Notable changes in each Sugar release.

v3.10.0 - July 18, 2026

Task Orchestration ships as advertised - the 4-stage workflow (research, plan, implement, review) is now wired into the live execution path.

Task Orchestration - intelligent decomposition and execution of complex features through staged workflows and specialist agent routing
4-stage workflow: research, planning, implementation, review - with context accumulation across stages to .sugar/orchestration/{task_id}/context.md
orchestration: config block emitted by sugar init (detection rules, per-stage agents/timeouts, agent routing patterns)
--orchestrate and --skip-stages flags on sugar add (and the MCP sugar_add_task tool)
sugar orchestrate [TASK_ID] and sugar context TASK_ID CLI commands
Specialist agent routing (frontend-designer, backend-developer, qa-engineer, security-engineer, devops-engineer, code-reviewer, tech-lead, general-purpose)
Dependency-wave executor: sub-tasks persist to the queue and execute in dependency order, sequentially within each wave
Read-only research and planning stages (Read, Glob, Grep, WebSearch, WebFetch) so analysis stages gather context without writing files; configurable via read_only: false
Review stage runs the project test suite and fails the orchestration when require_passing: true
Orchestration exposed over MCP: sugar_add_task gains orchestrate/skip_stages, sugar_view_task surfaces stage, context_path, parent_task_id, assigned_agent, and sub-tasks

Wire TaskOrchestrator into SugarLoop - orchestration previously fell through to simulated output and sub-tasks were never persisted
Latent execute_work_item -> execute_work executor call bug, and the *ui*-matches-"build" router wildcard bug
Cascade-fail orphaned sub-tasks: dependents of a failed sub-task are no longer stranded in hold
Enforce configured per-stage and per-subtask timeouts (previously dead config) via asyncio.wait_for
Harden the plan parser: line-based parsing handles unbolded titles and dependency refs like "1 and 2", "1-3", "1 to 3"
Drop sentinel "none" dependency values that could strand a sub-task forever
One failed task no longer aborts the whole loop cycle

Intra-wave parallel subtask execution is planned future work; sub-tasks run sequentially within each wave today. See the Task Orchestration guide.

Security fixes, documentation overhaul, and new positioning as an autonomous issue resolution tool.

Add missing thread locks to MemoryStore.list_memories, count, and prune_expired
Replace silent exception swallowing with logger.warning() for vector deletion and unknown memory types
Fix .gitignore duplicate entries

Architecture.md - contributor-focused architecture overview with system diagram
Workflow examples - security auto-fix, bug triage, test coverage, code quality, feature development
Document hold, release, logs, and opencode CLI commands

Global memory layer and concurrency fixes.

Global memory store at ~/.sugar/memory.db for cross-project knowledge
New guideline memory type for standards that apply everywhere
--global flag for remember, recall, memories, forget, and memory-stats
sugar://global/guidelines MCP resource
Project-first tiered search strategy with reserved guideline slots

Six concurrency fixes across storage layer and core loop
Thread-safety improvements for subagent manager, issue response manager, and work queue

Goose integration guide and improved MCP setup.
