GROUP CHATS Talk with up to 50 people at once, end-to-end encrypted like every one-to-one chat. Tap the compose button, then New group, pick contacts and give the group a name, a description and a photo. • Type @ to mention someone. A mention of you is highlighted, and the @ on the group's tile takes you straight to it. • Members who are not your contacts show with ~ before their name. A name is whatever its owner typed, so check the Keylane tag before you trust it. • Admins add and remove people, change the name, description and photo, set Auto-delete for everyone, and can delete any message. • Block or report any member from group info. • Leaving or being removed deletes the group and its media from your phone. Save anything you want to keep to your Secure Notebook first. DELETE FOR BOTH SIDES, NOW FOR THE WHOLE CHAT Delete for both sides now covers the contact's messages too, not just yours. Each phone deletes the messages by itself, so it holds even when the other phone is off. Turning it on also applies to the messages already in the chat, and photos and files go with them. ALSO NEW • Save several photos or files to your Secure Notebook at once: in shared media, press and hold one, tap the others, then tap send and Save to notebook • Group info shows the group's shared media • iPad: a better photo cropper and invite screen • Fixed a crash when deleting on the letters & symbols PIN keyboard • Fixes and reliability improvements Group chats, and delete for both sides on the contact's messages, need Keylane 1.0.5 or newer on every phone.

KEYLANE FOR IPAD A layout made for the big screen: your chats and the open conversation side by side, Contact Info next to the chat, keyboard shortcuts, landscape and Split View. SWIPE THROUGH PHOTOS AND VIDEOS Open a photo or a video from a chat, a note or your media, then swipe left or right for the next one. No need to close it first. Pinch or double-tap to zoom. REACTIONS Press and hold a message and tap favorite emoji or + for any other emoji. One reaction each, and reactions never send a notification. EDIT A SENT MESSAGE Fix a typo for up to an hour after sending. Text messages and photo or file captions can be edited, and the contact sees the new text marked "edited". SETTINGS FOR EACH CHAT Give any chat its own auto-delete time (now also 1, 3, 6 or 12 hours), media download, delete for both sides and text size. AUTO-DELETE YOU CAN SEE The chat header shows how long messages are kept, a small timer marks messages about to go, and the chat tells you when a contact turns on delete for both sides. ALSO NEW • Show typed characters: turn it off in Privacy & Security and the letters & symbols PIN keyboard no longer shows what you type • Saving a photo or file tells you where it went • The chat text size now applies to the message box too • What's new, inside the app: under the version number in Settings • Fixes and reliability improvements Reactions and edits need Keylane 1.0.4 or newer on both phones.

Open Beta Update 1.0.3: security fixes from our internal review of the app, a guided first run, and many improvements requested by beta testers. NEW • Step-by-step setup: choose your name, photo and PIN, with a clear explanation of what the PIN protects. • Simplified Chinese, plus missing translations filled in for the other languages. • Send without notification: long-press the send button. • Sending an invite opens the chat with that person and shows whether the invitation is pending or declined. The new-chat picker has an "Invite new person" tile. • A chat whose contact was deleted now says so and offers to delete the chat. • Auto-delete now runs even while the app is closed, and catches up whenever you open or unlock the app. • Auto-delete periods now run from 24 hours to 2 weeks, and 2 weeks is the new default. Longer existing settings are shortened to 2 weeks; an update never makes your history last longer. IMPROVED • The day label stays pinned to the top of a chat while you scroll. • Chat font: a text size for chat threads, applied on top of your system text size. • Your avatar now appears on the Profile tab, and cropping saves exactly what the circle shows. • Notebook: notes show their first attachment as a tile. "Save to new note" keeps the text, and sent attachments keep their file names. • Redesigned PIN keypad with larger letter keys. The keypad always opens on numbers, so it never shows whether your PIN contains letters. • The whole app now works on smaller iPhones and at large text sizes. • Taking a photo or picking media no longer locks the app behind the picker. Recording a video gets five minutes before the app locks. • Turning several protections off in a row asks for your PIN once, then accepts further changes for 30 seconds. • The voice recorder no longer jitters under your thumb. • Face ID no longer freezes the unlock screen. There's no black screen after Face ID on first launch, Home no longer freezes when you return to it, and tab bar icons no longer jump. SECURITY • Every message command is checked against its verified sender, so no one can send a command that appears to come from someone else. • Safety numbers to verify a contact, and a warning when a contact's key changes. • Wrong PIN limit: choose a maximum (3 to 10, default 5), with growing delays and an option to erase the app's data after the last attempt. Weakening a security setting asks for your PIN again. • Downloaded attachments are checked against a hash declared by the sender. • Stored encryption sessions are now encrypted, and your long-term private key is no longer kept inside them. • The database zeroes deleted content and clears its write-ahead log every time the app locks. Queued uploads are stored encrypted, and leftover temporary files are removed at startup. • The account store and attachments use Apple's strictest Data Protection class, so they can't be read while your iPhone is locked. Keylane data is excluded from device backups and transfers to a new iPhone. • An incoming call no longer opens a locked app, and app content is hidden in the app switcher. • A call link opened while the app was locked no longer dials by itself after you unlock. • The incoming-call screen never shows a caller name supplied by the server, and Keylane calls stay out of the Phone app's Recents. • Passwords copied from the notebook stay on this iPhone (no Universal Clipboard) and clear from the clipboard after 60 seconds. • The app keeps no logs in release builds. • A malformed message can no longer crash the app. • Attachments and lookups for contacts on other servers now go through your own server, so other servers never see your device's address.
