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.
Shift4 ships Gift Card & Loyalty 26.2 with international API updates alongside POS patches
Shift4 runs parallel release tracks for its hospitality POS (Venue), loyalty/gift card platform, and Customer Hub, each on different cadences. The Gift Card & Loyalty 26.2 release and multi-language versions (French, Portuguese) are the most substantive this cycle, pointing to active geographic expansion of the loyalty product. Customer Hub ships weekly and added Payment Links in w35.

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.

Shift4 is building the loyalty and gift card platform as a standalone product line alongside the venue POS. The Customer Hub's weekly cadence and the Payment Links addition suggest active development on the commerce-enablement side, with international language parity signaling deliberate expansion beyond the US hospitality market.
Given the parallel international loyalty releases and Customer Hub's feature pace, Shift4 appears to be converging venue POS, loyalty, and payments into a more unified merchant-facing portal. Expect tighter integration between the Customer Hub and venue POS reporting over the next few cycles.
