+| **v1.26.2** | 2026-09-06 | **Bugfix / urls:** missing merchant `/webui/version.txt` is **INFO** (earlier merchant SPA had stamp; current packages often omit; bank `/webui/version.txt` still present). |
 | **v1.26.1** | 2026-08-31 | **Bugfix:** public order settle accepts `StatusPaidResponse` (`refunded`/`refund_taken`); `paid`/`order_status` not on public GET. |
 | **v1.26.0** | 2026-08-30 | **Feature:** `--wallet-db PATH` / `--wallet-migrate` (taler-wallet-cli / taler-harness names) for e2e, ladder, zero-pay. TESTPAYSAN: one Quadlet `stage-testpaysan`; e2e token-pay via env `E2E_TOKEN_*` / `--choice-index`. Stack READMEs `README_testpaysan.md` / `README_mytops.md`. |
 | **v1.24.0** | 2026-08-30 | **Feature / zero-pay:** public-template pays as phase `zero-pay` (`check_zero_pay.sh`). Default merchant **stage.my.taler-ops.ch** (CHF:0 stickers). Wrapper `pay_talersticker_zero.sh` COUNT=100. TESTPAYSAN: empty POST `{}` + auto-confirm of bank wires (host `auto-confirm-withdrawals`). Not in default 4h PHASES (use COUNT=1). |
