(While PayPal payments will remain available from January 2027 through March 17, 2027, PayPal will no longer provide support in the event of any issues; therefore, we strongly recommend making the switch by December 31, 2026.) We will provide further details, including specific procedures, at a later date.

(While PayPal payments will remain available from January 2027 through March 17, 2027, PayPal will no longer provide support in the event of payment issues; therefore, we strongly recommend switching to an alternative payment method by the end of December 2026.) Additionally, for customers who are setting up payment methods for their e-commerce features, we recommend using Stripe. Please note that procedures such as opening a Stripe account will be available through the learningBOX admin panel following the release of Ver. 7.1 on October 21.

Thank you very much for using learningBOX. Today, learningBOX has been updated to Version 7.0. We would like to introduce the various features that have been added or improved in this update. Enhanced Features: Ability to Set the Default Display Period for Grade Management A feature has been added that allows you to change the default “Display Period” setting for grades in the Grade Management menu. Previously, users had to narrow down the display period each time they navigated to a new screen; however, Owner Administrators and administrators with Grade Management permissions (all users, “Edit” for all content) can now set the default display period between 1 and 60 days to suit their organization’s operations. Once set, this applies across the entire system, and the grades for the selected period will be displayed immediately upon logging in. *For details, please refer to “[Grade Management] Menu Accessible via the Gear Icon.” View Illustrated Guide (PDF) Now You Can Batch Save Diagnostic Test Score Reports as CSV Files! A feature has been added that allows you to batch download detailed diagnostic result data in CSV format from the score reports linked to diagnostic tests. Analysis results for trait tags and evaluation results from the essay panel—which previously could only be viewed on-screen—can now be exported as individual rows of data for each participant, with a maximum of 10,000 records. *For details, please refer to “By Content.” View illustrated materials (PDF) Bulk import of diagnostic test responses (e.g., paper-based) as CSV A feature has been added that allows you to bulk import diagnostic test response data—collected separately via paper or external systems—into the system using a CSV file. Simply download the response import template tailored to the target group, enter the participants’ answer choice numbers, and upload the file to complete the import. Furthermore, based on the imported response data, the system can automatically generate report cards linked to the diagnostic tests. *For details, please refer to “By Content.” View illustrated materials (PDF) Number of learning materials selectable at once in “Progress” expanded to 300 In the “Progress” tab of the Grade Management section, the maximum number of content items that can be selected at once has been significantly expanded to 300. This allows you to view the progress rates and learning status of all learners at a glance in a single, side-by-side list, even for large-scale courses or curricula with a very large number of learning materials. *For details, please refer to “Setting Conditions.” View illustrated guide (PDF) Option added to allow sending emails to users with Grade Management (View) permissions A control option has been added that allows users with Grade Management (View) permissions to send emails, such as grade management notifications and learning progress notifications. When the owner administrator enables this feature in the settings screen, even administrators with “View” permissions can send specific notification emails; if disabled, the menu will be hidden. *For details, please refer to “Settings.” View illustrated documentation (PDF) List of New Features and Improvements For detailed information on the new features and improvements added in this update, including those mentioned above, please review the release notes below. ● Release Notes Announcement: Notice Regarding Some Specification Changes In conjunction with this update, we have made changes to the specifications of some features. ● Addition of a setting to allow email sending with “Grade Management Permissions (View)” ● Change to the email notification frequency in the messaging feature (notify each time) ● Changes to the rich text editor Please review the details via the link below and take the necessary actions as needed. ● [Advance Notice] Notice of Specification Changes Accompanying the Release of Ver. 7.0 Other: For detailed operating instructions or if you have any questions, please contact us using the information below. ● Contact Form We will continue to do our utmost to provide products and services that satisfy our customers.

Thank you very much for your continued use of our services. In conjunction with the release of Version 7.0, scheduled for September 16, 2026, we will be making changes to the specifications of certain features. Accordingly, we would like to inform you of the main changes as follows. Addition of a setting to allow sending emails with “Grade Management Permissions (View)” ■ Affected Features: Grade Management Notifications, Learning Progress Notifications ■ Affected Users: Users with “Grade Management Permissions (View)” ■ Details of the Change: Previously, users with “Grade Management Permissions (View)” could only send “Learning Progress Notifications” from the Group Chart screen and could not send “Grade Management Notifications” from the Grade Management screen. Starting with the release of Ver. 7.0, the ability to send email notifications related to grades (Grade Management Notifications and Learning Progress Notifications) will be subject to administrator approval. *Feature scheduled for release in Ver. 7.0 Comparison of settings before and after the change Permission Setting Grade Management Notifications Learning Progress Notifications Before Change Cannot be sent Can be sent After Change Off *Default setting Cannot be sent Cannot be sent On Can be sent Can be sent ■Request to Customers: After the release of Ver. 7.0, the permission will be set to “Off” by default. Therefore, if users currently holding “Grade Management Permissions (View)” are sending Learning Progress Notifications, they will no longer be able to do so without further action. If you need to continue sending these notifications, please change the permission setting to “On” in the settings screen after the release of Version 7.0. Setting it to “On” will enable the sending of grade-related notifications (Grade Management Notifications and Learning Progress Notifications). Change to Email Notification Frequency for the Message Feature (Notifications Sent Each Time a Message Is Sent) ■ Affected Feature: Message Receipt Notifications ■ Details of the Change: We are changing the specification so that notification emails—which previously were sent once a day, aggregating unread messages—will now be sent each time a message is sent. Comparison of Before and After the Change Before the Change: A notification email was sent once a day (around 12:00 JST) to users with unread messages. After the Change: A notification email will be sent each time a message is sent. ■ Important Notes and Request to Customers (Regarding the Period During Which Notification Emails Will Not Be Sent) Due to migration processes associated with this specification change, notification emails will not be sent for messages sent during the following period. Affected Period: Around 12:00 on September 15, 2026 – Around 6:30 on September 16, 2026 (Until the Ver. 7.0 update is complete) Since unread notification emails will not be sent for messages sent during the above period, we kindly ask that you check the message function directly within the system. We apologize for any inconvenience this may cause to our users and appreciate your understanding and cooperation. Changes to the Rich Text Editor ■ Affected Feature: Rich Text Editor ■ Details: We will be replacing the editor (TinyMCE) used in text input and editing screens throughout the system with a new editor (Froala). Scope: Creation, editing, and submission screens for all major features, including quizzes and tests, reports, web pages, flashcards, and other learning materials. Comparison Before and After the Change Before: Old Editor (TinyMCE) (Example) Quiz/Test Material Editing Screen After: New Editor (Froala) (Example) Quiz/Test Material Editing Screen ■Impact ① Screen Design and Usability: Due to the editor switch, the UI design, toolbar icon layout, and some aspects of usability will change. ② Display of Existing Content: If you continue to use existing content as-is after the update, there will be no changes to how it appears. However, if you edit and save content created with the old editor after the update, the internal HTML will be converted to the new editor’s format, so the display layout may change slightly. ■ Request to Customers: Since the placement of the toolbar and other elements will change on the administrator screen, we ask that you consider updating your internal manuals and guidelines as necessary. Additionally, please consider creating a backup before editing important content. After the update, please check to ensure there are no issues with the display or layout. We apologize for any inconvenience this may cause our users and appreciate your understanding and cooperation.

With the addition of this new feature, the CSV export specifications have been partially updated, and a new “Action” column has been added. By entering “add” (to add) or “delete” (to remove) in this column, you can specify the action for each row.

Thank you very much for using learningBOX. Today, learningBOX has been updated to Version 6.1. We would like to introduce the various features that have been added or improved in this update. Enhanced Features: Smoother Configuration and Verification from the Content Management Screen With this update, you can now see at a glance whether “Content Assignments,” “Course Expiration Dates,” and “Publication Periods” have been set and how many entries exist in the Content Management screen.

On the other hand, for group assignments, selecting a parent group applies a check mark to all its child groups. In this way, affected and unaffected elements are clearly distinguished by color and other visual cues, helping to prevent unexpected configuration errors—such as “I thought I set it up, but it wasn’t assigned”—before they occur. *For details, please refer to “Bulk Settings (Content Assignment Management).” View illustrated guide (PDF) Email notifications for unread messages are now sent once a day! With this update, notifications for unread messages in all rooms have been changed to be sent once a day in a single batch.
