TravelPerk is widening approval channels and pushing harder into North America.
TravelPerk's recent cadence is dominated by approval-channel breadth (Microsoft Teams alongside Slack, SMS for time-sensitive requests), North America support hardening, and operational basics like CSV bulk user upload and Dutch localization. An events-management platform got a brief mention. Sustainability is creeping in via CO2e in car search.
LNbits v1.6.0 replaces Python extension security reviews with WASM sandboxing — a new distribution model for Lightning tools.
LNbits v1.6.0 shipped WASM extensions: sandboxed plugins that can be written and shared without requiring core-developer security review, directly addressing the bottleneck that limited ecosystem growth. Lightning Addresses moved from extension territory into core, and the block explorer via Electrum and Bark (barkd) funding source added new infrastructure options. v1.6.1 followed with phoenixd node page, NWC false-failure fixes, and payments CSV comment export — iterative polish on the 1.6.0 surface.

The product is expanding the surface where approvals happen rather than reinventing the booking flow itself, betting that meeting approvers where they already work cuts trip-cycle time. The North America push (toll-free line, expense integrations, region-specific posts) signals a deliberate market focus. Expect continued surface expansion plus a more developed events product.
The next directional move likely deepens the approvals automation with policy-aware auto-approve rules and tighter ties between expense integrations and the booking flow. North America support hours and integrations will keep expanding to close the gap with regional incumbents.

The WASM extension model shifts security isolation from audit-based to runtime-sandbox-based, which should increase the throughput of the extension ecosystem considerably. Lightning Addresses as a core feature signals LNbits is moving toward being a complete Lightning wallet experience rather than just a developer toolkit. The multi-backend funding source expansion (Bark, Blink, phoenixd, LND gRPC self-payments) suggests LNbits is building toward being backend-agnostic across the Lightning node ecosystem.
WASM extension tooling will mature next — documentation, the vetted extension repository growing, and possibly browser-based WASM development support. Phoenixd's deepening integration (node page, preimage returns, mnemonic display) hints at a tighter mobile Lightning node story ahead.
