Dify connector changelog Use this page to decide whether a Dify connector change requires a new artifact, admission record, migration, caller update, or qualification result. It records only changes established from the reviewed Git range. Release status: the reviewed snapshot is not a tagged release. The repository tags 034a5206 as v1.0.0; the documentation revision is five commits later and still declares workspace version 1.0.0. Use full source, artifact, manifest, and provider identities to distinguish these states. Identify the exact version | Identity | Published v1.0.0 baseline | Reviewed source snapshot | | Source commit | 034a520608eea44e6b14e61c34734bd402d989c0 | 97be86e9efedf07ecf1783b03800f683f107fb04 | | Source position | Tagged | v1.0.0-5-g97be86e | | Publication status | Published tag in reviewed repository | Unreleased source in reviewed ancestry | | Workspace version | 1.0.0 | 1.0.0 | | Native AIP version | 1.0 | 1.0 | | Dify surface | One alias per configured app | Alias plus mode-projected app operations and Knowledge operations | | Credential model | One connector-wide app key | Per-app keys and independent Knowledge keys, with legacy app-key option | | Target placement | Bundled library connector | Separately built and admitted standalone host | An operator record for the reviewed snapshot needs the full source commit, tree, immutable image digest, manifest digest, connector version ID, release ID, descriptor hashes, and provider identity. The string 1.0.0 cannot replace that identity tuple. Reviewed source snapshot The entries below describe Dify-relevant differences between tagged v1.0.0 and 97be86e9. They are source changes, not evidence that an artifact was built, published, deployed, or qualified. Added • A frozen catalogue of 79 Dify operations pinned to upstream commit f8d47616c15d0959f604f6a5e2e1d32d3108991b. • Thirty-three app operation templates with mode-dependent projection. • Forty-six workspace-scoped Knowledge operation templates. • Per-app and per-Knowledge credential bindings. • Bounded query, JSON, multipart, binary, and response handling. • Typed Dify failure codes with retry and uncertainty metadata. • Composite health across every configured credential. • Cluster-safe task correlation through runtime profile state. • A dedicated aip-host-dify binary and common standalone image path. • Registry admission, tenant routing, leases, durable runtime storage, and recovery integration. • Standalone image and controlled product-fleet qualification procedures. Changed App aliases remain under cap:dify:. Each app now also publishes the operation suffixes permitted by its configured mode. | Mode | App operations | Alias | Total per app | | workflow | 23 | 1 | 24 | | completion | 19 | 1 | 20 | | chat | 27 | 1 | 28 | | advanced-chat | 29 | 1 | 30 | | agent-chat | 27 | 1 | 28 | | agent | 27 | 1 | 28 | Every configured Knowledge credential publishes 46 capabilities under cap:dify:knowledge::. The manifest is now descriptor-dependent. Callers must discover capability IDs instead of assuming the tagged baseline's one-capability-per-app surface. Credential isolation The tagged connector stored one shared API key. The reviewed connector stores separate app keys and separate Knowledge keys. The standalone host accepts a legacy global app key only when every app intentionally shares it. It cannot be mixed with per-app files and cannot authorize Knowledge operations. This is a deployment and secret-ownership migration. It does not change the public identity of an existing app alias by itself. Transport and response bounds The reviewed provider client requires an HTTPS origin outside loopback, rejects credentials and path material, disables authenticated redirects, and uses bounded connection and request behavior. It enforces query, JSON, upload, response, SSE frame, and event limits. Catalogue response kinds select JSON, normalized SSE, or bounded base64 binary output. All non-GET catalogue operations require approval and an AIP idempotency key. Only GET operations publish safe retry support. Streaming and cancellation durability App aliases retain blocking and streaming execution. The reviewed connector adds explicit SSE operations and normalizes event kinds, terminal results, human-input pauses, and provider failures. Remote task identity is stored without destructive read. Cancellation can survive restart through instance-scoped profile state in the standalone host. Missing task identity remains an unconfirmed remote stop. Cancelling an event subscription closes only the local stream and never infers workflow stop. Standalone security boundary The reviewed topology fixes provider origin, descriptors, key files, connector identity, artifact, manifest, tenant, lifecycle route, and credential revision outside Action input. These controls describe reviewed source. They do not qualify an arbitrary Dify deployment or make direct provider calls part of AIP. Deprecated, removed, or renamed No Dify capability is declared deprecated, removed, or renamed in the reviewed range. The operation suffixes and Knowledge domain are additions. Future provider aliases or route removals must not be inferred from upstream names. Record them only when reviewed connector source or release policy defines the change and migration. Apply the required migration | Change encountered | Required action | Do not do | | Bundled connector to standalone host | Preserve tenant, app, key, Action, task, approval, and idempotency evidence through the fleet migration | Run both mutation paths without a fence | | Same version string on a new snapshot | Admit a new immutable connector version with exact source, image, manifest, and release identities | Overwrite an existing record or identify it only as 1.0.0 | | Alias-only manifest expands | Refresh discovery, policy, generated clients, expected counts, and catalogue digest | Construct suffixes from provider route names | | Shared app key becomes scoped | Create owner-only per-app files and bind each descriptor explicitly | Copy one key into unrelated app or Knowledge scopes | | Knowledge is enabled | Add independent workspace descriptors, keys, policy, and 46-capability admission per credential | Reuse an application key | | Durable cancellation is enabled | Provision coherent host storage and preserve instance-scoped profile state | Use process memory as restart-safe evidence | | Response treatment changes | Revalidate bounds, SSE terminal behavior, binary consumers, and uncertainty handling | Infer treatment only from Content-Type | | Upstream revision changes | Re-audit methods, paths, schemas, mode support, and exclusions, then requalify | Promote new provider bytes under the old compatibility claim | Stabilize standalone identity and credential isolation before adopting new Knowledge mutations or a provider upgrade. Retain compatibility pins | Surface | Reviewed pin | | Connector ID | dify | | Connector profile | aip.connector.dify.v1 | | Manifest format | aip-manifest/v1 | | Workspace and host version | 1.0.0 | | Native AIP version | 1.0 | | Dify upstream commit | f8d47616c15d0959f604f6a5e2e1d32d3108991b | | Frozen operation templates | 33 app and 46 Knowledge | | Default provider-response limit | 8 MiB | | Maximum configurable response limit | 64 MiB | | Standalone host | aip-host-dify | | Standalone version-ID shape | cverdify100 | The upstream commit identifies reviewed source, not a built Dify image or deployment. Changing provider bytes does not establish compatibility with the new artifact. Decide when a new connector version is required Create and admit a new immutable connector version when a change affects: • capability IDs, projection, schemas, contracts, kind, risk, approval, retry, idempotency, or compensation; • provider method, path, query, body, multipart, response, event, or status mapping; • descriptor semantics, app mode, credential scope, secret handling, URL policy, health probe, or request bounds; • task-store namespace, task identity, cancellation certainty, stream terminal behavior, or cleanup; • artifact bytes, dependencies, manifest digest, upstream baseline, host lifecycle, or storage behavior. A documentation clarification alone does not require a connector version. It still needs the source revision that proves the corrected statement. Record future entries completely Each future entry should state: 1. release or explicit unreleased status and UTC review date; 2. full source commit, tree, and reconstructable dirty state when applicable; 3. connector, image, manifest, catalogue, release, descriptor, and upstream identities; 4. added, changed, fixed, security-relevant, deprecated, and removed surfaces; 5. caller, operator, storage, credential, and provider migration actions; 6. rollback and compatibility boundary; 7. exact connector, image, fleet, and live qualification result, or notrun; 8. replacement and removal date only when source defines them. Do not reconstruct release history from filenames, mutable tags, or source presence. Mark unknown history as unknown.
