June 2026 — Changelog

Jun 1 v6.0.199→215 DEV Fixed a serious bug: a sync between your own devices could accidentally erase another account's data on the same device — sync now never destroys, only adds or restores

Jun 1 — DEV Removing a connection on one device now reflects consistently everywhere: vault, sidebar, and chat

Jun 1 — DEV A "ghost" connection with no way to remove it now has a dedicated delete button

Jun 1 v6.0.199→215 PROD The set of fixes against cross-device data loss reaches production

Jun 2 — DEV Internal migration to a newer, more stable version of the backend language

Jun 2 — DEV Security audit of local password verification; fixed a case where a correct password was rejected as incorrect after reloading the page

Jun 2 v6.0.221 DEV Fixed translations for "delete local data" and account recovery, in 42 languages

Jun 2 — DEV Fixed a visual-honesty bug: a corrupted file in the vault stopped showing its warning after reloading the page

Jun 3 v6.0.224→225 DEV Fixed a case where the system rejected a correct password when trying to delete data, by verifying against the server instead of failing locally

Jun 3 v6.0.225→227 DEV Full verification that cross-device state changes (connection type, sync) and delete/restore history actions apply correctly

Jun 3 v6.0.215→228 PROD First stable deploy to production after the language migration; includes password verification with server backup, "delete local data", and orphaned file cleanup

Jun 3 v6.0.229 DEV Fixed a reconnection warning that repeated endlessly after signing out

Jun 3 v6.0.230 DEV Fixed a connection status label that sometimes went stale in the contact list

Jun 3 v6.0.231 DEV Your own reactions to a message now also sync to your other devices

Jun 3 v6.0.232 DEV Fixed a case where the profile photo didn't update on all devices if one was offline

Jun 3 v6.0.228→233 PROD Fixed a real bug in cross-device file thumbnail recovery; fixed three bugs in the connection type indicator (direct/relay/mirror) that sometimes showed something different on each end

Jun 4 v6.0.234 DEV Complete redesign of conversation muting: sound muting is per device, push notifications are an account preference, and muting a conversation is private; muted taps are still logged visibly

Jun 4 v6.0.235 DEV Fixed a bug where some notification sounds didn't play under certain browser conditions

Jun 4 v6.0.236 DEV Fixed a bug where a muted conversation started sounding again after reloading the page

Jun 4 v6.0.237 DEV Translations for the new mute system integrated in 42 languages

Jun 4 v6.0.238 DEV Fixed a bug that prevented the app from loading in Thai

Jun 4 v6.0.233→239 PROD The complete conversation-muting redesign reaches production, along with the Thai-language fix

Jun 4 v6.0.240→241 DEV Consolidated all internal cryptography into a single shared component, with no user-facing changes

Jun 4 — DEV Found a critical bug in backups: since late May they hadn't included messages, due to an undetected export error — fixed; no real backup was lost, and the app now shows what each backup contains

Jun 4 v6.0.242→243 DEV New backup format tested with real data; new feature to export all your data in a universal readable format, designed to let you take your information wherever you want

Jun 4 v6.0.239→243 PROD Consolidation of internal cryptography, the new backup format, and readable-format data export reach production

Jun 4 v6.0.243→244 DEV Backup and data export translations integrated and fixed in 42 languages

Jun 5 v6.0.245 DEV Renamed the export feature to "Readable copy", clearer than the previous technical term, in 42 languages

Jun 5 — DEV Dropped support for reading backups in the old format (prior to the May redesign); there was no real data in that format

Jun 5 v6.0.246 DEV Fixed a real deadlock in large file transfers that could leave a transfer hanging indefinitely

Jun 5 v6.0.243→245 PROD Readable copy and the backup translations, in 42 languages, reach production

Jun 5 v6.0.247→250 DEV Found and fixed a real divergence between the same user's copies on two devices: some messages were getting corrupted and losing their order after a failed transfer; the vault can now only be enriched, never degraded

Jun 5 v6.0.245→250 PROD Fixed a cross-device sync bug that in some cases could reorder or damage messages

Jun 5 — DEV Designed a cross-device integrity verification layer that mathematically compares the full content of each copy to detect any difference

Jun 5 v6.0.251 DEV Implemented the first phase of the new integrity verification: detects whether two copies on your devices have diverged

Jun 6 — DEV The first real test of the new integrity verification found a divergence no previous system could detect: messages marked as read on one device but not another

Jun 6 v6.0.254→255 DEV Built the second phase: when a divergence is detected, the system automatically repairs it by merging both copies without losing information

Jun 6 v6.0.256 DEV Verified over a full night of real usage: divergent copies repaired themselves, with no intervention

Jun 6 — DEV Full 17-hour investigation into a possible browser memory issue: ruled out, the app has no memory leaks

Jun 6 v6.0.257 DEV Fixed a loop where the app repeatedly requested a file thumbnail that never arrived; added an internal memory monitor, observation-only

Jun 6 v6.0.258 DEV Removed two obsolete internal database fields; fixed two real bugs found in the process: the account-pause toggle didn't reflect the real state, and accounts in the grace period couldn't sign in to top up their balance

Jun 6 v6.0.250→258 PROD Fixed the account-pause toggle and access during the grace period; the cross-device self-repair system (verification + automatic repair) reaches production

Jun 6 — DEV Reorganized several large internal files into smaller, more maintainable pieces, with no behavior changes

Jun 7 v6.0.258→263 PROD Answering a call from any of your devices now works correctly — previously it only connected if you answered from the primary device

Jun 7 v6.0.264 DEV Built a call alert for when you don't have the app open (a "calling" notification, not just a text message)

Jun 7 v6.0.265→266 DEV Fixed a routing bug: call alerts were arriving as regular notifications instead of signaling a real call

Jun 7 v6.0.266 DEV Extended the call-answer window so a phone with the app closed has real time to launch and answer

Jun 7 v6.0.266 PROD The call alert for when you don't have the app open reaches production

Jun 7 v6.0.267 DEV Call alert translations reviewed and fixed in 42 languages

Jun 7 — DEV Full pre-launch audit: verified that billing, monitoring, account tiers, and legal pages already worked; added the mandatory legal-acceptance checkbox at signup

Jun 7 — DEV Strengthened protection against automated signups and abusive connection requests

Jun 8 — DEV Unified into a single place the logic for merging data when two devices have diverged, previously duplicated inconsistently across five places

Jun 8 — DEV Security audit: fixed three sensitive-data comparisons that weren't constant-time

Jun 8 v6.0.270→273 DEV Fixed a real regression: PDF previews had gone a week without generating, due to a silent error; fixed. One specific PDF still hangs the Chrome browser due to a Chrome bug, not our app

Jun 8 — DEV Fixed a real security bug: an endpoint could be used to make the server contact unauthorized internal addresses

Jun 8 v6.0.274 DEV Vault-loss detection system: if a device unexpectedly loses all its local data, it's now detected and flagged instead of starting up as a new account

Jun 8 v6.0.276→277 DEV Fixed video thumbnails that weren't generating for certain video files

Jun 8 v6.0.266→277 PROD Large cumulative update: full call alert, legal checkbox at signup, security improvements, PDF and video preview fixes

Jun 8 v6.0.278 DEV Fixed a real bug where a phone could permanently lose its session after an update or a long pause

Jun 8 v6.0.277→278 PROD The fix for lost phone sessions reaches production

Jun 8 — DEV Fixed 4 additional security findings from the audit (connection limits, data sizes, cleanup after failures)

Jun 9 — DEV Fixed a real bug where the direct connection between your own devices would drop and not recover

Jun 9 — DEV Unified into a single menu what used to be two separate, contradictory menus for managing a conversation

Jun 9 — DEV Fixed some conversation preferences (allow taps, pause) not syncing between your devices, unlike mute

Jun 10 v6.0.285 DEV Fixed the last cross-device connection bug: having two browser tabs open no longer interrupts sync

Jun 10 v6.0.278→285 PROD The definitive cross-device connection stability fix reaches production

Jun 13 — DEV Technical verification after migrating the development server to a new operating system; fixed outdated build tools

Jun 14 v6.0.297→300 DEV Fixed several security and reliability bugs in payments, call signaling, and internal cryptography

Jun 14 v6.0.300 DEV Switched the vault key-derivation system to a more robust one; old vaults (no real users yet) renew automatically

Jun 15 — DEV Raised the file size limit from 50 GB to 1 PB — the real limit was always the device's free space; improved the warning when a device runs out of space mid-way through a long transfer

Jun 15 — DEV Optimized large file transfers to read each file once instead of twice

Jun 15 — DEV Fixed a real bug: after a restart with no saved session, the app could open the vault without the correct key and show intact messages as "corrupted"

Jun 15 — DEV Audited a real 10 GB transfer: confirmed there are no hidden technical limits

Jun 15 — DEV New admin panel to reconcile daily payment revenue against internal records

Jun 15 v6.0.301 PROD Full close-out of the system-wide security audit: dozens of findings fixed, from cryptography to session management

Jun 15 v6.0.303 PROD The new push notification key reaches production

Jun 16 v6.0.312→315 DEV Fixed an improper rejection in the Brave browser that blocked sending large files, due to a privacy limitation in the browser itself

Jun 16 v6.0.315 DEV An interrupted transfer (sign-out, reload, lost connection) can now be resumed with no time limit

Jun 16 — DEV If the device receiving a file disappears for good, another of your devices receives it directly from the sender

Jun 16 — DEV Unified into a single place how a file is rendered in chat, so it always looks the same regardless of device or timing

Jun 16 v6.0.325 PROD Complete hardening of large file transfers (unlimited-time resume, cross-device recovery, consistent appearance), tested with real 5 GB sends

Jun 18 — DEV Finished unifying the file view in chat: pausing and canceling a transfer now look the same in every case

Jun 18 — DEV Fixed a case where deleting a file mid-sync between your devices left a half-orphaned file on the other device

Jun 19 v6.0.326→328 DEV Fixed a real cross-device propagation bug when forwarding a file to a contact

Jun 20 — DEV Unified how file receipt is displayed, whether it comes from a contact or one of your own devices

Jun 21 v6.0.335 DEV Unified the "queued"/"receiving" view for all file types, previously only images had it

Jun 21 v6.0.336→338 DEV Fixed a real bug: deleting a file while it was transferring to a contact could leave them with a "receiving" bubble stuck forever; also fixed sending a file not scrolling the view to show it

Jun 21 v6.0.339→342 PROD Internally renamed the backend service (no visible change); removed the now-obsolete waitlist admin tab; fixed a translation bug in transfer progress

Jun 21 — DEV Translations for file transfer alerts, and a notice to the sender when the recipient deletes a file, in 42 languages

Jun 22 — DEV Investigated and fixed a real bug that broke the direct connection between your own devices when deleting a large file mid-transfer

Jun 22 — DEV Confirmed that a suspected cross-device connection freeze was a one-off environment issue, not a code issue; tested a full 5 GB sync and deletion mid-transfer

Jun 22 v6.0.346→348 DEV Simplified the system that decides which device leads the connection between your own devices

Jun 23 v6.0.348 DEV Confirmed a single, stable connection between your own devices, in both directions

Jun 23 v6.0.350 DEV Fixed a real bug where one account's data could mix into another account's sync on the same browser; decided to fully support multiple accounts in the same browser

Jun 23 v6.0.351 DEV First phase of multi-account support in the same browser: each account now has its own isolated session

Jun 23 v6.0.352 DEV Each account in the same browser now also has its own isolated cryptographic keys

Jun 23 v6.0.353→354 DEV Each account can now independently have its own connection "leader" device

Jun 24 v6.0.360 DEV Confirmed that a browser keeps only one active session at a time, even with multiple accounts saved

Jun 25 — DEV Locked the vault data schema ahead of commercial launch

Jun 25 v6.0.365→367 DEV Fixed a real problem when forwarding a file twice; forwarding a file is now always allowed even if it's already been forwarded before

Jun 26 v6.0.371 PROD Fixed a real duplication issue when forwarding files: the same encrypted file is now shared across forwards instead of being copied

Jun 26 — DEV Pre-commercial-launch audit; new billing toggles in the admin panel

Jun 26 — DEV Verified the feasibility of a native desktop version with full parity with the browser version

Jun 27 — DEV Closed out the pre-launch billing process: account tiers configured, reconciliation secret verified, founder mode decided

Jun 27 — DEV Confirmed that real payment had already been tested since April; fixed invoice numbering in the sister payment gateway

Jun 27 v6.0.373 DEV Fixed a file that got stuck "queued" forever; fixed recovery with the 24-word phrase returning to the sign-in screen

Jun 27 v6.0.374 DEV Instrumented a "database" error during sign-in from a second device, in order to diagnose it

Jun 28 v6.0.375 DEV Audited and fixed 207 translations that showed a raw key instead of readable text; found 104 phrases that only existed in the database, not in the source code

Jun 28 v6.0.379 DEV Notice when a connection request is rejected; a permanent, unobtrusive indicator for a paused or grace-period account instead of an interrupting warning

Jun 29 v6.0.381 PROD Fixed the paused-account indicator to update instantly; verified admin access to the servers in production

Jun 29 — DEV Strategic design: move backup and restore to a component shared with the rest of our products

Jun 29 — DEV Fixed a real bug where a contact's identity showed as "unknown" after restoring a backup

Jun 29 — DEV Backup and restore migrated to the shared component, tested and verified

Jun 30 v6.0.381→383 PROD Backup and restore on the new shared engine reaches production

Jun 30 v6.0.384 DEV Fixed a false identity-mismatch warning when opening the vault, following an earlier change to the identity fingerprint calculation
