June 2025 monthly summary for wowsims/cata focusing on Dynamic Target Management and State Control in Simulation. Delivered consolidation and enhancement of target handling, enabling dynamic enabling/disabling of targets, and added test utilities to support controlled AoE scenarios and migrations. Updated AI/encounter logic to respect target states and prepared the codebase for target-state migrations.

May 2025 performance summary for wowsims/cata: Focused on reliability, testability, and Phase 4 readiness. Key features delivered include SimEnchant proto ItemType field to automatically pick the correct slot during unit tests, and automated unit testing for all registered enchant effects. Phase 4 readiness was advanced with gear presets updates (P4 BiS, Phase 4 presets) and launch status updated to Phase 4. Extensive trinket/proc data fixes across The Hungerer, Idol of Battle, Fall of Mortality, Coren's Coaster, Heartsong, Gnomish X-Ray, and related enchantments improved simulation fidelity. Substantial code cleanup and maintainability improvements were completed, including removal of deprecated AddWeaponEffect(), deprecated on-use factory functions, and deprecated ProcStatBonusEffect fields, along with test stability improvements from a label revert in StatBuffAura tests.

April 2025: Provided key feature delivery in wowsims/mop by introducing a Nerf state selector for the Blackhorn encounter, enabling granular control over difficulty through adjustments to the Power of the Aspects debuff and its damage multipliers. This change enables precise tuning, supports data-driven balance experiments, and improves QA coverage. No major bugs fixed this month in mop.

February 2025: Delivered key features, stability improvements, and accuracy enhancements for Mop. Focused work included UI exposure of experimental features, feral druid burst optimization, and expanded phase-based simulations, along with simulation/test improvements that sharpen decision-making for DPS/healing rotations and raid planning.

Concise monthly summary for wowsims/mop in 2025-01 emphasizing features delivered, major bugs fixed, impact, and technologies demonstrated. In January, the team focused on solver robustness, safe architectural refactors, extensibility, and performance-oriented improvements that deliver clear business value and better developer experience. Highlights include solver reliability for hard gear sets, preserved randomness for UI/testing realism, safer handling of global state, and enhanced configurability through user-defined spell mods, plus tooling for profiling and UI enhancements.

Delivery highlights for 2024-12 in wowsims/mop focused on tuning feral druid rotation, weave optimization, and timing to maximize DPS while harmonizing cooldown usage. Notable changes include synchronized cooldowns with external procs, improved bleed timing and clipping accuracy, and proactive Maul/GCD handling to better leverage Rage windows. Test coverage expanded to validate core cooldown interactions and edge cases.

Concise monthly summary for 2024-11 focused on delivering realistic, reliable raid simulation improvements for wowsims/mop and enhancing the user-facing planning tools. Key features delivered and major improvements: - Baleroc Encounter AI and Preset Builds: Implemented Baleroc encounter AI with support for simulated tank swaps and a ramping 3-stage healing model; added MT and OT preset builds (commits a633c1d1..., 666b0999..., f14240d6...). - Tank Sim Healing Model: Absorb Shield Component added to improve survivability realism, especially during Decimation Blade windows (commit 997cf12e...). - Tank Sim Healing Model: State Leak Fix addressing a leak in the healing model (commit d7200b6d...). - Trinket/Proc System Improvements and APL Enhancements: Extensive refactor and feature work for trinket procs and APL, including custom proc conditions, trinket-agnostic APL, optional filtering for stacking procs, and Max Remaining ICD handling (multiple commits including b8ba62f1..., 0c5b2379..., 7da44bf6..., 52474412..., f39edc7d8..., 0a92dcce..., a7320dc7...). - Outbreak/Trinket Procs Bug Fixes: Fixed final Outbreak check when 2 Strength proc trinkets are equipped (commit a2fc41ec...). - General Bug Fixes and Behavioral Tweaks: Decimating Strike debuff no longer applies on avoided strikes; Blaze of Glory: OT did not steal second stack on Decimation Blade unless required; Blaze of Glory healing now applies to tank for gained max HP; Baleroc OT preset absorbFrac set to 0 for binary checks; removed 0-healing reset tick; adjusted min ICD thresholds and UI cleanup as part of ongoing stabilization. - Performance and Reliability improvements: Auto-Reforge LP solver timeout reduced from 60s to 10s; max iterations increased to 150k; activated cooldowns analog to NumEquippedStatProcTrinkets; various solver and UI improvements to speed up planning cycles and reduce wall-clock time. Overall impact and business value: - Realism and accuracy: The Baleroc AI and MT/OT presets, absorb shield component, and timing fixes yield more trustworthy raid simulations, improving planning confidence for raid leaders and DPS/healers optimization. - Reliability and stability: State leaks and UI-related issues addressed, with more robust handling of trinket procs and APL integration, reducing flaky results. - Performance and scalability: Solver timeout and iteration enhancements keep the planning flow responsive on a wider range of hardware, enabling faster iteration and decision-making. Technologies/skills demonstrated: - Simulation modeling: tank healing, absorb shields, and encounter AI - AI and scheduling logic: tank swaps and healing ramp, Decimation Blade windows - APL and proc system engineering: trinket checks, custom proc conditions, APLValueTrinketProcsMaxRemainingICD - Tools and performance: LP solver tuning, UI cleanup, reliability fixes - Debugging and quality practices: edge-case fixes (OT healing edge-case, 0-healing reset, avoided-strike debuff) and stability hardening

Month: 2024-10 — wowsims/mop delivered a targeted enhancement to enable secondary tank targeting in preset target configurations, enabling accurate modeling of tank swaps in encounters and improving planning fidelity. Key changes include updates to proto definitions and simulation logic to accommodate a second tank managing a target. While no major bugs were reported this period, the feature lays groundwork for broader encounter scenarios and more realistic DPS/encounter simulations. Overall impact: higher fidelity combat simulations, better planning data for teams, and a more robust, extensible data model. Technologies/skills demonstrated: protobuf/proto schema evolution, simulation pipeline changes, and careful coordination with repo changes to maintain backward compatibility and test coverage.
