Core Releases

2026.04.07.15

Created a Builder MCP Server (located at https://{yourtenant-test-env-domain}.flowgear.net}/mcp/builder that enables creation of Workflows directly from your favorite IDE and agent
Added support for GROUPBY function in expressions - use this function at the container level to define groupings, paired with aggregator functions like SUM or MAX
Added automatic inference of return property schema (and sample values where available) after a Workflow is debug-invoked. This saves manually defining a schema for generic Nodes where schema can't be statically determined
Added automatic preview of parameter sample values by projecting returns from prior Steps (shows the effect of an expression on sample data so it's easier to confirm that your expression is correct)
Enhanced handling of v2 Connections
Added support for complex (multi-property) return values on Nodes
Added ability to mark Nodes as obsolete which causes them to be hidden from the Add Step list in the designer
Multiple improvements to type system
Fixed issues affecting sub-workflow invoke routing between cloud and local Clusters
Fixed an issue that was causing local Runtimes to get stuck in a continuous reconnect loop
Improved error messages for version control infra (Azure Basic and GitHub)

2026.03.12.10

Fixed DateTime strings incorrectly converted to DateTimeOffset objects in MessageHub

Fix issue where certain types were incorrectly logged
Add support for multiple return values on Nodes
Strengthen trigger node compile-time validations
Create installers and chrome to manage local runtimes

Add large value logging support
Add scheduler support to workflows
Add runtime support for many type conversion permutations
Adjust cluster management controllers to support local runtimes

2026.01.12.20

Release notes now relate to v2 runtime unless stated otherwise.

Added

Added assistant LogTools to list workflow logs (with optional step range) and retrieve a specific log entry, returning trimmed YAML for assistant consumption.
Added an HTTP MCP Trigger node that exposes MCP invocation details (method, URI, headers, parameters, and arguments) to workflows.
Added the Acumatica OpenAPI connector with operation execution and template discovery for available actions.
Added the ConnectWise Manage connector with OpenAPI-based operations and template discovery support.
Added the Microsoft OneDrive connector for listing drives/items, creating folders, uploading items, and more; uploads are performed via upload sessions for large files.
Added the Oracle NetSuite REST connector with query/mutation operations and template discovery for OpenAPI actions.
Added the PaySpace connector with query/mutation/delete operations, plus documented response normalization and built‑in paging guidance for users.
Added a generic GraphQL Request connector that validates queries against schema metadata and supports query/mutation templates.
Added a Shopify GraphQL connector with query/mutation operations, schema-aware variable normalization, and automatic cursor-based pagination for responses.
Added an XML Document processor that parses XML into JSON and streams XML document creation from JSON items.
Added local file operations and remote FTP/FTPS/SFTP file operations as dedicated File connectors (read/write/copy/move/delete/info).
Added/updated the Microsoft SQL connector implementation for query/upsert/watcher operations using Microsoft.Data.SqlClient.
Added the SAP S/4HANA connector with explicit query/create/update/delete actions based on OpenAPI templates and connection validation.

Changed

Expanded the assistant prompt with detailed workflow authoring guidance, tool parallelization rules, and an explicit debug flow that uses LogTools after invocation failures.
Updated WebRequest methods to accept streamed request bodies and return streaming HTTP responses across HTTP verbs (GET/POST/PUT/etc.).
MCP tool responses now emit structured content (JSON) and incorporate runtime response context when available, improving client-side handling of tool results.
GraphQL query validation uses schema-aware checks to produce variable metadata, enabling more predictable template and variable handling.

Fixed

Workflow ForEach rendering now tracks async enumerator state and projection management for safer iteration behavior in generated workflows.
Runtime type conversion now explicitly handles JsonNode and IAsyncEnumerable conversions to improve parameter binding stability for node executions.

Performance

LogTools shapes log payloads with capped previews and trimmed content to reduce response size when diagnosing workflow runs.
