Changes

Below we list the most remarkable changes in the language, compiler and stdlib. For more details, visit the full changelog.

This change brings a couple of bugfixes for regressions introduced in 1.16.0.

The most important fix is for a performance regression in the compiler which for some programs would blow up compile time (#15708). This was particularly observed with -Dexecution_context, but it’s not dependent on that.

Other bug fixes are specific to execution contexts:

  • Fiber::ExecutionContext::Isolated#wait now suspends the fiber (#15720).
  • CRYSTAL_LOAD_DEBUG_INFO=1 now works with -Dexecution_context (#15704, #15724).

Other changes:

  • Int#humanize_bytes shows the unit_separator even if the prefix is empty (#15683).
  • Remove double listing ReferenceStorage as a sub type of Value (#15706).
