historique
Historique du projet et usages
GNU Libidn2 is the GNU successor to Libidn for IDNA2008 and Unicode TR46 internationalized-domain-name processing.
Historique du projet
The IETF IDNA2008 RFC series replaced the earlier IDNA2003 model, describing a revised protocol and definitions for internationalized domain names. Libidn2 was created to implement that newer standards family while retaining package-level continuity for GNU users.
The Libidn2 NEWS file records an initial 0.0 alpha release on 2011-03-09 for public API review, with IDNA2008 lookup mostly implemented. Release 0.2 on 2011-03-30 added the idn2 command-line tool and made lookup/register functions operational.
Release 0.12 on 2016-12-26 added TR46/UTS #46 support to the API and idn2 utility. Release 2.0.0 on 2017-03-29 changed the version numbering scheme and added to-ASCII and to-Unicode conversion functions corresponding to Libidn functions. Release 2.0.5 on 2018-05-18 switched the default library behavior to IDNA2008 as amended by non-transitional TR46.
Historique d'adoption
The GNU Libidn page explicitly calls Libidn2 the successor of GNU Libidn and notes that it provides IDNA2008, TR46, and a compatibility layer for GNU Libidn. That made it the practical migration path for distributions and network applications moving away from IDNA2003 behavior.
Libidn2 is package-visible because applications often need a shared, audited implementation of Unicode domain-name conversion rather than hand-rolling security-sensitive Punycode and normalization behavior.
Modes d'utilisation
Users call idn2 for command-line conversion and debugging, while applications link the library for IDNA lookup and registration conversions. The manual emphasizes correct locale and UTF-8 handling because feeding bytes in the wrong character set can produce errors or wrong output.
Pourquoi les passionnés de paquets s'y intéressent
Libidn2 is where DNS, Unicode versioning, security-sensitive string handling, and compatibility policy meet. Packagers care about it because changing from libidn to libidn2 can alter IDNA behavior, but staying on IDNA2003 can be wrong for software that expects IDNA2008/TR46.
It is also a good example of a successor package that is not just a new ABI: it represents a standards transition and a different view of what domain names should accept.
Chronologie
- 2010: RFC 5890 and related RFCs documented the IDNA2008 revision that superseded IDNA2003.
- 2011: Libidn2 0.0 alpha released for public API review.
- 2011: Libidn2 0.2 added the idn2 command-line tool.
- 2016: Libidn2 0.12 added TR46/UTS #46 support.
- 2017: Libidn2 2.0.0 changed version numbering and added Libidn-corresponding conversion APIs.
- 2018: Libidn2 2.0.5 made IDNA2008 plus non-transitional TR46 the default behavior.
Related projects
- GNU Libidn is the predecessor and compatibility target.
- GNU libunistring is related through Unicode string support used by Libidn2 builds.
- RFC 5890, RFC 5891, and Unicode UTS #46 define the standards context around Libidn2.
