+## 2026-06-09 — backend v2.11.6 + frontend v2.11.29
+
+**backend v2.11.6**
+- `fix(auth): pass pgUserId in TelegramLink upsert to prevent resolvePgUserId failure` — after `user.save()` the Postgres UUID is available on `user.pgId`; passing it as `pgUserId` in the `$set` lets `saveTelegramLink` skip the secondary lookup that was silently failing for some users (generic 500 "Telegram authentication failed"). Also expanded the catch-block keyword list to surface specific errors (missing/required/not configured/Cannot link) instead of swallowing them.
+
+**frontend v2.11.29**
+- `fix(seller): remove "درخواست جدید" button from seller request list view` — only buyers can create requests; button removed from seller dashboard header.
