Briefcase

Features

* Support for less common environments, such as Linux on ARM, has been improved. Error messages for unsupported platforms are now more accurate. (1360)
* Tool verification for Java, Android SDK, and WiX have been improved to provide more informative errors and debug logging. (1382)
* A super verbose logging mode was added (enabled using `-vv`). This turns on all Briefcase internal logging, but also enables verbose logging for all the third-party tools that Briefcase invokes. (1384)
* Briefcase now uses Android SDK Command-Line Tools v9.0. If an externally-managed Android SDK is being used, it must provide this version of Command-Line Tools. Use the SDK Manager in Android Studio to ensure it is installed. (1397)
* Support for OpenSuSE Linux distributions was added. (1416)
* iOS apps are no longer rejected by the iOS App Store for packaging reasons. (1439)
* The Java JDK version was upgraded to 17.0.8.1+1. (1462)
* macOS apps can now be configured to produce single platform binaries, or binaries that will work on both x86_64 and ARM64. (1482)


Bugfixes

* Build warnings caused by bugs in Xcode that can be safely ignored are now filtered out of visible output. (377)
* The run command now ensures Android logging is shown when the datetime on the device is different from the host machine. (1146)
* Briefcase will detect if you attempt to launch an Android app on a device whose OS doesn't meet minimum version requirements. (1157)
* macOS apps are now guaranteed to be universal binaries, even when dependencies only provide single-architecture binary wheels. (1217)
* The ability to build AppImages in Docker on macOS was restored. (1352)
* Error reporting has been improved when the target Docker image name is invalid. (1368)
* Creating Debian packages no longer fails due to a permission error for certain `umask` values (such as `0077`). (1369)
* Inside of Docker containers, the Briefcase data directory is now mounted at `/briefcase` instead of `/home/brutus/.cache/briefcase`. (1374)
* The console output from invoking Python via a subprocess call is now properly decoded as UTF-8. (1407)
* The command line arguments used to configure the Python environment for `briefcase dev` no longer leak into the runtime environment on macOS. (1413)


Backward Incompatible Changes

* AppImage packaging requires a recent release of LinuxDeploy to continue creating AppImages. Run `briefcase upgrade linuxdeploy` to install the latest version. (1361)
* The size of iOS splash images have changed. iOS apps should now provide 800px, 1600px and 2400px images (previously, this as 1024px, 2048px and 3072px). This is because iOS 14 added a hard limit on the size of image resources. (1371)
* Support for AppImage has been reduced to "best effort". We will maintain unit test coverage for the AppImage backend, but we no longer build AppImages as part of our release process. We will accept bug reports related to AppImage support, and we will merge PRs that address AppImage support, but the core team no longer considers addressing AppImage bugs a priority, and discourages the use of AppImage for new projects. (1449)


Documentation

* Documentation on the process of retrieving certificate identities on macOS and Windows was improved. (1473)

Features

* Windows apps can now be packaged as simple ZIP files. (457)
* An Android SDK specified in `ANDROID_HOME` is respected now and will take precedence over the setting of `ANDROID_SDK_ROOT`. (463)
* Android support was upgraded to use Java 17 for builds. (1065)
* On Linux, Docker Desktop and rootless Docker are now supported. (1083)
* The company/author name in the installation path for Windows MSI installers is now optional. (1199)
* macOS code signing is now multi-threaded (and therefore much faster!) (1201)
* Briefcase will now honor PEP-621 project fields where they map to Briefcase configuration items. (1203)

Bugfixes

* XML compatibility warnings generated by the Android build have been cleaned up. (827)
* Non ASCII characters provided in the `briefcase new` wizard are quoted before being put into `pyproject.toml`. (1011)
* Requests to the web server are now recorded in the log file. (1090)
* An "Invalid Keystore format" error is no longer raised when signing an app if the local Android keystore was generated with a recent version of Java. (1112)
* Content before a closing square bracket (`]`) or `.so)` is no longer stripped by the macOS and iOS log filter. (1179)
* The option to run Linux system packages through Docker was removed. (1207)
* Error handling for incomplete or corrupted Github clones of templates has been improved. (1210)
* Application/Bundle IDs are normalized to replace underscores with dashes when possible (1234)
* Filenames and directories in RPM package definitions are quoted in order to include filenames that include white space. (1236)
* Briefcase will no longer display progress bars if the `FORCE_COLOR` environment variable is set. (1267)
* When creating a new Briefcase project, the header line in `pyproject.toml` now contains the version of Briefcase instead of "Unknown". (1276)
* Android logs no longer include timestamp and PID, making them easier to read on narrow screens. (1286)
* An warning is no longer logged if the Java identified by macOS is not usable by Briefcase. (1305)
* Incompatibilities with Cookiecutter 2.2.0 have been resolved. (1347)

Backward Incompatible Changes

* Names matching modules in the Python standard library, and `main`, can no longer be used as an application name. (853)
* The `--no-sign` option for packaging was removed. Briefcase will now prompt for a signing identity during packaging, falling back to adhoc/no signing as a default where possible. (865)
* The version of OpenJDK for Java was updated from 8 to 17. Any Android apps generated on previous versions of Briefcase must be re-generated by running `briefcase create android gradle`. If customizations were made to files within the generated app, they will need to be manually re-applied after re-running the create command. (1065)
* Flatpak apps no longer default to using the Freedesktop runtime and SDK version 21.08 when a runtime is not specified. Instead, the runtime now must be explicitly defined in the [application configuration](https://briefcase.readthedocs.io/en/latest/reference/platforms/linux/flatpak.html#application-configuration). (1272)


Documentation

* All code blocks were updated to add a button to copy the relevant contents on to the user's clipboard. (1213)
* The limitations of using WebKit2 in AppImage were documented. (1322)

Bugfixes

* When commands produce output that cannot be decoded to Unicode, Briefcase now writes the bytes as hex instead of truncating output or canceling the command altogether. (1141)
* When `JAVA_HOME` contains a path to a file instead of a directory, Briefcase will now warn the user and install an isolated copy of Java instead of logging a `NotADirectoryError`. (1144)
* If the Docker `buildx` plugin is not installed, users are now directed by Briefcase to install it instead of Docker failing to build the image. (1153)

* Resources that require variants will now use the variant name as part of the filename by default. (989)
* `briefcase open linux appimage` now starts a shell session in the Docker context, rather than opening the project folder. (991)
* Web project configuration has been updated to reflect recent changes to PyScript. (1004)

Bugfixes

* Console output of Windows apps is now captured in the Briefcase log. (787)
* Android emulators configured with `_no_skin` will no longer generate a warning. (882)
* Briefcase now exits normally when CTRL-C is sent while tailing logs for the App when using `briefcase run`. (904)
* Backslashes and double quotes are now safe to be used for formal name and description (905)
* The console output for Windows batch scripts in now captured in the Briefcase log. (917)
* When using the Windows Store version of Python, Briefcase now ensures the cache directory is created in `%LOCALAPPDATA%` instead of the sandboxed location enforced for Windows Store apps. (922)
