v1.7.0 - Hello YAML
A major change to CatDat has been introduced in #164: all categorical data is now authored via YAML files. Each category now has its own YAML file, making the data much easier to maintain. The SQL database is still used for processing and querying data. See the PR description for details.
The redundancy check script developed in #155 makes it easy to determine which property assignments are actually necessary.
Features 🧪
- Add Redundancy Tests by @ScriptRaccoon in #155
- Create list page of lemmas by @ScriptRaccoon in #166
Infrastructure 💻
- Separate assignment of dual categories by @ScriptRaccoon in #157
- Fix update script by @ScriptRaccoon in #159
- Record schema changes by @ScriptRaccoon in #161
- Use IDs to order tags, special objects, and special morphisms by @ScriptRaccoon in #165
- Input all categorical data via YAML files by @ScriptRaccoon in #164
Database 🔋
- Add the category of semigroups by @ScriptRaccoon in #158

v1.6.0 - Three major updates
Infrastructure 💻
- Use local SQLite database by @ScriptRaccoon in #138
This is a major change. The SQLite database of CatDat is no longer hosted remotely on Turso, but is shipped directly with the application. This is possible because it is read-only at runtime. Among other things, this provides a significant performance boost for the web application (search + comparison) and simplifies the deployment process. See the PR description for details.
Features 🧪
- Support LaTeX macros by @ScriptRaccoon in #152
This makes writing LaTeX much easier.
Database 🔋
- Add the category of torsion abelian groups by @ScriptRaccoon in #150
- Has effective (co)congruences properties by @dschepler in #126
The PR on effective (co)congruences was a massive effort. It introduces many interesting results and non-trivial proofs.

v1.0.0 – Initial release
Features 🧪
Categories, their properties, and implications between properties can be explored. There is deduction system that automatically deduces properties from more basic ones. Categories can be compared with each other, and one can search for categories with given properties and non-properties.
