What's New in v1.4.0

Added

  • Unified chat settings dialog — the middle piano key in the chat input bar is now a Settings button. Tapping it opens a dialog where you can configure Agent, Model, and Variant for the current session. Changes are committed on Confirm and reverted on Cancel (committed/draft separation). Selections are persisted per-session and restored on re-entry.
  • Variant selection — choose a specific model variant (e.g. different quantization levels) when the server provides variants. The selected variant is sent in the prompt request so the server uses the exact configuration you picked.
  • Provider/Model API — new GET /provider endpoint support with ProviderList, ProviderInfo, and ProviderModelInfo DTOs. Models are listed with their provider name, model name, and available variants.
  • Selection persistence — Agent, Model, and Variant choices are saved per-session to ConnectionPreferences and automatically restored when re-entering a chat.
  • Time-based session grouping — sessions are grouped by time: Today, Yesterday, This Week, Older. Sticky group headers with surfaceVariant background. Powered by SessionGrouper utility with relative time display.
  • Relative time display — session timestamps show "just now", "5m ago", "2h ago" instead of absolute dates for recent sessions.
  • Session search — search bar at the top of the project sessions screen with debounced filtering (300ms). Filters sessions by title.
  • Active session status dots — green pulsing dot (StatusDot) indicates active/busy sessions. ActiveSessionStore tracks session status from SSE events.
  • Project busy indicator — animated dot on project cards when any session within that project is actively running.
  • Child session tree — expand/collapse child sessions under their parent session. Indented tree layout (24dp indent) with chevron toggle. ChildSessionStore manages parent-child relationships via GET /session/children API.
  • Compact density mode — optional compact display density for the sessions list, persisted in ConnectionPreferences.
  • Session summary stats — each session card shows quick stats: number of additions (+N), deletions (-N), and file changes (Ff) derived from tool calls.
  • Agent load failure retry — when the agent list fails to load, a retry button appears in the chat screen instead of silently failing.
  • New SSE event handlers — session.status and session.children events processed in ChatViewModel for real-time status and hierarchy updates.
  • New MessagePart types — support for file, agent, snapshot, patch, retry, compaction, subtask part types (previously only text, tool-call, thinking).
  • Session API endpoints — GET /session/status and GET /session/children for session status polling and child session discovery.
  • session.deleted SSE handler — deleted sessions are immediately removed from the list without waiting for a manual refresh.

Changed

  • Chat input bar middle key — changed from model name display to Settings trigger (icon). Tapping opens the unified settings dialog instead of a model dropdown.
  • TopAppBar AgentPicker removed — the agent picker button previously in the top bar has been deleted. Agent selection is now exclusively in the Settings dialog.
  • Deleted dead code — removed ModelSelector.kt, ContextUsageDisplay.kt, AgentPickerButton.kt, and showAgentPicker state — all superseded by the unified settings dialog.
  • SessionInfo DTO expanded — added archived, partID, and SessionPermission pattern fields.
  • SessionsScreen redesigned — full rewrite with time grouping, search, status dots, child trees, and summary stats. Now uses SessionsUiState with search/grouping/agentError fields.
  • Removed eye button from chat top bar — child session visibility toggle moved to project session list.
  • Updated availableModelsError state handling in ChatViewModel.
  • Added diagnostic SSE event logging (SSE DIAG: prefix) for future debugging.

Fixed

  • SSE generation mismatch (critical) — root cause of streaming not working. ChatViewModel.subscribeToEvents() read repository.currentGeneration which could be higher than the SSE service's actual generation (e.g. after network recovery callback incremented it). The strict gen < subscribedGeneration filter discarded ALL events including message.part.delta and session.idle. Text appeared all at once (via fallback polling) and spinner persisted until 120s watchdog timeout. Fix: adopt the service's generation when mismatch detected instead of discarding events.
  • SseForegroundService null-intent recovery — when Android restarted the foreground service (e.g. after memory pressure), the null intent guard called stopSelf(), permanently killing SSE. Now recovers using repository.currentGeneration to resume the SSE subscription.
  • session.idle streaming state cleanup — force-clear all streaming state (isStreaming, isSending, streamingSegments, pendingAssistantMessageId) in session.idle handler's no-content guard path, instead of leaving spinner visible indefinitely.
  • Model list display — fixed ProviderList DTO to correctly parse server's {all: [...]} provider format. Created ModelLimitInfo data class to handle server's limit field (object with context/input/output keys instead of plain integer).
  • ModelRef construction robustness — buildModelOptions() now uses model.id.ifBlank { modelKey } instead of raw map key, preventing mismatch when the server returns a different model ID than the map key.
  • Variants sorted — variant list is now alphabetically sorted for stable UI display order.
  • Bidirectional normalize — normalizeSelectionState() now validates both committed and draft selections (previously only draft), preventing stale references after restoreSelection.
  • modelName 3-tier fallback — display label falls back through model.name, model.id, mapKey instead of just model.name and mapKey.
  • Child session dedup — fixed duplicate child sessions appearing in the list. Added dedup helper and unfiltered child session lookup.
  • Removed hide gate — child sessions previously required a "show hidden" toggle to appear; now always visible in the tree.
  • Session refresh guard — added guard to prevent concurrent session list refreshes from corrupting the UI state.
  • Startup crash when server unreachable — deferred SSE service start until after a successful connection is verified, preventing crash on app launch when the saved server is offline.
