+
+## Release Summary
+
+Enforces the previously unused `fa_lock_week` config (week 14) in the transaction builder. After the deadline, `/dropadd` blocks adding players FROM Free Agency while still allowing drops TO FA. Also includes a batch of performance PRs from the backlog that were merged between 2026.3.12 and this tag.
+
+## Changes
+
+### New Features
+- **Free agency lock enforcement** — `TransactionBuilder.add_move()` now checks `current_week >= fa_lock_week` and rejects FA pickups after the deadline. Dropping to FA remains allowed. Config already existed at `fa_lock_week = 14` but was never enforced. (PR #122)
+
+### Performance
+- Eliminate redundant API calls in trade views (PR #116, issue #94)
+- Eliminate redundant GET after create/update and parallelize stats (PR #112, issue #95)
+- Parallelize N+1 player/creator lookups with `asyncio.gather()` (PR #118, issue #89)
+- Consolidate duplicate `league_service.get_current_state()` calls in `add_move()` into a single shared fetch (PR #122)
+
+### Bug Fixes
+- Fix race condition: use per-user dict for `_checked_teams` in trade views (PR #116)
+
+## Deployment Notes
+- No migrations required
+- No config changes needed — `fa_lock_week = 14` already existed in config
+- Rollback: `ssh akamai "cd ~/container-data/major-domo && docker pull manticorum67/major-domo-discordapp@sha256:94d59135f127d5863b142136aeeec9d63b06ee63e214ef59f803cedbd92b473e && docker tag manticorum67/major-domo-discordapp@sha256:94d59135f127d5863b142136aeeec9d63b06ee63e214ef59f803cedbd92b473e manticorum67/major-domo-discordapp:production && docker compose up -d discord-app"`
