their deprecation cycle and have been removed. ([#1084](https://github.com/pyscript/pyscript/pull/1084))
+-   The attributes `pys-onClick` and `pys-onKeyDown` have been removed. Use `py-click` and `py-keydown` instead ([#1361](https://github.com/pyscript/pyscript/pull/1361))

 # PyScript
 
-## PyScript is an open source platform for Python in the browser.
+## What is PyScript
 
-Using PyScript is as simple as:
+### Summary
+
+PyScript is a framework that allows users to create rich Python applications in the browser using HTML's interface and the power of [Pyodide](https://pyodide.org/en/stable/), [MicroPython](https://micropython.org/) and [WASM](https://webassembly.org/), and modern web technologies.
+
+To get started see the [getting started tutorial](https://pyscript.github.io/docs/latest/beginning-pyscript/).
+
+For examples see [here](examples).
+
+### Longer Version
+
+PyScript is a meta project that aims to combine multiple open technologies into a framework that allows users to create sophisticated browser applications with Python. It integrates seamlessly with the way the DOM works in the browser and allows users to add Python logic in a way that feels natural both to web and Python developers.
+
+## Try PyScript
+
+To try PyScript, import the appropriate pyscript files into the `<head>` tag of your html page:
 
 ```html
-<!doctype html>
+<head>
-<html lang="en">
+    <link
-    <head>
+        rel="stylesheet"
-        <meta charset="utf-8" />
+        href="https://pyscript.net/releases/2023.11.1/core.css"
-        <meta name="viewport" content="width=device-width,initial-scale=1" />
+    />
-        <title>PyScript!</title>
+    <script
-        <link
+        type="module"
-            rel="stylesheet"
+        src="https://pyscript.net/releases/2023.11.1/core.js"
-            href="https://pyscript.net/releases/2025.10.2/core.css"
+    ></script>
-        />
+</head>
-        <script
+<body>
-            type="module"
+    <script type="py" terminal>
-            src="https://pyscript.net/releases/2025.10.2/core.js"
+        from pyscript import display
-        ></script>
+        display("Hello World!") # this goes to the DOM
-    </head>
+        print("Hello terminal") # this goes to the terminal
-    <body>
+    </script>
-        <!-- type mpy (MicroPython) or py (Pyodide) to run some Python -->
+</body>
-        <script type="mpy" terminal>
-            print("Hello, world!")
-        </script>
-    </body>
-</html>
 ```
 
-PyScript enables the creation of rich Python applications in the browser using
+You can then use PyScript components in your html page. PyScript currently offers various ways of running Python code:
-[Pyodide](https://pyodide.org/en/stable/) (a version of
-[CPython](https://python.org/)), [MicroPython](https://micropython.org/),
-[WASM](https://webassembly.org/), and modern web technologies. It means Python
-now runs anywhere a browser runs: desktop, laptop, mobile, tablet, or any other
-browser enabled device.
 
-To start building, read the
+-   `<script type="py">`: can be used to define python code that is executable within the web page.
-[Beginning PyScript tutorial](https://docs.pyscript.net/latest/beginning-pyscript/).
+-   `<script type="py" src="hello.py">`: same as above, but the python source is fetched from the given URL.
+-   `<script type="py" terminal>`: same as above, but also creates a terminal where to display stdout and stderr (e.g., the output of `print()`); `input()` does not work.
+-   `<script type="py" terminal worker>`: run Python inside a web worker: the terminal if fully functional and `input()` works.
+-   `<py-script>`: same as `<script type="py">`, but it is not recommended because if the code contains HTML tags, they could be parsed wrongly.
+-   `<script type="mpy">`: same as above but use MicroPython instead of Python.

+# Troubleshooting

+This page is meant for troubleshooting common problems with PyScript.
+
+## Table of contents:

+-   [Make Setup](#make-setup)
+
+## Make setup
+
+A lot of problems related to `make setup` are related to node and npm being outdated. Once npm and node are updated, `make setup` should work. You can follow the steps on the [npm documentation](https://docs.npmjs.com/try-the-latest-stable-version-of-npm) to update npm (the update command for Linux should work for Mac as well). Once npm has been updated you can continue to the instructions to update node below.
+
+To update Node run the following commands in order (Most likely you'll be prompted for your user password, this is normal):
+
+```
+sudo npm cache clean -f
+sudo npm install -g n
+sudo n stable
+```

-# @pyscript/bridge
-
-Import Python utilities directly in JS
-
-```js
-// main thread
-const { ffi: { func_a, func_b } } = await import('./test.js');
-
-// test.js
-import bridge from 'https://esm.run/@pyscript/bridge';
-export const ffi = bridge(import.meta.url, { type: 'mpy', worker: false });
-
-// test.py
-def func_a(value):
-    print(f"hello {value}")
-
-def func_b():
-    import sys
-    return sys.version
-```
-
-### Options
-
-  * **pyscript**: the release version to automatically import if not already available on the page. If no version is provided the *developers' channel* version will be used instead (for developers' purposes only).
-  * **type**: `py` by default to bootstrap *Pyodide*.
-  * **worker**: `true` by default to bootstrap in a *Web Worker*.
-  * **config**: either a *string* or a PyScript compatible config *JS literal* to make it possible to bootstrap files and whatnot. If specified, the `worker` becomes implicitly `true` to avoid multiple configs conflicting on the main thread.
-  * **env**: to share the same environment across multiple modules loaded at different times.
-
-
-## Tests
-
-Run `npx mini-coi .` within this folder to then reach out `http://localhost:8080/test/` that will show:
-
-```
-PyScript Bridge
-------------------
-no config
-```
-
-The [test.js](./test/test.js) files uses the following defaults:
-
-  * `pyscript` as `"2025.8.1"`
-  * `type` as `"mpy"`
-  * `worker` as `false`
-  * `config` as `undefined`
-  * `env` as `undefined`
-
-To test any variant use query string parameters so that `?type=py` will use `py` instead, `worker` will use a worker and `config` will use a basic *config* that brings in another file from the same folder which exposes the version.
-
-To recap: `http://localhost:8080/test/?type=py&worker&config` will show this instead:
-
-```
-PyScript Bridge
-------------------
-3.12.7 (main, May 15 2025, 18:47:24) ...
-```
-
-Please note when a *config* is used, the `worker` attribute is always `true`.

-# @pyscript/core

-PyScript brings two Python interpreters to the browser:
-
--   [MicroPython](https://micropython.org/) - a lean and efficient implementation
-    of the Python 3 programming language that includes a small subset of the
-    Python standard library and is optimised to run on microcontrollers and in
-    constrained environments (like the browser).
--   [Pyodide](https://pyodide.org)) - a port of all CPython to WebAssembly.
-
-These interpreters are compiled to [WebAssembly](https://webassembly.org/)
-(shortened to WASM). The browser provides a secure WASM computing sandbox. Both
-interpreters are compiled to web assembly with
-[Emscripten](https://emscripten.org/). PyScript core maintainers work closely
-with the core maintainers of both MicroPython and Pyodide (and CPython). We
-work hard to ensure PyScript works efficiently in browsers on all platforms:
-desktop, mobile, or elsewhere.
-
-Our technical documentation for using this project can be
-[found here](https://docs.pyscript.net/).
-
-PyScript sits on two further projects (both written in JavaScript):
-
-1. [polyscript](https://github.com/pyscript/polyscript/#readme) - used to
-   bootstrap WASM compiled interpreters in a browser.
-2. [coincident](https://github.com/WebReflection/coincident) - used to simplify
-   worker based tasks.
-
-PyScript itself is mostly written in JavaScript. The test suite for JavaScript
-is in two parts: automated tests run in [playwright](https://playwright.dev/),
-and manual tests you have to run in a browser and check yourself. PyScript also
-has a plugin system so third parties can extend its capabilities with
-JavaScript. Our built-in core plugins can be found in the `src/plugins`
-directory. We describe how to write third party plugins in our
-[developer documentation](https://docs.pyscript.net/latest/user-guide/plugins/).
-
-We provide a `pyscript` namespace containing Python modules for common browser
-based APIs and features (i.e. you can `import pyscript` in Python code running
-inside PyScript, to access these features). The Python code for the `pyscript`
-namespace is in `src/stdlib/pyscript` with the associated test suite in
-`tests/python`. The tests use the browser friendly
-[uPyTest](https://github.com/ntoll/upytest) test framework for checking Python
-code running _within_ PyScript. All the Python tests are run in each each
-available interpreter in both the main thread and a web worker (i.e. the
-test suite is run four times, accounting for each combination of interpreter
-and main/worker context).
-
-When you create a local build all the automated tests (JavaScript and Python)
-are run.
-
-## Developer Guide
-
-Full instructions for setting up a working development environment, how to
-build PyScript and how to test it can be
-[found in our official docs](https://docs.pyscript.net/latest/developers/).
-
-The short version is:
-
--   Ensure you have Python, node and npm installed.
--   Create a Python virtual environment.
--   In the root of this repository `make setup`.
--   `make build` to build PyScript.
--   As dependencies change over time, `make update` to keep in sync.
-
-To start using the locally built version of PyScript, you'll need an HTML
-page something like this (note the relative paths to assets in the `dist`
-directory, in the `<head>` of the document):
-

-Once set up, you should be able to run the most common activities via the
-`make` command:
-

-$ make
-
-There is no default Makefile target right now. Try:
-
-make setup - check your environment and install the dependencies.
-make update - update dependencies.
-make clean - clean up auto-generated assets.
-make build - build PyScript.
-make precommit-check - run the precommit checks (run eslint).
-make test - run all automated tests in playwright.
-make fmt - format the code.
-make fmt-check - check the code formatting.
-```
-
-## Artifacts
-
-There are two main artifacts in this project:
-
--   **stdlib** and its content: `src/stdlib/pyscript.js` exposes, as a
-    JavaScript object literal, all the _Python_ content within the folder
-    (recursively).
--   **plugins** and its content: `src/plugins.js` exposes all available
-    _dynamic imports_, and is able to instrument the bundler to create files
-    apart from the `_dist/_` folder, so that by default _core_ remains as small
-    as possible.
-
-Accordingly, whenever a file contains this warning at its first line, **please
-do not change such file directly before submitting a merge request**, as that
-file will be overwritten at the next `npm run build` command, either here or
-in _CI_:
-
-```js
-// ⚠️ This file is an artifact: DO NOT MODIFY
-```
-
-## Plugins
-
-While community or third party plugins don't need to be part of this repository
-and can be added just importing `@pyscript/core` as module, there are a few
-plugins that we would like to make available by default and these are
-considered _core plugins_.
-
-To add a _core plugin_ to this project define the plugin entry-point and name
-in the `src/plugins` folder (see the `error.js` example) and create, if
-necessary, a folder with the same name where extra files or dependencies can be
-added.
-
-The _build_ command will include plugins by name as artifacts so that the
-bundler can create ad-hoc files within the `dist/` folder.
-
-## Python
-
-The `pyscript` package available in _Python_ lives in the folder
-`src/stdlib/pyscript/`.
-
-All _Python_ files will be embedded automatically whenever `npm run build`
-happens and reflected into the `src/stdlib/pyscript.js` file.
-
-Its _core_ responsibility is to ensure those files will be available through
-the filesystem in either the _main_ thread, or any _worker_.
-
-## Release
-
-To cut a new release of PyScript simply
-[add a new release](https://github.com/pyscript/pyscript/releases) while
-remembering to write a comprehensive changelog. A
-[GitHub action](https://github.com/pyscript/pyscript/blob/main/.github/workflows/publish-release.yml)
-will kick in and ensure the release is described and deployed to a URL with the
-pattern: https://pyscript.net/releases/YYYY.M.v/ (year/month/version - as per
-our [CalVer](https://calver.org/) versioning scheme).
-
-Then, the following three separate repositories need updating:
-
--   [Documentation](https://github.com/pyscript/docs) - Change the `version.json`
-    file in the root of the directory and then `node version-update.js`.
--   [Homepage](https://github.com/pyscript/pyscript.net) - Ensure the version
-    referenced in `index.html` is the latest version.
--   [PSDC](https://pyscript.com) - Use discord or Anaconda Slack (if you work at
-    Anaconda) to let the PSDC team know there's a new version, so they can update
-    their project templates.

-There are three aspects to our test suite. These are reflected in the layout of
-the test directory:
-
-1. `python` - contains the Python based test suite to exercise Python code
-   **within** PyScript. These tests are run four differeng ways to ensure all
-   combination of MicroPython/Pyodide and main thread/worker contexts are
-   checked.
-2. `javascript` - contains JavaScript tests to exercise PyScript _itself_, in
-   the browser.
-3. `manual` - contains tests to run manually in a browser, due to the complex
-   nature of the tests.
-
-We use [Playwright](https://playwright.dev/) to automate the running of the
-Python and JavaScript test suites. We use
-[uPyTest](https://github.com/ntoll/upytest) as a test framework for the Python
-test suite. uPyTest is a "PyTest inspired" framework for running tests in the
-browser on both MicroPython and Pyodide.
-
-The automated (Playwright) tests are specified in the `integration.spec.js`
-file in this directory.
-
-All automatic tests live in either the `python` or `javascript` folders. All
-the tests in these folder are run by CI or locally run by `make test` in the
-root of this project. Alternatively, run `npm run test:integration` in the
-PyScript source directory.
-
-Similarly, some tests can only be run manually (due to their nature or
-underlying complexity). These are in the `manual` directory and are in the form
-of separate directories (each containing an `index.html`) or individual `*.html`
-files to which you point your browser. Each separate test may exercise
-JavaScript or Python code (or both), and the context for each separate test is
-kept carefully isolated.
-
-Some rules of thumb:
-
-* We don't test upstream projects: we assume they have their own test suites,
-  and if we find bugs, we file an issue upstream with an example of how to
-  recreate the problem.
-* We don't test browser functionality, we just have to trust that browsers work
-  as advertised. Once again, if we find an issue, we report upstream.
-* All test cases should include commentary describing the **intent** and
-  context of the test.
-* Tests in Python use [uPyTest](https://github.com/ntoll/upytest) (see the
-  README for documentation), an "inspired by PyTest" test framework that works
-  with both MicroPython and Pyodide in the browser. This means that all
-  Python tests should work with both interpreters.
-* Tests in JavaScript... (Andrea to explain). ;-)
