There are three important features that were in the initial design of D2 that have not been done and hold it back from 1.0: globs, imports, and vars. This release brings imports.
Imports open up a world of possibilities and works beautifully to modularize diagrams. See the new docs to try it out today.
As usual, many improvements and bug fixes accompany this release. D2 0.5 produces more legible diagrams by masking obstructions (e.g. arrow going through a label), has better error messages to guide you, is faster at certain tasks, and addresses many issues brought by community bug reports.
- D2 files have the ability to import from other D2 files. See [docs](https://d2lang.com/tour/imports). [#1371](https://github.com/terrastruct/d2/pull/1371)
-`sql_table` alternatively takes an array of constraints instead of being limited to a single one. Thanks @satoqz ! [#1245](https://github.com/terrastruct/d2/pull/1245)
- Constraints in `sql_table` render even if they have no matching abbreviation [#1372](https://github.com/terrastruct/d2/pull/1372)
- Constraints in `sql_table` sheds their excessive letter-spacing and is padded from the end consistently [#1372](https://github.com/terrastruct/d2/pull/1372)
- Duplicate image URLs in icons are only fetched once [#1373](https://github.com/terrastruct/d2/pull/1373)
- In watch mode, images are cached by default across compiles. Can be disabled with flag `--img-cache=0`. [#1373](https://github.com/terrastruct/d2/pull/1373)
- Invalid `constraint` usage is met with an error message, preventing a common mistake of omitting `shape: sql_table` [#1379](https://github.com/terrastruct/d2/pull/1379)
- Fixes fonts not rendering correctly on certain platforms. Thanks @mikeday for identifying the solution. [#1356](https://github.com/terrastruct/d2/pull/1356)
