Change Log

All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.

3.0.3

  • Build system improvements

3.0.2

  • Typo fixes in docs
  • Support for GNUInstallDirs in CMake

3.0.1

  • CMake corrections

3.0.0

  • Core algorithm reworked and simplified, which brings many small improvements
    • Numbers of arbitrary lengths are now compared correctly
    • Versions are now split more uniformly, so now 1.0alpha1 == 1.0.alpha1 == 1.0alpha.1 == 1.0.alpha.1
    • Any number of alphabetic/numeric compoments are now allowed (1a2b3c4 is no longer effectively trimmed to 1a2)
  • Implement VERSIONFLAG_LOWER_BOUND and VERSIONFLAG_UPPER_BOUND flags
  • Added version_sort and version_explain (not installed) utilities, useful for debugging
  • Removed deprecated version_signature API

2.9.1

  • Add support for errata keyword as post-release.

2.9.0

  • Modernized CMake code, added support for CMake export mechanism, so it's now super easy to use libversion from CMake
  • Added export header so shared library can now be used on Windows
  • Better handling of deprecated APIs
  • Fixed library name conflicts on Windows

2.8.2

  • Fixed undefined behavior in string comparison

2.8.1

  • Fixed installation for out-of-source builds
  • Documentation updates

2.8.0

  • Deprecated version_compare3() as well, as it would create ambiguities for higher level language wrappers
  • Exposed libversion version to consumer code via LIBVERSION_VERSION_ATLEAST macro

2.7.0

  • API cleanup: all version_compare* methods are now replaced with version_compare2(), version_compare3(), and version_compare4() which are consistent and suggest the number of arguments. version_compare_simple(), version_compare_flags(), and version_compare_flags2() are thus deprecated and will be removed in further releases.
  • Also deprecate version_signature_simple() which had no practical use.

2.6.0

  • Implemented version_compare_flags2() 4-argument function which allows to specify flags for either compared version independently, without the need to squish them into the single argument
  • Added shared library

2.5.0

  • Implemented VERSIONFLAG_ANY_IS_PATCH flag which makes any alphabetic characters encountered in versions treated as post-release.

2.4.0

  • Allow to specify P_IS_PATCH flag to each comparison argument separately

2.3.0

  • Handle pl ("patchlevel") keyword as post-release.

2.2.0

  • Handle any keyword which starts with post equally (as post-release). This is now also consistent with how keywords starting with pre are handled.

2.1.0

  • Added special handling of post keyword (as post-release, similar to patch)

2.0.0

  • Add version_signature_single() function to generate format signature for a version string
  • Header file renamed to libversion/version.h

1.3.0

  • Add version_compare_flags(), equivalent of version_compare_simple() which takes additional flags argument used to fine tune its behavior.
  • Implemented VERSIONFLAG_P_IS_PATCH flag which affects the handling of p letter encountered in versions.

1.2.0

  • Enable position independent code so libversion can be used with shared libraries

1.1.0

  • Improved handling of keywords, including fixed handling of patch
  • Improved documentation

1.0.0

  • Initial release featuring single function version_compare_simple(v1, v2)
