ChangeLog

The current DataFlux Func version is 8.x. All previous versions have been archived and are available for download only; they are no longer updated or supported.

8.0.27 (2026-08-15)

  • Enhanced multi-user and multi-tab editing conflict detection: the server continuously tracks the page where the client is located, actively syncs state among different clients and multiple Server nodes, and promptly releases occupancy of pages that have been left, avoiding missed conflicts or stale state updates in scenarios such as Script editing, Connector and environment variable settings, and Script Market management.
  • Optimized the graceful shutdown and restart process for Server and Worker, closing MCP sessions, Web and Socket.IO services, system database connections, and worker processes before exit, and adding timeout and forced-exit fallbacks to reduce process hangs and connection residue.
  • Added the X-Dff-Cache: Cached header to cached responses for health checks, system overview, system report, latest network test, and the Script Lib sidebar, making it easier to identify cache hits.
  • Optimized image and Connector Logo display under dark themes, preserving the original colors of Connector Logos, and adjusted the message top spacing, notification bar height, and quick-view window position.

8.0.26 (2026-08-13)

  • Optimized the sidebar loading and refresh for large Script Libs, using Redis shared cache, data MD5, and independent draft state updates to reduce duplicate queries, data transfer, and directory tree rebuilding, and falling back to real-time reads when the cache is abnormal.
  • Improved the editor responsiveness for large Script Libs by rendering Script node details on demand, narrowing the autocomplete scan scope, loading Script ID completion only in import statements, and optimizing candidate deduplication.
  • Optimized frontend large-data page performance by merging and briefly caching function selector requests, limiting the initial rendering volume of dropdown options, batching function documentation and system logs, initializing system metric charts on demand, and pausing auto-refresh on hidden pages.
  • Improved Script Market management prompts: the publish preview marks unpublished drafts and clarifies that the official version will still be published, while distinguishing management conflicts caused by other users, other tabs, or other browsers.
  • Fixed an issue where version and list refresh states were overwritten between multiple tabs, allowing each tab to detect upgrade notifications independently and preventing old page states from reverting newly loaded version information.
  • Optimized the reporting of local function and Connector lists via the data platform WebSocket, using database change summaries and shared data snapshots to reduce duplicate queries, and preventing stale connection acknowledgments from updating new connection states.
  • Fixed an issue where the page errored when the example parameters of a Func API call were empty.

8.0.25 (2026-08-12)

  • Optimized the system information API and login state synchronization, returning only the configuration required by the page based on login status, preventing exposure of internal information such as hosts, directories, queues, and data platform nodes when not logged in, and cleaning up or restoring corresponding states on login failure.
  • Fixed system settings caching and custom site icon handling: settings changes take effect immediately, icon responses disable caching and validate the image type, and invalid configurations fall back to the default icon.
  • Improved the stability of data platform WebSocket event subscriptions, enhancing reconnection on authentication failure, Ping timeout, isolation of old authentication callbacks, event data validation, acknowledgment errors, and local data retry handling, and masking call parameters, request bodies, and response details.
  • Optimized disconnect handling for the system MySQL connection pool, gracefully closing idle connections, retrying safe read-only queries once after transient connection errors, and avoiding direct service restarts due to connection errors.

8.0.24 (2026-08-11)

  • Optimized the Script Market change preview, displaying the Scripts and their Script Sets to be added, modified, or deleted in a table, and showing the corresponding remote release notes when installing, reinstalling, and upgrading.
  • Strengthened concurrent and exception protection for Script Market operations, adding an independent renewable lock for Git repository operations, aborting related processes when the lock is lost, retaining existing files when downloads fail, and avoiding persistence of repository credentials in local Git configuration.
  • Unified the SQL formatter and SQL Builder behavior between Server and Worker, improved validation for time zones, placeholders, object field order, JOIN, pagination, and LIMIT, and fixed parameter handling in Connectors such as MySQL, PostgreSQL, Oracle, SQL Server, ClickHouse, and InfluxDB.
  • Fixed issues with Redis connection readiness, scanning and batch read errors, atomic lock renewal, and time-series range handling, as well as Kafka publish/subscribe, MQTT shared subscription, Socket.IO Redis adapter, and DingTalk bot error response handling.

8.0.23 (2026-08-09)

  • Added support for loading YAML configuration fragments via include in the configuration file config.yaml, using files, directories, or wildcards and merging them in configuration order and by file name; user configuration files and environment variables can still override the configuration; the system report also records the source of each configuration item.
  • Optimized the MCP configuration instructions for access tokens, displaying transport method, URL, HTTP Header, JSON configuration examples, and corresponding documentation links according to MCP Coding and MCP Func modes, and disabling the configuration entry when no feature is enabled.
  • Improved the reliability of DQL-like queries for SQL-type Connectors, fixing issues with time column identification, default time range, result conversion, and escaping and query result handling in different databases.
  • Fixed issues with Redis database number 0, atomic lock renewal, and latest time-series data queries, as well as MQTT publishing, reconnection, and timeout handling.
  • Improved querying, result conversion, and connectivity check handling for Connectors such as MongoDB, Prometheus, NSQ, Memcached, and DataKit.
  • Tightened the visibility scope of some internal help documentation in MCP Coding.
  • Optimized disabled button visibility, notification bar text alignment, and external documentation link display.

8.0.22 (2026-08-06)

  • Added an LLM Connector compatible with the OpenAI Chat Completions API, supporting configurable Base URL, API Key, and model; you can use DFF.CONN() to initiate non-streaming text conversations, and it supports loading or manually selecting models
  • Added a Script code diff preview before publishing, installing, reinstalling, or upgrading in the Script Market. The previewed version is validated during the operation; after publishing or installing, code consistency is verified and repaired or alerted when necessary.
  • Added mutual exclusion and multi-client conflict handling for Script Market management operations; conflicting Script publishing and editing are disabled during operations to prevent concurrent modifications.
  • Optimized the queue card status display on the overview page, using status dots, borders, and queue number colors to distinguish normal, warning, and error states, and highlighting queues with no Worker listening or load approaching saturation.
  • Strengthened the default confirmationHint of MCP Func, clarifying that the AI Agent must obtain explicit user confirmation before invoking a tool.
  • Optimized the color contrast of disabled links.

8.0.21 (2026-08-05)

  • Added the mcp_annotations parameter to DFF.API, which supports declaring read-only, destructive, idempotent, external access, and pre-invocation confirmation hints for MCP tools, and returns related metadata in Func query results.
  • Optimized the development sidebar action bar, unifying the refresh and add entries for Script, Connector, and environment variable lists, and added a collapse-all action for the Script list.
  • Optimized the selected-state colors of the MCP Coding permission mode in access tokens and the height of the notification bar.
  • Enhanced exception handling for Redis task response subscription, masking and logging domains in connection errors to prevent unhandled error events from affecting service stability.

8.0.20 (2026-08-04)

  • Added a personalization settings page, where you can centrally configure language, light/dark mode, UI color scheme, and code editor theme, font size, and line height; settings are saved in the current browser.
  • Added a 'High Contrast' UI color scheme, supporting both light and dark modes.
  • The function task record list now supports exporting all JSONL data based on the current filter conditions.
  • Member selection in Script and Script Set lock configuration now supports searching by username, name, email, and mobile phone number.
  • Optimized the settings page for integrated login users, supporting viewing read-only user profile, using personalization and cache clearing features, and clearly indicating that passwords must be changed in the source system.

8.0.19 (2026-08-03)

  • Optimized the text and background contrast of the code editor search box in light and dark themes.

8.0.18 (2026-08-03)

  • Added Cron Job queue capacity prediction to the overview page. Based on the actual execution queues, running duration, and 7-day average trigger counts of recently completed tasks, it estimates process requirements, queue saturation, and Worker requirements, and alerts when forecast usage reaches half or saturation.
  • Added the dual-color themes 'Unit-01 Purple/Green' and 'Unit-02 Red/Orange', and optimized the colors and contrast of all light/dark themes and interfaces such as the notification bar.
  • Added _DFF_FUNC_CATEGORY, _DFF_FUNC_TAGS, _DFF_FUNC_API_TAGS, and _DFF_CRON_JOB_TAGS to the Script runtime context; child tasks will continue to inherit Func API and Cron Job tags.
  • Added an alert on the overview page for inconsistent versions of running services, distinguishing between error and warning states.
  • Refactored the custom data interface of DFF.SELF_MONITOR_DATA to use add_custom_metric() and add_custom_log() for reporting metrics and logs respectively, with support for custom timestamps, and removed the original add_more_data() interface.
  • Optimized the Cron Job statistics cache on the overview page to reduce duplicate queries and prediction calculations.

8.0.17 (2026-07-30)

  • Global search now supports using @Script Set or Script ID code keyword to limit the code search scope, and * wildcards can match a Script Set or Script ID.
  • Optimized the network test tool: when no protocol and port are specified, it tests HTTP, HTTPS, TCP 80, and TCP 443 simultaneously, displays results by the actual Worker host and its listening queues, and improves the layout of error, duration, and status information.
  • Added the most recent task execution duration to the Func API and Cron Job lists, and added a refresh action to the task record list.
  • Optimized the MCP Coding Script caching and publishing verification process, uniformly using .py files to cache drafts, and after publishing, checking the publishing status through codeMD5 and codeDraftMD5.
  • Removed the hardcoded /bin/bash in Shell Script to improve compatibility when Bash is installed in other paths.

8.0.16 (2026-07-29)

  • Added a not_exists parameter to the Tag and Field setting methods of DFF.SELF_MONITOR_DATA, supporting writes only when the key does not exist.
  • Fixed an issue where configuration placeholders in function call parameters were passed to the running function, preventing parameters not provided by the caller from overriding function default values.
  • Fixed an issue where DFF.FUNC_API.get() could not correctly parse dynamic values in additional configuration when reading a Func API.
  • Fixed validation issues in the HTTP Auth user configuration form: new users must fill in a password, usernames cannot be duplicated, and existing usernames cannot be modified.

8.0.15 (2026-07-29)

  • Reverted Docker Stack host network configuration changes, restored the external bridge network and Sidecar default address 172.17.0.1, and revoked automatic migration of existing Sidecar Connector addresses.
