This project uses Break Versioning.

v3.5.0-RC1 (2024-10-28)

This is a non-breaking maintenance release that updates dependencies and includes read support for more native array types to be introduced in a future v3.6 release.

It should be safe to update from (at least) all recent versions of Nippy.

Updating from NippyChanges to API?Changes to byte output?Recommended update sequence [1]
v3.4.2 (2024-05-26)---
v3.4.1 (2024-05-02)---
v3.4.0 (2024-04-30)-Yes-
v3.3.0 (2023-10-11)---
v3.2.0 (2022-07-18)---
v3.1.3 (2022-06-23)---

[1] Relevant only when introducing support for new types, to help with rolling updates

If updating from older versions of Nippy, please see the relevant release notes.

As always:

  • See operational considerations for info on: data compatibility, rolling updates, rollback support, etc.
  • It's always a good idea to ensure adequate testing in your environment before updating against production data!
  • Please report any unexpected problems 🙏

v3.4.2 (2024-05-26)

Dep: Nippy is on Clojars.
Versioning: Nippy uses Break Versioning.

⚠️ This release addresses a security vulnerability in Nippy's upstream compression library and is recommended for all existing users.

It should be a straight-forward and non-breaking update for almost everyone:

v3.4.1 (2024-05-02)

Dep: Nippy is on Clojars.
Versioning: Nippy uses Break Versioning.

Like v3.4.0 but introduces an internal mechanism to help make it easier for some users that do rolling updates from earlier versions of Nippy.

Still, the usual warning applies: data frozen by Nippy version X should ideally be thawed by version >= X, otherwise you run the risk of the thaw throwing when unfamiliar types are encountered. Please note that this can affect rolling updates, and can limit your ability to revert a Nippy update. Please ensure adequate testing in your environment before updating against production data!

- Peter Taoussanis

Changes since v3.4.0

  • [mod] Due to some internal format changes, Nippy v3.4.1 may produce different serialized output to v3.4.0 and earlier versions of Nippy. Most users won't care about this, but you could be affected if you depend on specific serialized byte values (for example by comparing serialized output between different versions of Nippy).

v3.4.0 (2024-04-30)

Dep: Nippy is on Clojars.
Versioning: Nippy uses Break Versioning.

This is a non-breaking feature and maintenance release and should be a safe update for existing users. But as always, please test carefully and report any unexpected problems, thank you! 🙏

IMPORTANT: data frozen by Nippy version X should always be thawed by version >= X, otherwise you run the risk of the thaw throwing when encountering unfamiliar types. Please note that this can affect rolling updates, and can limit your ability to revert a Nippy update. Please ensure adequate testing in your environment before updating against production data.

[com.taoensso/nippy "3.1.1"]

This is a non-breaking, bugfix release. But please note that large keywords or symbols (with >127 characters) frozen with >=v3.1.1 will need >=v3.1.1 to thaw.

Changes since v3.0.0

  • Add several standard java.time classes to default *thaw-serializable-whitelist*.

v3.1.0-RC1 (2020-10-24)

[com.taoensso/nippy "3.1.0-RC1"]

This is a non-breaking, minor feature release.

New since v3.0.0

  • [#135 #128] Added native freeze/thaw support for java.time.Instant on JVM 8+ (@cnuernber).

v3.0.0 (2020-09-20)

[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
