Another year has come around quickly and so another chance to have some fun solving the Advent Of Code puzzles for 2023. Once again, I will be attempting to solve these puzzles using Jactl. The version I am using is the latest version (1.3.1 as of time of writing).

Jactl 1.3.0 introduces the ability to checkpoint the current execution state of a script and have it restored and resumed elsewhere after a failure. In order to test this new feature, I implemented a proof-of-concept project that simulates a payment processing system that accepts payment requests, performs some operations by interacting with multiple external systems and then returns a response.

Jactl 1.3.0 fixes a few minor bugs and adds some language features. The main new feature is to support the ability to checkpoint script instance execution state and have it restored and resumed on another instance after a failure.
