ADOBE AIR SDK RELEASE NOTES

1 Release Overview
Release 51.1.2.1 is a new feature release of the AIR 51.1 version, with the required updates for iOS
18 and a number of other minor feature improvements. No changes have been made to the
ActionScript APIs or versioning, or the XML descriptor file format, so the SWF version for this
continues to be 51 and the namespace continues at “51.1”.
1.1 Key changes
The build environment has been updated for for the macOS/iOS platforms, with the latest Apple SDKs
and build tools being used for these. This also means the ‘stub’ files include the new iOS/tvOS library
files so that applications/ANEs could access these APIs, although our recommendation is to develop
these applications on macOS where we can use the Apple linker and the official SDKs.
Two key changes to the iOS builds are to fix a problem in the AOT compiler with numerical operations
that can happen when a ‘float’ type is also used; and to ensure that Basic Authentication is working
properly when used in conjunction with self-signed certificates in HTTPS connections.
A number of updates have been provided on Android, with some focus on stability where applications
are set up to use the runtime in the ‘background’ thread.
Further changes are made to ADT to remove some of the confusing warning messages (which are
instead only output to the log file/troubleshooting connection), introducing the ability to generate a
universal APK file from an AAB bundle, and to be able to code-sign using “provider” class and
argument values, to match the jarsigner behaviour and support hardware tokens.
1.2 Deployment
To obtain the release, it is recommended that developers install the AIR SDK Manager. Whilst the
monolithic zip files will still be available from the https://airsdk.harman.com
website, this may be
updated less frequently in the future with only major releases. The goal is for the AIR SDK Manager to
help us publish minor updates/fixes with a quicker cadence without resulting in a large amount of
effort and data downloads.
The AIR SDK Manager is now available from the https://airsdk.dev website, as part of the “getting
started” instructions, or directly from github at: https://github.com/airsdk/airsdkmanager-releases
1.3 Limitations
For macOS users on 10.15+, the SDK may not work properly unless the quarantine setting is
removed from the SDK: $ xattr -d -r com.apple.quarantine /path/to/SDK
Please note that there is no longer support for 32-bit IPA files, all IPAs will use just 64-bit binaries now
so older iPhones/iPads may not be supported.
Android development should now be performed with an installation of Android Studio and the SDK
and build tools, so that the new build mechanism (using Gradle and the Android Gradle Plug-in) can
use the same set-up as Android Studio.
Linux runtimes are built using Ubuntu 16 for x86_64 variants in order to provide maximum
compatibility; however for arm64, the build environment uses Ubuntu 22 which then restricts usage to
similar versions of Linux (i.e. that have glibc version 2.34 or later).
