v2.12.1 / 2016 Jul 26

[com.taoensso/nippy "2.12.1"]

• Hotfix: thaw was missing support for deprecated serializable, record types [@rwilson]

v2.12.0 / 2016 Jul 24

[com.taoensso/nippy "2.12.0"]

This is a major release that may involve some breaking API changes in rare cases for users of some low-level or obscure features that have been made private or removed. If your code compiles with this new version of Nippy, you should be fine.

As with all Nippy releases: this version can read data written by older versions but older versions may not be able to read data written by this version.

No changes since 2.12.0-RC2.
Changes since 2.11.1:

• BREAKING: dropped support for *final-freeze-fallback* (rarely used)
• BREAKING: dropped support for *default-freeze-compressor-selector* (rarely used)
• BREAKING: made several implementation details private, incl. most low-level write-<x> and read-<x> fns (rarely used)
• Performance: several significant speed + space efficiency improvements, including more variable-sized types
• New built-in types (these previously fell back to the reader): regex patterns, symbols
• New experimental caching feature (please see cache docstring for details)
• New: fast-freeze, fast-thaw utils (please see docstrings for details)
• Change: freeze return val is no longer auto type hinted as ^bytes (had a performance cost, rarely used)
• Hotfix: fn?s were incorrectly reporting true for serializable?
• Hotfix: final-freeze-fallback back compatibility was broken

v2.11.1 / 2016 Feb 25

Hotfix for broken Clojure 1.5 support

[com.taoensso/nippy "2.11.0-RC1"]

v2.11.0-beta1 / 2015 Dec 13

This is a major performance release that drops default support for thawing Nippy v1 archives but is otherwise non-breaking

• BREAKING: thaw now has :v1-compatibility? opt set to false by default (was true before) [1]
• Performance: optimize serialized size of small maps, sets, vectors, bytes
• Performance: optimized (no copy) freeze when using no compression or encryption
• Implementation: swap most macros for fns (make low-level utils easier to use)

[com.taoensso/nippy "2.11.0-beta1"]

Notes

[1] Use (thaw <frozen-byte-array> {:v1-compatibility? true}) to support thawing of data frozen with Nippy v1 (before ~June 2013)

v2.10.0 / 2015 Sep 30

This is a major feature/performance release that drops support for Clojure 1.4 but is otherwise non-breaking

• BREAKING: drop support for Clojure 1.4 (Nippy now requires Clojure 1.5+)
• Performance: various small performance improvements
• New: dynamic *default-freeze-compressor-selector*, set-default-freeze-compressor-selector! util
• New: dynamic *custom-readers*, swap-custom-readers! util
• New: edn writes now override dynamic *print-level*, *print-length* for safety

v2.9.1 / 2015 Sep 14

This is a hotfix release with an important fix for Nippy encryption users

• Fix: broken encryption thread-safety [#68]

[com.taoensso/nippy "2.9.1"]

v2.9.0 / 2015 June 1

This is a major, non-breaking release that improves performance and makes thawing more resilient to certain failures. Identical to v2.9.0-RC3.

• Robustness: improve error handling for unthawable records
• Performance: switch doseq -> (faster) run! calls
• Performance: eliminate some unnecessary boxed math
• New: allow intelligent auto-selection of freeze compression scheme using :auto compressor (now the default). This can result in significant speed+space improvements for users serializing many small values.

v2.8.0 / 2015 Feb 18

This is a maintenance release with some minor fixes and some dependency updates.

• CHANGE: Throw a clear error message on insufficient Encore dependency.
• FIX [#59]: freezable? should return true for clojure.lang.PersistentVector (@chairmanwow).
• FIX [#63]: Missing thaw exception cause (@cespare).
