+## [0.6.0] - 2025-04-04
+### Added
+- Retry requests on network error and on HTTP 410 Gone response send by backend, which 
+  allows to implement more robust behavior on mobile devices (long polling requests 
+  to status endpoints are known to fail with network error when browser is in background,
+  and browser does go to background when SmartID app pops up).
+
+### Changed
+- use `web-eid` instead of legacy `hwcrypto`
