[com.taoensso/nippy "3.0.0"]

This release is focused on smoothing out rough edges left by CVE-2020-24164 [#130], and to ease transition from versions of Nippy < v2.15.0 final.

See here for recommended steps when updating any Clojure/Script dependencies.

Note that there's separate details below for upgrading from v2.15 vs v2.14:

Upgrading from v2.15 (usually non-breaking)

Usually a non-breaking drop-in replacement, but there's some changes you might like to take advantage of. See [#130] for detailed upgrade instructions.

Changes

  • [BREAKING] Bumped minimum Clojure version from v1.5 to v1.7.
  • [BREAKING] :nippy/unthawable responses now have a standardized form: {:nippy/unthawable {:type _ :cause _ ...}. Most folks won't care about this change unless they have code specifically to deal with :nippy/unthawable responses.
  • [Deprecated] *serializable-whitelist* has been split into two separate vars: *freeze-serializable-allowlist*, *thaw-serializable-allowlist*. See [#130] for details.
  • By default, freeze now allows the use of Java's Serializable for any class. thaw continues to be restrictive by default, and will quarantine any objects not on the class allowlist. See [#130] for details.

New

  • [#122] Option to disable freezing and/or thawing of metadata.
  • freeze and thaw now support opts: :serializable-allowlist, :incl-metadata?.
  • New read-quarantined-serializable-object-unsafe! util to read quarantined Serializable objects. See API docs and/or [#130] for details.
  • Add allow-and-record-any-serializable-class-unsafe util. See API docs and/or [#130] for details.

Upgrading from v2.14 (may be BREAKING)

Likely breaking. Please see [#130] for detailed upgrade instructions.

Changes

  • [BREAKING] Bumped minimum Clojure version from v1.5 to v1.7.
  • [BREAKING] [#130] thaw will now quarantine Serializable objects whose class is not allowed by *thaw-serializable-allowlist*. See [#130] for details.
  • [BREAKING] :nippy/unthawable responses now have a standardized form: {:nippy/unthawable {:type _ :cause _ ...}. Most folks won't care about this change unless you have code specifically to deal with :nippy/unthawable responses.
  • [#101] Switch default encryptor from AES-CBC to AES-GCM (faster, includes integrity check)

New

Fixes

  • [#120] Update freezable? to cover nil
