• Sep 4, 2026 1.0.0
  ## [1.0.0] - 2026-09-04 The first stable release of Kairos. 🎉 ### Added - A complete Kairos visual and UX revamp built around the "Time through Glass" design language: atmospheric backgrounds, bounded translucent surfaces, precise typography and restrained depth in both dark and light themes. - A tactile completion control with immediate state changes and a short visual

  check animation. - A lightweight task-list layout that keeps titles fast to scan while making due dates, reminders, priorities, tags, sync and Astraea state easier to understand. - A reusable visual foundation for glass surfaces, section headers, completion controls and the primary task-creation action. - Refined onboarding, task editor, task details, settings and empty states. ### Changed - Dark mode is now intentionally designed as a near-black atmospheric surface, while light mode uses luminous cool neutrals instead of sterile white. - Task colors now act as restrained semantic indicators rather than filling every task row with a heavy card background. - Blur is limited to bounded interactive surfaces so the scrolling task list remains lightweight. ### Preserved - Offline-first behavior, encrypted local storage and secure key handling. - Optional encrypted Nostr synchronization and relay security restrictions. - Reminders, task status behavior, NIP-09 deletion semantics and Astraea calendar mirroring. - All 27 localizations and the existing Android application identity.\n\n### Release verification\n\n- Android release certificate SHA-256: `2c8cb5283f8cd83242d9a56b21959e7ce28165d366c962782186a06601b5f55f`
• Aug 25, 2026 0.1.3
  ## [0.1.3] - 2026-08-25 ### Fixed - The Android adaptive app icon: the foreground artwork was scaled to only 60% of the canvas and sat on a background color dark enough to read as flat black, so the launcher showed a large near-black ring around a small icon. The foreground is now cropped to its actual opaque bounds and rescaled to 72%, and the background color is a lighter mid-purple that reads as part of the design rather than as a rendering bug.
• Aug 20, 2026 0.1.2
  ## [0.1.2] - 2026-08-20 ### Added - A "Sync to Nostr" toggle for tasks that are already syncing, not just new ones: switching it off in the editor pins the task to this device and retracts its existing relay copy (and calendar mirror, if mirrored); switching it back on resumes publishing. Complements the existing "Sync task" action, which already covered the opposite direction for a task created local-only.

  ### Fixed - The Android app icon: the source artwork's own rounded-square edges reached the adaptive-icon safe zone boundary, so circular or squircle launcher masks cropped the glyph. The foreground layer is now generated with enough padding to sit fully inside the mask on every launcher shape.
• Jul 28, 2026 0.1.1
  ## [0.1.1] - 2026-07-28 ### Added - Task reminders. A task with a due date can carry several notifications ("at the due time", 5/15/30 minutes, 1/2 hours or 1 day before); setting a deadline for the first time adds a one-hour reminder that can be changed or removed. Reminders are handed to the system when the task is saved and delivered by it, so nothing runs in the background, and they follow the task to the account's other devices. A single switch in Settings turns them all

  off and back on without losing the per-task choices. - Astraea calendar integration. A dated task can be published as an Astraea calendar event, so it appears in that app's calendar and home-screen widget on the day it is due. Opt-in per task, from the editor. When both apps are installed, Kairos also sends Astraea a local instruction with an explicit notification request, independently of Nostr. - Local Kairos ↔ Astraea interoperability. Android uses an explicit, package-bound intent; Linux uses a per-user Unix-domain socket. Upserts, edits, unchecks and deletions are delivered through a versioned JSON protocol, with notification deduplication instructions for Astraea. - The Astraea calendar option is now available for dated tasks even without a Nostr account or selected relay; the local bridge works offline and Nostr remains the durable cross-device channel when configured. - Four more suggested relays (`relay.primal.net`, `relay.nostr.band`, `nostr.mom`, `relay.snort.social`) alongside the existing two, for redundancy when one is slow or unreachable. As before, none is selected unless the user taps it. - Relays on the local network can now be added to the ordinary relay list, not only to the dedicated home-relay slot, over `wss://` or plaintext `ws://`. Plaintext remains refused towards any host outside the local network. ### Fixed - A personal home relay using a `ws://` or private-network address was accepted by the interface but silently discarded when saved, and again when reloaded, so the setting was lost on restart. Relay normalization existed in three divergent copies; there is now a single one used everywhere. ### Security - Bounded the work a relay reply can impose. A relay answering a request with thousands of events carrying the account's public key and an invalid signature could block the interface for tens of seconds. Replies are now reduced before any signature verification, the amount verified per sync is capped, and verification yields regularly so the app stays responsive. - Closed several ways to write an internal address that got past the loopback/private-network refusal on public relay entries, including IPv4-in-IPv6 forms and integer notations such as `2130706433` or `127.1`. - Applied that same refusal to profile-avatar downloads, which follow redirects chosen by a remote host and previously had no such check. - Rejected relay URLs containing control characters or out-of-range ports instead of storing a normalized version of them. - Closed websocket connections to relays removed from the configuration instead of leaving them open until the app restarted. - Restricted Android TLS trust to the system certificate store.

  # Kairos v0.1.0 — Initial Release Kairos is an offline-first task manager with optional encrypted Nostr synchronization. ## Features - Create, edit, complete and delete tasks locally. - Offline-first encrypted local storage. - Optional NIP-44 encrypted synchronization over user-selected Nostr relays. - Self-custodial authentication with no centralized account.

  - Task descriptions, tags, priorities and colors. - Local reminders with timezone and daylight-saving support. - Optional Astraea calendar mirroring for dated tasks. - Deterministic Nostr event coordinates to prevent duplicate records. - Reliable deletion through encrypted tombstones and NIP-09 cleanup requests. - Per-task local-only mode for data that must never leave the device. - Relay URL validation and secure transport requirements. - Bounded relay fan-out, timeouts and hostile-relay protections. - Localization support for multiple languages. ## Security and privacy Kairos does not require a central server. Tasks remain local unless synchronization is explicitly enabled. Synchronized task data is encrypted before being published to Nostr relays. ## Validation - Full Flutter test suite passing. - Static analysis passing. - Relay and hostile-input integration tests included. - Astraea calendar interoperability covered by regression tests. This is the first public release of Kairos.
