We are releasing the first patch release of the 1.5 series.
In this patch release we included 13 PRs since the 1.5.0 release by 7 contributors. We thank all the effort put into improving the language! ❤️
A regression introduced in 1.5.0 prevented the typechecker to correctly infer the type of a union of a splat of types (something of the form
Union(*T)). This is now fixed.
To illustrate, the following code typechecks in 1.4.1 but not in 1.5.0.
class Foo(*T) @value : Union(*T) def initialize(@value) end end p Foo(Int32, String).new(3), Foo(Int32, String).new("")

To maintain and increase the development pace, donations and sponsorships are essential. OpenCollective is available for that.
