+| **v1.19.1** | 2026-07-19 | **Bugfix / docs:** DEPENDENCIES — e2e requires `taler-helper-sqlite3` on mon PATH + preflight; README domains.conf documents **`lang`** column. |
 | **v1.19.0** | 2026-07-19 | **Feature:** domains.conf **`lang`** column (en\|fr) is the global UI language default per stack; i18n + HTML read `TALER_DOMAIN_LANG` / conf (FP profiles `lang=fr`). |
 | **v1.18.9** | 2026-07-19 | **Bugfix:** UI lang — *lefrancpaysan*/*francpaysan* always default **fr** unless `TALER_MON_LANG_SET=1` / `--lang`; workstation `TALER_MON_LANG=en` no longer locks English (host-agent + console_to_html). |
 | **v1.18.8** | 2026-07-19 | **Bugfix:** e2e wallet — require `taler-helper-sqlite3` on PATH; use absolute `node` + `timeout` instead of fragile `perl -e alarm` for wcli; clearer accept-uri errors (no raw alarm-shift noise). |
