v10.16 2026-07-22 WeKan ® release

This release fixes the following bugs:

• FerretDB now defaults to polling-only on all platforms, fixing high FerretDB CPU
  (#6503). FerretDB v1 can tail an OpLog for
  real-time updates, but on its SQLite backend Meteor's tailable+awaitData OpLog tail keeps
  FerretDB CPU pinned (reporters saw ~190–390% even when idle; a 2-core VPS maxed out and WeKan got
  stuck on the loading spinner), and a struggling tail also shows up in the log as oplog catching up took too long, stalling board and login loading. Even with the FerretDB-side mitigations the
  peg persisted on real deployments, while polling-only reliably drops CPU to ~10%. So polling is
  now the default on every launcher (snap, bundle, Docker/compose, Windows, Sandstorm);
  WEKAN_FERRETDB_OPLOG defaults to false. The OpLog remains available as opt-in
  (WEKAN_FERRETDB_OPLOG=true, or on snap snap set wekan wekan-ferretdb-oplog=true). The calmer
  polling throttle and SQLite pragma tuning keep poll-and-diff cheap. Thanks to xet7 and the
  FerretDB high-CPU reporters.

• i18n never gets stuck showing raw translation keys if a dynamic language import fails
  (related to #6503). TAPi18n.init() awaited a
  dynamic import('./data/en.i18n.json') and only marked i18n ready afterwards, so if that lazy
  chunk hung or failed — e.g. a stale snap client bundle after a refresh — the whole UI showed raw
  keys (like changeLanguagePopup-title) forever with no recovery. The default English is now
  statically bundled and registered first (the UI is always readable), and the dynamic load is
  bounded by a timeout so readiness is reached in every path. Note: this hardens the raw-key
  symptom; the dead OIDC/Register buttons in that report point to a stale dynamic-import bundle
  cache on the snap (a hard reload / clean snap rebuild is the confirming test), not a change in
  WeKan's login code (which is unchanged between 10.11 and 10.13) — and the FerretDB polling-only
  default above also removes the oplog catching up took too long stalls that make the login page
  slow to become interactive. Thanks to Alishara and xet7.
