## 3.1.0

This is a minor feature release.

* Add a function for atomic file writes

## 3.0.0

Maintenance:
* Update dependencies to take up clj-parent 4

## 2.5.2

This is a minor maintenance release.

Maintenance:

## 2.5.0

This is a minor feature release.

Features:

## 2.4.0

This is a minor feature and improvement release.

Features:
* add a `utf8-string->sha256` function, directly analogous to `utf8-string->sha1`
* add a `file->sha256` function, equivalent to reading a file's contents as a
  UTF-8 string and hashing the result. Uses an InputStream internally to avoid
  reading the entire file into memory at once.

Improvement:

  entire traditional ephemeral port range of 49152 through 65535.

Features:

* Add an `assoc-if-new` macro, which associates a map key to a value only if
  the key does not already exist in the map.
* Add a `deref-swap!` function, which behaves like deref but returns the old
  value instead of the new one.

  character sets.

Maintenance:

  collisions.

* Add a `normalized-path` fn to replace the one that was removed from raynes.fs

## 1.2.0

  nodes of a map
* Add new `zipper?` predicate which can be used to assert that an object
  is a clojure zipper.
* Add new `while-let` macro
* Add new `rand-weighted-selection` function
* Add new `to-sentence` variant of string join

## 1.0.0
* Promoting previous release to 1.0.0 so that we can be more deliberate about
  adhering to semver from now on.

## 0.5.2
 * Minor change to the cli! function so that, in addition to the data that it already returned, it now also returns a string representation of a banner/usage summary.  Callers can use this to display a help message if additional validation of the cli args fails.

 * Added some JSON utility functions
 * Added a deep-merge utility function
