## **Detailed Version**

{% tabs %}
{% tab title="🅱️ Bug Fix" %}

* #### MateDrive Large File Download Gateway Timeout Issue

  Downloading large files from MateDrive could cause Gateway Timeout errors and make the environment temporarily inaccessible.

  Large file download handling has been improved to preserve platform availability, reduce timeout risk, and provide safer behavior during file transfer failures.

***

* #### Else Condition Missing from Logs

  When a workflow executed an Else branch and later failed, the Else condition step was not always displayed in the logs.

  Executed Else condition branches are now shown correctly in the log list, helping users understand which path was followed during troubleshooting.

***

* #### Empty Logs Summary Screen for Failed Operations

  The Logs Summary screen could appear empty for failed operations even when execution steps were available.

  Logs Summary behavior has been corrected so executed steps remain visible and failure analysis can be performed accurately.

***

* #### Elasticsearch Retry Continues After Summary Screen Closure

  The Summary screen retry mechanism for Elasticsearch continued running even after the user closed the screen or navigated away.

  Retry lifecycle handling has been updated so retry processes are cancelled when the Summary screen is closed, preventing unnecessary background requests and resource usage.

***

* #### Gateway Rate Limiter Nil Pointer Crash

  The gRPC gateway service could crash with a SIGSEGV error due to nil memory information handling in the AdjustRateLimiter function.

  Nil checks and safer locking behavior have been added to prevent gateway crashes and improve service stability in ECS/Docker environments.

***

* #### MateDrive Delete Action Internal Error Exposure

  The MateDrive Delete action could expose internal stack traces and source references when the file name was null or empty.

  Validation has been added so missing file names now return a clear user-friendly error instead of exposing internal technical details.

***

* #### Backend Crash During High-Volume Log Search

  The backend could crash when users searched large log datasets using the top search bar together with multiple filters.

  Log search handling has been optimized to prevent crashes and improve stability when filtering high-volume log data.

***

* #### Variable Type Change to Date Error

  Changing a variable from another format, such as Array, to Date could cause errors because the default value was not handled properly.

  Variable type switching behavior has been improved to handle Date conversion scenarios more safely.

***

* #### Incorrect Total Elapsed Time in Monitoring

  Monitoring could show an incorrect total elapsed time in summary information, even though the internal Autom end time data was correct.

  Elapsed time calculation and display behavior have been corrected to ensure Monitoring shows accurate execution duration.
  {% endtab %}

{% tab title="✨ New Features" %}

* #### Low-Resource MateDrive Upload Service

  A new MateDrive upload service has been introduced to reduce resource consumption during file upload operations.

  The service is designed to use streaming or chunk-based processing, preventing large files from being fully loaded into memory and improving stability during large uploads.

***

* #### Stop Action Response Header Support

  The Stop action now supports a new Response Header section.

  Users can define response headers in key-value format for API-triggered Hyper Flow executions, allowing custom headers to be returned together with response body, status code, and response type.

***

* #### Multipart/Form-Data Trigger Payload Parsing

  Autom Mate can now parse multipart/form-data trigger requests into usable trigger data.

  Form fields and file metadata can now be converted into structured trigger data and used as variables inside workflows.

***

* #### App Library OAuth Basic Auth Header Support

  App Library authentication now supports OAuth client\_credentials flows where client authentication is sent through the Basic Auth Header.

  This enables integrations such as Fiserv to retrieve access tokens using Authorization: Basic header authentication while preserving existing authentication methods.

***

* #### Array Library Merge Arrays Action

  A new Array library action has been added to merge two arrays into a single output array.

  The action accepts two array inputs, preserves order, and returns a combined array output for use in Hyper Flow workflows.

***

* #### Failed Operation Rerun Mechanism

  A new rerun mechanism has been introduced for failed operations.

  Users can rerun eligible failed operations by selecting either the Active version or Dev version. Each rerun creates a new linked operation, keeping the original operation traceable in Monitoring.
  {% endtab %}

{% tab title="🛠️ Enhancements" %}

* #### New Design System for Legacy Management Pages

  Legacy management pages have been updated to align with the current Autom Mate design system.

  The updated pages include Alerts, Queue, Custom Credentials, and Webhook API, improving UI consistency while preserving existing functionality.

***

* #### Product-Wide Terminology and Navigation Naming Updates

  Module, menu, and screen names have been reviewed and updated to better align with the current product language.

  This includes terminology improvements for Libraries, Apps, Market-related navigation, and Dashboard Summary Mail placement and naming.

***

* #### Product Page Descriptive Texts

  Descriptive texts have been added to product pages to help users understand the purpose and usage of each module.

  These descriptions improve onboarding, module discoverability, and overall user guidance across the platform.

***

* #### “Automs” Renamed to “Hyper Flow”

  The term “Automs” has been replaced with “Hyper Flow” across the product.

  This update applies to sidebar navigation, creation modals, page titles, breadcrumbs, buttons, empty states, help texts, notifications, and related UI components.

***

* #### Monitoring Terminology Update

  Monitoring references such as “Autom History” have been updated to “Execution History.”

  This change supports the broader Hyper Flow terminology transition and improves clarity in execution-related screens.

***

* #### Gateway Performance and Resource Optimization

  Gateway project performance has been improved through RAM and CPU optimization.

  The optimization focuses on setVariable flow behavior, Object and Array library operations, repetitive execution paths, and high-volume workload stability.

***

* #### Library Version List Performance Improvement

  The library version list screen has been optimized to reduce excessive data loading.

  Data fetching behavior has been improved through better listing strategy, reduced unnecessary transfer, and support for more stable performance in large dataset scenarios.
