Google's Firebase Cloud Messaging (FCM) does not work with decentralized networks. According to its logic, there should be only one account on FCM, which is hardwired into the application, and the server should sign messages with the private key of this account. Naturally, this cuts off the possibility of different people installing several servers interacting with one application, because the private key is to be published, and spam will pour into the application.

Therefore, I had to create a relay (fcm.moera.org) that forwards messages from different nodes to FCM. When a user enters the application for the first time being logged in, the application forwards the client's FCM ID to its home node, which sends it to the FCM relay. Knowing this identifier confirms that the node has the right to send notifications to the client.

• Implemented reliable delivery and display of notifications via the Google Firebird Cloud Messaging (FCM) service. The old approach for delivering notifications stopped working due to restrictions on background services introduced in new versions of Android. The notification design has also been improved.
• Show notifications and internal application messages in the language selected by the user.
• Opening Moera links in the application. The new domain moera.page is supported.
• No longer asking for permission to access images stored on the device. Instead, using Android's built-in image selection component (a Google Play requirement).
• Improved reliability when switching between Wi-Fi and mobile networks.

• Universal URLs. These new URLs of Moera pages use a central redirector at moera.page host and include a node name. Read the details in the documentation.

• Browser add-on support removed.
• Node now requires Java 17 for running.
• Developers' naming server is now used in development environments.

Browser extension was a part of Moera since the very beginning. It has several goals, such as:

1. Automatically loading Moera client when visiting a website that supports Moera. Since the network is decentralized, Moera can be installed on any website and the browser extension helps to detect it.
2. It always loads the client that the user prefers.
3. Showing a direct link to the website in the address bar of the browser, which can be simply copied from there instead of choosing "Copy link" from the menu of a post or comment.
4. Allows to get rid of the single point of failure, which is the website that redirects the user to the Moera client they choose.

Link previews. When you insert a link into the text of a post or comment, a special panel appears below it: an image, a title, and a brief description of what the link leads to. In Moera, a post/comment can have several links with previews. A post/comment can have both attached images and link previews at the same time. You can choose which links to show previews for (using the "Links" button under the editor), delete previews (click the cross in the upper right corner) and edit the preview text (click the pencil there).

• No page refresh when the device changes orientation.
• No page refresh when scrolling dialog contents or notifications.
• Allow to exit from image selection without selecting anything (thanks to Daria-Ch for reporting).
• No crash when clicking any URI.
• Fixed cropping of round avatars in notifications.

Images in posts and comments. Now you can attach images to posts and comments and even insert them into the text. Number of images per post/comment is not limited. For an inserted image, you can choose its size and alignment, including text wrapping. It is possible to add three types of captions to images: (1) a caption under the image when it is inserted into text; (2) a tooltip shown when the image is hovered by the cursor; (3) a description, that is shown when viewing the enlarged image (see below).

Images may be uploaded from computer/mobile device ("Upload images" button) or copied from the Internet ("Copy image" button).

Avatars. Users now have avatars. The built-in editor allows to create an avatar from any image, to crop and rotate it, if needed. You can choose an avatar shape - round or square. You can create several avatars and change them when writing a post or a comment. You can also reorder avatars in the list. And if you do not like that avatars may be of different shapes, they may be forced in client settings to be all round or all square. Clicking on an avatar opens the user's profile.

Comment drafts. Like when creating or editing a post, drafts are now saved automatically when creating or editing a comment. You can leave an unfinished comment behind and it will appear again in the comment editor, when you open the same thread.
