There are some breaking changes, both in GAX v4 and in the generated code. The changes that aren't specific to any given API are described in the Google Cloud documentation. We don't anticipate any changes to most customer code, but please file a GitHub issue if you run into problems.

New features

  • Provide metadata for the object that has been downloaded. Fixes issue 7897 (commit e60a0d4)

No API surface changes; just updated dependencies. In particular, this uses Google.Apis version 1.45.0, which uses a more memory-efficient approach to uploads.

Version 3.0.0-beta02, released 2020-03-19

  • Commit cdc1f03:
    • Fixes and new features for URL signing:
      • V4 is now the default signing mechanism.
      • V4: collapses tabs in header's values.
      • V4: uses payload hash if provided. V2 ignores payload hash if provided (as it does with almost every other header).
      • V4: supports signing of custom query parameters. V2 will throw if custom query parameters are set.
      • V2 and V4: supports setting URL scheme (http or htpps only).
      • V2 and V4: supports Virtual-hosted style URLs.
      • V4: supports bucket bound domain URLs. V2 will throw if bucket bound domain is set.
  • Commit 71ca7e8: Removes obsolete methods.

There are breaking changes around UrlSigner; code that still compiles should be fine - otherwise, use the UrlSigner.RequestTemplate and UrlSigner.Options classes to specify options that were previously in method parameters.

Version 3.0.0-beta01, released 2020-02-20

Upgrade dependencies to GAX v3. Currently there are no direct surface changes, but breaking changes in GAX may affect users, for example in terms of async pagination.

More direct breaking changes are expected in this package before 3.0.0 is released, specifically around signed URLs.

  • New interface UrlSigner.IBlobSigner for more flexibility when creating signed URLs
