[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

[#127] Add utils: freeze-to-string, thaw-from-string (@piotr-yuxuan)
[#113 #114] Add support for object arrays (@isaksky)
[#83 #112] Add support for deftype (@isaksky)
[#83 #113] Add support for URIs (@isaksky)
[#126] extend-freeze: include id collision odds in docstring

Fixes

[#120] Update freezable? to cover nil
