Release 6.0.0-pre.20220123.2 (2022-01-28)

Baseline: e2abe2b519fe86b213d822c1fadd7a51d6d3a3f6

Incompatible changes:

  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`
  - Error Prone now checks for unused return values of additional
    methods on `java.lang.Object`, which can be disabled using
    `--javacopts=-Xep:ReturnValueIgnored:OFF`

Important changes:

  - provider() has a new parameter: init, a callback for performing
    pre-processing and validation of field values. Iff this parameter
    is set,
    provider() returns a tuple of 2 elements: the usual provider
    symbol (which,
    when called, invokes init) and a raw constructor (which bypasses
    init).

This release contains contributions from many people at Google, as well as Chad Miller, Christopher Sauer, dmaclach, floriographygoth, jheaff1, juanchoviedo, Keith Smiley, Oscar Bonilla, Paul Tarjan, Ulrik Falklof, Zhongpeng Lin.
