cuid v2.0.1

cuid v2.0.1

Note that starting with this release, releases on GH will only be made
for the main cuid crate. Tags will still be created for both cuid
and the cuid1 and cuid2 subcrates, though.

cuid2 v0.1.6

Changed

• 15-20% performance improvement for cuid2 generation, due mostly to
  optimizations in create_entropy(), along with a few other smaller
  optimizations

cuid v2.0.0

This release contains breaking changes, specifically the removal of functions
that were previously marked as deprecated. Please see the notes below for details.

Removed

• The top-level cuid(), slug(), and is_cuid() functions have been
  removed. These were implicitly yielding v1 CUIDs, and it is now required
  for CUID version to be explicitly specified.

  Importing cuid::v1::* or qualifying each function like v1::cuid() is
  equivalent to the removed top-level functions.

  In addition, version-specific top-level function names like cuid1(),
  cuid1_slug(), and is_cuid1() are provided.

This release also pulls in the following releases of the cuid1 and cuid2
subpackages:

• https://github.com/mplanchard/cuid-rust/releases/tag/cuid1-v0.1.1
• https://github.com/mplanchard/cuid-rust/releases/tag/cuid2-v0.1.5

These are both patch releases, with no interface-level changes.

cuid2 v0.1.5

Changed

• Updated a variety of dependencies, Rust edition, and so on.
• Updated transitive dependency specification for getrandom to
  current version, resolves #19

cuid1 v0.1.1

Changed

• Updated a variety of dependencies, Rust edition, and so on.
• Updated transitive dependency specification for getrandom to
  current version, resolves #19

cuid2 v0.1.4

cuid2 v0.1.4

Fixed

• Replaced std::sys::SystemTime with web_time::SystemTime so that
  CUID generation does not panic in WASM builds.

cuid1 v0.1.0

cuid1 v0.1.0

Technically, this is a new crate! This was published containing the
fix below. This will be included in the next major version of cuid,
which will be a breaking release in which the top-level cuid() function
is replaced by explicit calls to either cuid1() or cuid2().

Fixed

• (v1) Replaced std::sys::SystemTime with web_time::SystemTime so
  that CUID generation does not panic in WASM builds

cuid v1.3.3, cuid2 v0.1.3

cuid2 v0.1.3, cuid 1.3.3

Upcoming

• The next major release will be a breaking release, dropping the
  top-level cuid(), slug(), and is_cuid() functions in favor of
  their version-specific counterparts (see below).
• I also intend to split the v1 CUID functionality out into its own
  crate and publish it independently, like I have done for cuid2.
  The top-level cuid crate will then pull in the sub-crates depending
  on features, making it easy to just pull the CUID version you need.

Added

• Provide new top-level functions from the cuid library to disambiguate
  CUID versions:
  • cuid::cuid1(): generate a v1 CUID, replacement for deprecated cuid()
  • cuid::cuid1_slug(): generate a v1 CUID slug, replacement for deprecated slug()
  • cuid::is_cuid1() - check whether a string looks like it could be a v1 CUID,
    replacement for deprecated is_cuid()
  • cuid::is_cuid1_slug() - check whether a string looks like it could be a v1 CUID
    slug, replacement for deprecated is_cuid()
  • cuid::cuid2_slug() - generate a v2 CUID of length 10
  • cuid::is_cuid2_slug() - check whether a string looks like could be a v2 CUID
    slug
  • cuid::Cuid2Constructor - expose the v2 CUID constructor interface
• Added a couple of functions to cuid2 for parity with v1 functions:
  • cuid2::slug() - generate a v2 CUID of length 10
  • cuid2::is_slug() - check whether a string looks like could be a v2 CUID
    slug
• Added support for webassembly builds. Builds are tested for wasm32-unknown-unknown
  and wasm32-wasi targets. I intend to add Javascript bindings and publish
  npm packages in an upcoming update.
  • The system hostname is not available to WASM, so for the CUID v1
    fingerprint algorithm, we instead use a v4 UUID. This does mean the
    fingerprint will not be consistent on a host over time, which slightly
    diverges from the behavior of CUIDs on other targets. Please open an
    issue if this is a problem for you.

Changed

• CUID v1 functions are no longer marked as deprecated. The original JS
  library was marked as insecure and deprecated by its creators, but this
  was merely due to their personal stance that any k-sortable IDs are
  insecure and should not be used. This library's author does not share
  the same view. New functions have been provided to better disambiguate
  creating v1 vs v2 IDs, and functions that do not explicitly specify
  a version are still marked as deprecated.
• The CUID binaries now randomize the counter prior to generating an ID,
  rather than always starting at 0. This ensures that commandline-generated
  CUIDs do not lose entropy relative to library-generated CUIDs due to
  always having the same counter value.
• The cuid2::is_cuid()/cuid::is_cuid2() function has been improved and
  now rejects more strings that are invalid CUIDs (contribution by @stormshield-kg)
• The cuid2 binary now supports an optional --length|-l argument, which
  enables specifying the length of the generated CUID (contribution by @der-fruhling)

Removed

• Removed old benchmarks and #[cfg(nightly)] blocks. Criterion benchmarks
  are the important ones, and those remain.

cuid2 v0.1.2

cuid2 v0.1.2

Changed

• Internal updates to match updated CUID construction logic in the reference
  implementation,
  specifically:
  • Simplified hashing function, no longer adding additional entropy in addition
    to building a hash
  • Increased range of possible values for counter initialization
  • Random numbers for entropy are now random numbers from [0, 36), rather than
    a random choice from a static array of prime numbers
