Elixir v1.19.4 released

1. Enhancements

Mix

• [mix xref] Add --min-cycle-label to help projects adapt to the more precise mix xref graph reports in Elixir v1.19. In previous versions, Elixir would break a large compilation cycle into several smaller ones, and therefore developers would check for --min-cycle-size on CI. However, the issue is not the size of the cycle (it has no implication in the amount of compiled files), but how many compile-time dependencies (aka compile labels) in a cycle. The new option allows developers to filter on the label parameter

2. Bug fixes

Elixir

• [File] Ensure File.cp_r/3 reports non-existing destination properly (instead of source)

ExUnit

• [ExUnit] Fix formatter crash when diffing takes too long
• [ExUnit] Ensure parallel matches in assert propagate type information

Logger

• [Logger] Fix regression where formatter would crash when given chardata (the crash would happen when logging non-ASCII characters)

Mix

• [mix help] Ensure app:APP works when the project or its dependencies were not yet compiled
• [mix escript.build] Ensure the hex application can be included in escripts
