What we shipped, when, and what broke. Including the breakages.

“The big one — cross-run analytics in the trace UI. You can finally compare 30 days of runs without leaving the dashboard.”

• addedCross-run analytics: percentiles, cohort comparisons, regression overlays in the trace UI
• addedlattice.evals.diff() — compare evaluator scores across two model versions
• addedPython SDK reached parity with TypeScript SDK (one minor behind, scheduled to close in v1.5)
• changedDefault rate limit on Free tier raised from 100/min to 200/min
• fixedStep retry exponential backoff was not respecting jitter when concurrency = 1 (regression in v1.3)
• fixedOpenTelemetry exporter sometimes dropped span links on long-running runs (>4h)

• fixedTrace UI search-by-step-name was case-sensitive; fixed to be case-insensitive
• fixedSub-agent handoff context occasionally dropped trailing 4KB on Anthropic provider
• securityBumped jose dependency to 5.10.0 for the JWT-validation CVE patch

“Self-host on Kubernetes is now production-grade. The Helm chart had been honest-but-rough; we rewrote it from scratch with a real Operator pattern.”

• addedLattice Operator for Kubernetes (alpha → beta) — full lifecycle management of self-hosted runtime
• addedHelm chart v2 — backwards-compatible install, breaking changes documented
• addedPre-built rubrics: faithfulness, tone, format-adherence, citation-presence
• changedTrace retention defaults: Free 7d, Team 30d, Scale 365d
• deprecatedlattice.runs.simple() is deprecated; use lattice.runs.create({ resumable: false }) instead. Removal in v2.0.

• addedInline evals — attach evaluators to any agent, sample production traffic, alert on regressions
• addedSlack and PagerDuty webhook integrations for regression alerts
• changedPricing simplified — moved to a single per-step rate; per-tenant volume tiering preserved on Scale
• fixedCold-start latency for managed cloud reduced from p99 4.2s → 1.1s

• addedGo SDK (pre-1.0) — focused on runner workloads
• addedlattice.trace.replay() — exact-input replay against any model version
• fixedMemory leak in long-running TS workers (>24h uptime)

“Lattice is generally available. Apache 2.0 runtime, managed cloud, $0/step Free tier, real OpenTelemetry traces.”

• added1.0 stable API — no breaking changes inside major version
• addedSOC 2 Type II report (audited by A-LIGN)
• addedGDPR and DPA documentation in /docs/legal
