Extract JVM_TOOLCHAIN_VERSION, COMPILE_SDK, MIN_SDK, and TARGET_SDK
into a shared BuildConstants object so all convention plugins reference
a single source of truth.
Breaking changes:
- 2FA enable changed from GET to POST with OTP verification body
- Backup code regeneration now requires OTP verification
- Account deletion requires OTP when 2FA is enabled
- New shared OtpVerificationDialog component in core/ui
- Fix OTP digit box layout (weight-based instead of fixed size)
Additive changes:
- Add effort (AnthropicEffort) and thinkingLevel (Google) fields to
Conversation, Preset, and ChatRequest models
- Add tool_options to Agent model and create/update requests
- Add artifacts field to EphemeralAgent
- Add remoteAgents to InterfaceConfig
- Add programmatic_tools and deferred_tools agent capabilities
- Add thinkingLevel parameter to EndpointParameterRegistry
SSE hardening:
- Implement mapSyncEvent() for resume state-snapshot protocol
- Preserve partial stream content on disconnect (don't wipe visible text)
- Persist conversation to Room on stream creation (not just on Final)
- Auto-reconnect SSE stream when network recovers via ConnectivityObserver
- Network-aware retries in SseClient (wait for connectivity, don't burn attempts)
- Add StreamEvent.Retrying for retry progress UI feedback
- Lazy connectivity observation (only when network error occurs)
- Clear draft/streaming state on SSE stream expiry
- Add isNetworkError flag to StreamEvent.Error for typed detection
Code quality:
- Remove [Comparison] debug Timber logs (perf overhead on every SSE event)
- Replace Log.d with Timber.d across feature modules
- Extract hardcoded OTP dialog strings to strings.xml for localization
- Parameterize OtpVerificationDialog labels for localizability
- Add auto-submit guard with reset on failure for OTP input
- Replace fake QR code generator with copyable otpauth:// URI
- Replace fragile OTP string matching with HTTP status code checks
- Consolidate identical request classes into OtpVerificationRequest
- Share isHttpStatus helper across settings module
- Remove duplicate verifyTempToken method (identical to verifyTwoFactor)
- Remove duplicate 2FA dialog composables from AccountSettingsScreen
- Extract shared resume stream logic to reduce duplication
- Guard no-op retryInfo state updates
- Move ApiException to core:common for cross-module access
- Document SseEventMapper single-stream threading constraint
Bump SUPPORTED_BACKEND_VERSION to 0.8.4, advance upstream submodule.
- Add official LibreChat repo as git submodule at upstream/ (pinned to v0.8.2)
- Create UPSTREAM_VERSION file to track which release the app targets
- Create /sync-upstream skill with Agent Teams workflow
- Add reference files for API, model, UI, and architecture mappings
- Update CLAUDE.md with upstream sync documentation
