  • Messages: Make pgettext search plurals when translation is not found by @tomasr8 in :gh:`1085`

Infrastructure

Documentation

  • Add a mention to the docs that format_skeleton(..., fuzzy=True) may raise by @tomasr8 in :gh:`1106`
  • Two hyperlinks (to CLDR) and some typos by @buhtz in :gh:`1115`

Version 2.15.0

Python version support

  • Babel 2.15.0 will require Python 3.8 or newer. (:gh:`1048`)

Features

  • CLDR: Upgrade to CLDR 44 (:gh:`1071`) (@akx)
  • Dates: Support for the "fall back to short format" logic for time delta formatting (:gh:`1075`) (@akx)
  • Message: More versatile .po IO functions (:gh:`1068`) (@akx)
  • Numbers: Improved support for alternate spaces when parsing numbers (:gh:`1007`) (@ronnix's first contribution)

Infrastructure

  • Upgrade GitHub Actions (:gh:`1054`) (@cclauss's first contribution)
  • The Unicode license is now included in locale-data and in the documentation (:gh:`1074`) (@akx)

Version 2.14.0

Upcoming deprecation

  • This version, Babel 2.14, is the last version of Babel to support Python 3.7. Babel 2.15 will require Python 3.8 or newer.
  • We had previously announced Babel 2.13 to have been the last version to support Python 3.7, but being able to use CLDR 43 with Python 3.7 was deemed important enough to keep supporting the EOL Python version for one more release.

Possibly backwards incompatible changes

  • Locale.number_symbols will now have first-level keys for each numbering system. Since the implicit default numbering system still is "latn", what had previously been e.g. Locale.number_symbols['decimal'] is now Locale.number_symbols['latn']['decimal'].
  • Babel no longer directly depends on either distutils or setuptools; if you had been using the Babel setuptools command extensions, you would need to explicitly depend on setuptools – though given you're running setup.py you probably already do.

Features

  • CLDR/Numbers: Add support of local numbering systems for number symbols by @kajte in :gh:`1036`
  • CLDR: Upgrade to CLDR 43 by @rix0rrr in :gh:`1043`
  • Frontend: Allow last_translator to be passed as an option to extract_message by @AivGitHub in :gh:`1044`
  • Frontend: Decouple pybabel CLI frontend from distutils/setuptools by @akx in :gh:`1041`
  • Numbers: Improve parsing of malformed decimals by @Olunusib and @akx in :gh:`1042`

Infrastructure

  • Enforce trailing commas (enable Ruff COM rule and autofix) by @akx in :gh:`1045`
  • CI: use GitHub output formats by @akx in :gh:`1046`

Version 2.13.1

This is a patch release to fix a few bugs.

Fixes

Version 2.13.0

    • This also enables extraction from static f-strings. F-strings with expressions are silently ignored (but won't raise an error as they used to).

Infrastructure

  • Tests: Use regular asserts and pytest.raises() :gh:`875` – Aarni Koskela
  • Wheels are now built in GitHub Actions :gh:`888` – Aarni Koskela

Version 2.10.3

This is a bugfix release for Babel 2.10.2, which was mistakenly packaged with outdated locale data.

Thanks to Michał Górny for pointing this out and Jun Omae for verifying.

This and future Babel PyPI packages will be built by a more automated process, which should make problems like this less likely to occur.

  • The wheel file is no longer marked as universal, since Babel only supports Python 3.

Version 2.10.0

Upcoming deprecation

  • The get_next_timezone_transition() function is marked deprecated in this version and will be removed likely as soon as Babel 2.11. No replacement for this function is planned; based on discussion in :gh:`716`, it's likely the function is not used in any real code. (:gh:`852`) - Aarni Koskela, Paul Ganssle

Improvements

Version 0.9.4

(released on August 25th 2008)

  • Currency symbol definitions that is defined with choice patterns in the CLDR data are no longer imported, so the symbol code will be used instead.

  • Locale modifiers such as "@euro" are now stripped from locale identifiers when parsing (:trac:`136`).
  • The system locales "C" and "POSIX" are now treated as aliases for "en_US_POSIX", for which the CLDR provides the appropriate data. Thanks to Manlio Perillo for the suggestion.
  • Fixed JavaScript extraction for regular expression literals (:trac:`138`) and concatenated strings.
  • The Translation class in babel.support can now manage catalogs with different message domains, and exposes the family of d*gettext functions (:trac:`137`).

Version 0.9.2

(released on February 4th 2008)

  • Fixed catalogs' charset values not being recognized (:trac:`66`).
  • Numerous improvements to the default plural forms.
  • Fixed fuzzy matching when updating message catalogs (:trac:`82`).

Version 0.9.1

(released on September 7th 2007)

(released on August 20th 2007)

  • The new_catalog distutils command has been renamed to init_catalog for consistency with the command-line frontend.
  • Added compilation of message catalogs to MO files (:trac:`21`).

  • The number formatting functions now also work with numbers represented by Python Decimal objects (:trac:`53`).
  • Added extensible infrastructure for validating translation catalogs.
  • Fixed the extractor not filtering out messages that didn't validate against the keyword's specification (:trac:`39`).
  • Fixed the extractor raising an exception when encountering an empty string msgid. It now emits a warning to stderr.

  • Improved support for detecting Python string formatting fields in message strings (:trac:`57`).
  • CLDR upgraded to the 1.5 release.
  • Improved timezone formatting.
  • Implemented scientific number formatting.
  • Added mechanism to lookup locales by alias, for cases where browsers insist on including only the language code in the Accept-Language header, and sometimes even the incorrect language code.

Version 0.8.1

(released on July 2nd 2007)

  • default_locale() would fail when the value of the LANGUAGE environment variable contained multiple language codes separated by colon, as is explicitly allowed by the GNU gettext tools. As the default_locale() function is called at the module level in some modules, this bug would completely break importing these modules on systems where LANGUAGE is set that way.
  • The character set specified in PO template files is now respected when creating new catalog files based on that template. This allows the use of characters outside the ASCII range in POT files (:trac:`17`).
  • The default ordering of messages in generated POT files, which is based on the order those messages are found when walking the source tree, is no longer subject to differences between platforms; directory and file names are now always sorted alphabetically.
  • The Python message extractor now respects the special encoding comment to be able to handle files containing non-ASCII characters (:trac:`23`).
  • Added N_ (gettext noop) to the extractor's default keywords.
  • Made locale string parsing more robust, and also take the script part into account (:trac:`27`).
  • Added a function to list all locales for which locale data is available.
  • Added a command-line option to the pybabel command which prints out all available locales (:trac:`24`).
  • The name of the command-line script has been changed from just babel to pybabel to avoid a conflict with the OpenBabel project (:trac:`34`).

Version 0.8

(released on June 20th 2007)

  • First public release
