Release: 1.1.0 [2022-09-07]
| Feature Bug Fix | Description | Comments |
|---|---|---|
| Feature | Removed API to save pebble output as an Excel spreadsheet. | This feature was ill-placed in the runtime. We will release runtime-utils shortly to contain this and other functionality. |
| Bug Fix | Pebble Stream runtime did not compute if statements without an else condition | Compiler and analyzer both accept if statements without else conditions. |
Release: 1.0.1 [2022-07-28]
| Feature Bug Fix | Description | Comments |
|---|---|---|
| Bug Fix | Fix >= and <= detection in filter directive compilation | The analyzer sometimes fails to pick up the filter directive's greater and less than equal signs. This release fixes this issue. |
| Bug Fix | Convert new smart quote character to canonical quote during compilation. | Some spreadsheet implementations use different characters for quoting. This release recognizes more of those characters as quotes. |
| Bug Fix | Return nil always when looking past the length of a previously computed sheet. | In certain circumstances, the runtime will revert to template values if it detects that the input sheet is not provided. This behavior has been corrected. |
