- New Group frame
Tick "まとめ枠" (group frame) in a box's properties to turn it into a frame that encloses the boxes placed inside it (e.g., a P-EFP grouping several latent experiences). Moving the frame moves the boxes and notes inside it as well. - New Show or hide connection points
Use "接続点" (connection points) on the 表示 (View) tab to hide the small circles on the left and right of each box. Arrows can still be connected while they are hidden, and they never appear in exports (PPTX, SVG, PNG, PDF). - Fixed Your work is kept when the app stops with an error
When the error screen appears, the current diagram is saved to the auto-backup right away. After reloading, choose "OK" (restore) to get it back. The error screen also lets you save the diagram as a .tem file and copy the error details.

- Improved Text after a symbol
After choosing a symbol from the note's symbol palette, you can keep typing after it, as in "★ Turning point". - Fixed SD/SG disappearing in multi-page exports
When exporting PPTX or SVG across several pages, SD/SG attached to arrows, and wide SD/SG whose two boxes fall on different pages, were missing. This has been fixed.

- New Import TEM diagrams drawn in PowerPoint
Choose a .pptx file from "表から取り込み" (import from table) on the ファイル (File) tab, and TEMer rebuilds boxes, arrows, SD/SG and period labels from the shapes and their positions. PPTX files exported by TEMer come back as they were. - New Emphasis symbols (★, 〇, etc.)
Use "記号" (symbol) on the 挿入 (Insert) tab to place a text-only note with no background or border. The text color can be changed. - Fixed PowerPoint export: mismatched box and text sizes, broken paragraph settings
Text size, font, line spacing and margins now match the screen, so even complex diagrams look the same as in the app. - Fixed Shape and direction of SD/SG
SD/SG in SVG and PPTX are now the same pentagon as on screen, and their direction in vertical layouts matches the screen. Overlapping type labels and sublabels have also been fixed. - Improved SVG text wraps as on screen
Text in boxes, SD/SG and notes now wraps at the same points as on screen. - Fixed Connection-point circles appearing in PNG and PDF exports
- Improved Period label settings
Rows no longer jump while you are typing, and the range of each period is shown when periods are displayed as bands. - Fixed Garbled transcript CSV files
CSV and text files saved in Shift_JIS can now be read.
September 25, 2026
- New Table import wizard and MAXQDA import
Import CSV or Excel files as boxes, arrows, SD/SG, period labels or transcripts by choosing the role of each column. Coded segments exported from MAXQDA 24 are also supported.
September 21, 2026
- New Notes
Place interpretations and comments on the diagram as sticky notes. - New Wide SD/SG
An SD/SG can span two boxes and draw arrows to the boxes it affects.
September 20, 2026
- New Overlap check
Use "重なりチェック" (overlap check) on the 整理 (Arrange) tab to list overlapping boxes, arrows, SD/SG and labels. - New Combined types and the "Other" type
A box can show two types together, such as "bifurcation point and obligatory passage point". - Improved Edit labels with Enter / F2
Press Enter or F2 to edit the text of the selected box, SD/SG or legend right away. - Improved Create boxes from Excel or text rows
The insert button on the data sheet turns each pasted row into a box. - Improved Default arrow style
Set the default arrow style in the settings dialog and apply it to all arrows. - Fixed Long vowel mark "ー" shown sideways in vertical SVG text
