StreamEx v0.3.4 Release Notes

    • 🛠 Fixed: EntryStream.of(List<T>), EntryStream.of(T[]) and StreamEx.runLengths returned stream of Map.Entry objects which violate the documented contract for equals and hashCode.
    • 🛠 Fixed: pairMap method for all streams worked incorrectly when previous steps included parallel().flatMap() due to JDK bug. New version may also work faster in parallel for certain sources.
    • 🛠 Fixed: collapse-based methods (collapse, groupRuns, runLengths, intervalMap) worked incorrectly in various cases in parallel mode. New version may also work faster in parallel for certain sources.
    • Fixed: minBy*/maxBy* for primitive streams now return strictly the first matched element (not the arbitrary one).
    • ⚡️ Optimized: minBy/maxBy methods for primitive streams now call keyExtractor function at most once per element
    • ⚡️ Optimized: many stream creation methods (zip for all streams, EntryStream.of(List), StreamEx.ofSubLists, etc.) now use custom spliterator.
    • ⚡️ Optimized: IntStreamEx.ofChars reimplemented for JDK 8 as original CharSequence.chars implementation is poor.
    • ➕ Added construction of all stream types from the Spliterator.
    • 📚 Updated documentation
