Three new posts (EN + ZH twins, og + banner each):
- n8n-v1-to-v2-upgrade-gotchas (devops): the seven deprecations that
surfaced upgrading 1.123.x → 2.40.1, decoded from the boot log —
telemetry schema rejection, N8N_WEBHOOK_URL rename, internal runner
deprecation, task timeout 300s→60s, two compression limits, v3
storage rename, plus the DB override that silently disabled the
AI sandbox.
- self-healing-digital-goods-entitlements (case-studies): the W1–W5
NocoDB → n8n → AList entitlement lifecycle. Build-time code sharing
for n8n Code nodes, MAX-expiry semantics, dry-run safety, daily
drift repair, CORS-not-HMAC reasoning, and the public→internal
NocoDB cascading-failure fix (504 → retry storm → 503).
- running-tts-as-a-service-with-token-sidecars (ai): a year-long TTS
service built on two cron containers that refresh Azure/Google
tokens into a shared file, with the speed/voice mapping layer.
banner-gen: center terminal body vertically so line counts shorter
than the fixed 690px panel don't leave a dead void at the bottom.
Verified via DOM measurement (gapAbove 104 / gapBelow 106).
