| 7 | +--- |
| 8 | + |
| 9 | +The next release is centered on one theme: faster paths from existing data to realistic, constrained, exportable test sets. |
| 10 | + |
| 11 | +This release adds broader combinatorial generation, schema authoring improvements, better import/export controls, and a few high-value grid usability upgrades. |
| 12 | + |
| 13 | +<!-- truncate --> |
| 14 | + |
| 15 | +## 1. N-wise combinatorial generation, not just pairwise |
| 16 | + |
| 17 | +The biggest addition is that combinatorial generation now goes beyond pairwise. |
| 18 | + |
| 19 | +Instead of stopping at 2-wise coverage, you can now choose stronger coverage levels for enum-driven schemas and compare strategies before generating. |
| 20 | + |
| 21 | +Example schema: |
| 22 | + |
| 23 | +```text |
| 24 | +Browser: Chrome,Firefox,Safari |
| 25 | +Device: Desktop,Tablet,Mobile |
| 26 | +Locale: en-GB,en-US,fr-FR |
| 27 | +Theme: Light,Dark |
| 28 | +``` |
| 29 | + |
| 30 | +With this schema you can choose: |
| 31 | + |
| 32 | +- `2-wise` to cover every pair of enum values |
| 33 | +- `3-wise` to cover every triplet |
| 34 | +- stronger levels when you need more interaction coverage |
| 35 | + |
| 36 | +This is especially useful when pairwise is too light, but full Cartesian generation would explode the row count. |
| 37 | + |
| 38 | +Docs: |
| 39 | + |
| 40 | +- [N-Wise Testing](/docs/test-data/n-wise-testing) |
| 41 | +- [Pairwise Testing](/docs/test-data/pairwise-testing) |
| 42 | + |
| 43 | + |
| 44 | + |
| 45 | +## 2. Schema constraints with PICT-style `IF ... THEN ...` |
| 46 | + |
| 47 | +Schema constraints make generated combinations more realistic by filtering out invalid rows. |
| 48 | + |
| 49 | +Example: |
| 50 | + |
| 51 | +```text |
| 52 | +Priority |
| 53 | +enum("High","Medium","Low") |
| 54 | +Status |
| 55 | +enum("Open","Queued","Closed") |
| 56 | +Escalated |
| 57 | +enum("Yes","No") |
| 58 | +
|
| 59 | +IF [Priority] = "High" THEN [Status] = "Open"; |
| 60 | +IF [Priority] IN {"High","Medium"} THEN [Escalated] = "Yes"; |
| 61 | +``` |
| 62 | + |
| 63 | +This means: |
| 64 | + |
| 65 | +- high-priority items must be open |
| 66 | +- high and medium priorities must be escalated |
| 67 | + |
| 68 | +Constraints work well with enum-heavy decision tables and combinatorial generation, giving you more realistic output without manually cleaning results afterward. |
| 69 | + |

| 73 | + |
| 74 | +## 3. Grid to Enum Schema for turning existing tables into generators |
| 75 | + |
| 76 | +If you already have representative data in the main grid, you can now turn that grid into an enum schema automatically. |
| 77 | + |
| 78 | +Example grid: |
| 79 | + |
| 80 | +```text |
| 81 | +Browser,Device,Theme |
| 82 | +Chrome,Desktop,Light |
| 83 | +Firefox,Mobile,Dark |
| 84 | +Chrome,Tablet,Dark |
| 85 | +``` |
| 86 | + |
| 87 | +Generated schema: |
| 88 | + |
| 89 | +```text |
| 90 | +Browser |
| 91 | +enum("Chrome","Firefox") |
| 92 | +Device |
| 93 | +enum("Desktop","Mobile","Tablet") |
| 94 | +Theme |
| 95 | +enum("Light","Dark") |
| 96 | +``` |
| 97 | + |
| 98 | +This is one of the most practical workflow improvements in the release because it shortens the path from imported examples to reusable generation rules. |
| 99 | + |

| 102 | +- [Data Grid Editable](/docs/test-data/data-grid-editable) |
| 103 | + |
| 104 | + |
| 105 | + |
| 106 | +## 4. PICT-style inline enum definitions such as `Name: values` |
| 107 | + |
| 108 | +Schema text now fits more naturally with compact PICT-style authoring. |
| 109 | + |
| 110 | +Example: |
| 111 | + |
| 112 | +```text |
| 113 | +Browser: Chrome,Firefox,Safari |
| 114 | +Theme: Light,Dark |
| 115 | +Priority: enum("High","Medium","Low") |
| 116 | +Owner: person.fullName |
| 117 | +``` |
| 118 | + |
| 119 | +That means you can mix: |
| 120 | + |
| 121 | +- raw inline enum values |
| 122 | +- explicit `enum(...)` |
| 123 | +- other command-based field definitions |
| 124 | + |
| 125 | +This makes it easier to paste or adapt schemas from existing combinatorial models instead of rewriting them into a stricter two-line format. |
| 126 | + |
| 127 | +Docs: |
| 128 | + |
| 129 | +- [Schema Definition](/docs/test-data/Schema-Definition) |
| 130 | + |
| 131 | +## 5. Import trimming controls for cleaner amend and import workflows |
| 132 | + |
| 133 | +Imported files and clipboard data can now be normalized during import. |
| 134 | + |
| 135 | +You can trim: |
| 136 | + |
| 137 | +- every imported field value |
| 138 | +- only selected fields |
| 139 | + |
| 140 | +Example selected fields list: |
| 141 | + |
| 142 | +```text |
| 143 | +Name, Email |
| 144 | +``` |
| 145 | + |
| 146 | +This helps when imported files contain accidental whitespace around values, but you do not want to aggressively rewrite every column. |
| 147 | + |

| 151 | + |
| 152 | + |
| 153 | + |
| 154 | +## 6. File export settings for line endings and BOM |
| 155 | + |
| 156 | +Downloads now support file transport settings without changing the preview text shown in the browser. |
| 157 | + |
| 158 | +You can configure: |
| 159 | + |
| 160 | +- `LF` or `Windows (CR/LF)` line endings |
| 161 | +- optional UTF-8 `BOM` |
| 162 | + |
| 163 | +This is useful when exporting for spreadsheets, Windows tooling, or downstream systems that are sensitive to file encoding details. |

| 170 | + |
| 171 | +## 7. Right-click context menu in the main data grid |
| 172 | + |
| 173 | +The editable grid now has a right-click context menu for common grid actions. |
| 174 | + |
| 175 | +This keeps more of the workflow close to the current selection and makes the app feel more like a direct data-work surface rather than a form with a grid attached to it. |
| 176 | + |
| 177 | +Docs: |
| 178 | + |
| 179 | +- [Data Grid Editable](/docs/test-data/data-grid-editable) |
| 180 | + |
| 181 | +## 8. Always-visible total row counts in the data grid |
| 182 | + |
| 183 | +The main grid now shows total row counts, and filtered views also show how many rows remain visible. |
| 184 | + |
| 185 | +Examples: |
| 186 | + |
| 187 | +```text |
| 188 | +Total rows: 125 |
| 189 | +``` |
| 190 | + |
| 191 | +```text |
| 192 | +Total rows: 125 | Filtered Visible: 12 |
| 193 | +``` |
| 194 | + |
| 195 | +It is a small change, but it removes friction during import checks, filtered analysis, and post-generation review. |

| 200 | + |
| 201 | +## Why should you care? |
| 202 | + |
| 203 | +Taken together, these features make the tool better at moving through the whole workflow: |
| 204 | + |
| 205 | +1. start with imported or hand-edited data |
| 206 | +2. convert it into a schema |
| 207 | +3. add constraints |
| 208 | +4. generate the right amount of combinatorial coverage |
| 209 | +5. export in the format and file encoding you actually need |
| 210 | + |
| 211 | +The release adds more generation power, reduces setup time, and cleanup time around that generation. |
