## [1.4.0](https://togithub.com/google/uuid/compare/v1.3.1...v1.4.0) (2023-10-26)

### Features

* UUIDs slice type with Strings() convenience method ([#133](https://togithub.com/google/uuid/issues/133)) ([cd5fbbd](https://togithub.com/google/uuid/commit/cd5fbbdd02f3e3467ac18940e07e062be1f864b4))

### Fixes

* Clarify that Parse's job is to parse but not necessarily validate strings. (Documents current behavior)

Reduce custom error allocation (#70)

Zero allocation by using non-pointer error.

related #69

name old time/op new time/op delta
ParseBadLength-16 15.4ns ± 0% 3.5ns ± 0% ~ (p=1.000 n=1+1)

Use a custom error type for invalid lengths, replacing `fmt.Errorf` (#69

)

* Add benchmarks for different kinds of invalid UUIDs

Also add a test case for too-short UUIDs to ensure behavior doesn’t
change.

* Use a custom error type for invalid lengths, replacing `fmt.Errorf`

This significantly improves the speed of failed parses due to wrong
lengths. Previously the `fmt.Errorf` call dominated, making this the
most expensive error and more expensive than successfully parsing:

BenchmarkParse-4 29226529 36.1 ns/op
BenchmarkParseBadLength-4 6923106 174 ns/op
BenchmarkParseLen32Truncated-4 26641954 38.1 ns/op
BenchmarkParseLen36Corrupted-4 19405598 59.5 ns/op

When the formatting is not required and done on-demand, the failure per
se is much faster:

BenchmarkParse-4 29641700 36.3 ns/op
BenchmarkParseBadLength-4 58602537 20.0 ns/op
BenchmarkParseLen32Truncated-4 30664791 43.6 ns/op
BenchmarkParseLen36Corrupted-4 18882410 61.9 ns/op
