 ## [Unreleased]
 
+## [1.2.0] - 2026-06-11
+
+### Added
+
+- Subdomain actions: `GetSubdomainsAsync`, `GetSubdomainAsync`, `AddSubdomainAsync`, `UpdateSubdomainAsync`, `DeleteSubdomainAsync`, `MoveSubdomainAsync` — with the `Subdomain` read model and the `RedirectStatus`/`WebalizerVersion`/`WebalizerLanguage` enums (`add_subdomain`/`get_subdomains`/`update_subdomain`/`delete_subdomain`/`move_subdomain`). `AddSubdomainAsync` returns the created host name. Note: KAS provisions a new subdomain asynchronously (`in_progress = TRUE`) and rejects updates until that clears
+
+### Changed
+
+- Introduced an internal `IKasTransport` seam and added wrapper-level client contract tests (behaviour-preserving; no public API change)
+
+## [1.1.0] - 2026-06-11
+
 ### Added
 
-- Raw-SOAP transport for the KAS API that works around the faulty `Result`/`return` WSDL declaration
-- Session authentication (`plain` login → session token) with automatic reuse and refresh
-- Automatic flood throttling based on the `KasFloodDelay` returned by each call
-- `Map`/`Array` response parser into plain .NET objects
-- Mailbox actions: `GetMailAccountsAsync`, `AddMailAccountAsync`, `UpdateMailAccountAsync`, `DeleteMailAccountAsync`
-- Mail-forward actions: `GetMailForwardsAsync`, `AddMailForwardAsync`, `DeleteMailForwardAsync`
 - Account read actions: `GetAccountSettingsAsync`, `GetAccountResourcesAsync`, `GetDomainsAsync`
 - Typed account read actions: `GetAccountSettingsTypedAsync`, `GetAccountResourcesTypedAsync`
 - Subaccount actions: `AddAccountAsync`, `GetAccountsAsync`, `GetAccountAsync`, `UpdateAccountAsync`, `DeleteAccountAsync`
 - Account settings/superuser actions: `UpdateAccountSettingsAsync`, `UpdateSuperuserSettingsAsync`, `UpdateChownAsync`
 - DNS zone-record actions: `GetDnsRecordsAsync`, `GetDnsRecordAsync`, `AddDnsRecordAsync`, `UpdateDnsRecordAsync`, `DeleteDnsRecordAsync`, `ResetDnsSettingsAsync` — with the `DnsRecord` read model, the `DnsRecordType` enum plus a raw-type escape, and automatic `zone_host` trailing-dot normalization. Note: `ResetDnsSettingsAsync` is destructive — it discards all custom records of the zone
 - DynDNS user actions: `GetDynDnsUsersAsync`, `GetDynDnsUserAsync`, `AddDynDnsUserAsync`, `UpdateDynDnsUserAsync`, `DeleteDynDnsUserAsync` — with the `DynDnsUser` read model (`add_ddnsuser`/`get_ddnsusers`/`update_ddnsuser`/`delete_ddnsuser`)
-- Subdomain actions: `GetSubdomainsAsync`, `GetSubdomainAsync`, `AddSubdomainAsync`, `UpdateSubdomainAsync`, `DeleteSubdomainAsync`, `MoveSubdomainAsync` — with the `Subdomain` read model and the `RedirectStatus`/`WebalizerVersion`/`WebalizerLanguage` enums (`add_subdomain`/`get_subdomains`/`update_subdomain`/`delete_subdomain`/`move_subdomain`). `AddSubdomainAsync` returns the created host name. Note: KAS provisions a new subdomain asynchronously (`in_progress = TRUE`) and rejects updates until that clears
