Release Notes

lysine-dev/okio (com.squareup.okio:okio-fakefilesystem)

v3.18.2

2026-09-04

• Fix: Don't change behavior of base64-encoding. We introduced a bug in Okio 3.18.1 that caused
  base64 strings to be encoded without padding, even though the previous and expected behavior is
  to encode such strings with padding (= characters). The bug impacts callers who compiled
  against Okio releases < 3.18.0, and executed on Okio releases >= 3.18.
