  • Backups created with Seedvault can be uploaded on your Nextcloud instance, an external USB drive or kept on your local storage.
• There is now an option on non-A/B devices to update the recovery image alongside the OS, just as the stock OS would!
  • To use this, either enable the option during the initial device setup or navigate to Settings -> System -> (Show More) Updater -> Three Dot Menu in the top right -> and check “Update recovery alongside OS”.
• Our music app, Eleven now has a more up-to-date UI and integrates nicely with all the new android features for music players such as seeking from the notification.

• (17.1 too) Trebuchet now supports icon packs.
• (17.1 too) ADB root was reworked to ensure compatibility with other 3rd party root solutions.

Generic Targets

Though we’ve had buildable generic targets since 2019, in an effort to make LineageOS more accessible to developers, and really anyone interested in giving LineageOS a try, we’ve documented how to use them in conjunction with the AndroidEmulator/Android Studio! This enables the average person to build and run LineageOS on their local PC.

Additionally, these same targets can now be used to build GSI’s in both mobile and Android TV configurations, making LineageOS more accessible than ever todevices using Google’sProject Treble. We won’t be providingofficial builds for these targets due to the fact the user-experience varies entirely based on how well the device manufacturer complied with Treble’srequirements, but feel free to go build them yourself and give it a shot!

Sensitive phone numbers

InChangelog 10 we introduced the feature that some sensitive phone numbers are automatically hidden from the call log.
For world suicide prevention day weasked you on Reddit about additional numbers for your countries.
LineageOS 18.1 now finally makes use of all that information and introduces a helpline contact list (just look at the 3-dot menu in the dialer to find it).In addition to quickly being able to find and call any of these numbers, we also show names, languages, websites, and categories for many of them.To improve upon that we want to ask you to have a look at theexisting listand let us know of any additional numbers or information for existing ones.

Addon.d-v3

For all the addon creators out there, addon.d now supports extra system partitions.This means that you can now backup and restore files in/vendor,/product, and/system_ext without any extra work.

For a reference addon.d script, you may refer to thisexample gist.For interface and implementation details, please refer to the documentation and the code inthe implementing commit.

Engineering Blog

We know it’s been a while since we posted on ourEngineering Blog, but contributors Aayush Gupta (theimpulson)and Nolen Johnson (npjohnson) recently posted a comprehensive piece on working with SELinux on Android! Just about everyone can benefit from givingit a read, it’s written in a way that both aspiring, and seasoned developers will learn something new. You can read ithere!

Deprecations

On the whole, we feel that the 18.1 branch has reached feature and stability parity with 17.1 and is ready for initial release.

LineageOS 16.0 builds stopped on February 15th, 2021, to allow space on our infrastructure to begin testing LineageOS 18.1.

LineageOS 18.1 will launch building for a fairly wide selection of devices, with additional devices to come as they are marked as bothCharter compliant and ready for builds by their maintainer.

Upgrading to LineageOS 18.1

To upgrade, please follow the upgrade guide for your device foundhere.

If you’re coming from an unofficial build, you need to follow the good ole’ install guide for your device, just like anyone else looking toinstall LineageOS for the first time. These can be foundhere.

Please note that if you’re currently on an official build, youDO NOT need to wipe your device, unless your device’s wiki page specifically dictates otherwise, as is needed for some devices with massivechanges, such as a repartition.

Importance of the Wiki

Though theLineageOS Wiki has existed since our inception, we’d like to take this time to remind users tofollow instructions on their device’s respectiveWiki Page as given the complexity introduced AOSPchanges like System-As-Root, A/B Partition Scheme, Dynamic Partitions, and most recentlyVirtual A/B found on the Pixel 5 and other devices launching with Android 11, the instructionsmany of you are used to following from memory are either no longer valid or are missing very critical steps. As of 16.0, maintainers havebeen expected to run through the full instructions, and verify they work on their devices. The LineageOS Wiki was recently further extended, andmaintainers were given significantly more options to customize their device’s individual installation, update, and upgrade instructions.

Developers, Developers, Developers

Or, in this case, maintainers, maintainers, maintainers. We want your device submissions!

If you’re a developer and would like to submit your device for officials, it’s easier than ever. Just follow the instructionshere.

The above also applies to people looking to bring back devices that were at one point official, but no longer supported - seriously - even if it’s not yet completely compliant, submit it! Maybe we can help you review it.

After you submit, within generally a few weeks, but in most cases a week, you’ll receive some feedback on your device submission, and if it’s up to par, invited to our communicationsinstances, and your device forked to LineageOS’s official repos.

Don’t have the knowledge to maintain a device, but want to contribute to the platform? We have lots of other thing you can contribute to:for instance our apps suite is always looking for new people to help improve them, or you can contribute to the wiki addingmore useful information & documentation.Gerrit is always open forsubmissions! Once you’ve contributed a few things, send an email to devrel(at)lineageos.org detailing them, and we’ll getyou in the loop.

Translations

Bilingual? Trilingual? Anything-lingual?

If you think you can help translate LineageOS to a different language, jump over toCrowdin and have a go!If your language is not supported natively in Android, reach us out on Crowdin and we’ll take the necessarysteps to include your language.For instance, LineageOS is the first Android custom distribution that has complete supportfor the Welsh (Cymraeg) language thanks to its community of translators.

Please, contribute to translations only if you are reasonably literate in the target language;poor translations waste both our time and yours.
