Version 1.13 of API Simulator features bug fixes and upgraded dependencies to fix vulnerabilities:
- Upgraded a good number of dependencies, fixing vulnerabilities along the way.
- Fix: Extended charset characters in a callback request may cause incorrect output.
- Smaller fixes and optimizations.
- There is a breaking change if you are using H2 database with the JDBC driver bundled with API Simulator – it was upgraded from v1.x.y to v2.2.224 to address security vulnerabilities, which isn’t backward compatible. See here for how to migrate to H2 v2.
We invite you to learn more about API Simulator, download and install it, and run the examples included in the download. Why not even create API simulations to help your own testing and development?
