Release Notes

square/okio (com.squareup.okio:okio)

v3.9.0

2024-03-12

• New: FileSystem.SYSTEM can be used in source sets that target both Kotlin/Native and
  Kotlin/JVM. Previously, we had this symbol in each source set but it wasn't available to
  common source sets.
• New: COpaquePointer.readByteString(...) creates a ByteString from a memory address.
• New: Support InflaterSource, DeflaterSink, GzipSink, and GzipSource in Kotlin/Native.
• New: Support openZip() on Kotlin/Native. One known bug in this implementation is that
  FileMetadata.lastModifiedAtMillis() is interpreted as UTC and not the host machine's time zone.
• New: Prefer NTFS timestamps in ZIP file systems' metadata. This avoids the time zone problems
  of ZIP's built-in DOS timestamps, and the 2038 time bombs of ZIP's extended timestamps.
• Fix: Don't leak file handles to opened JAR files open in FileSystem.RESOURCES.
• Fix: Don't throw a NullPointerException if Closeable.use { ... } returns null.
