This release of PyOxidizer is significant rewrite of the previous version.
The impetus for the rewrite is to transition from TOML to Starlark
configuration files. The new configuration file format should allow
vastly greater flexibility for building applications and will unlock a
world of new possibilities.
The transition to Starlark configuration files represented a shift from
static configuration to something more dynamic. This required refactoring
a ton of code.
As part of refactoring code, we took the opportunity to shore up lots
of the code base. PyOxidizer was the project author's first real Rust
project and a lot of bad practices (such as use of .unwrap()/panics)
were prevalent. The code mostly now has proper error handling. Another
new addition to the code is unit tests. While coverage still isn't
great, we now have tests performing meaningful packaging activities.
So regressions should hopefully be less common going forward.
Because of the scale of the rewritten code in this release, it is expected
that there are tons of bugs of regressions. This will likely be a transitional
release with a more robust release to follow.
