2.2.14 2014-06-16T13:29:09-0600
Eliminate some clang(1) warnings. 2.2.13 2014-06-11T11:08:11-0600 Eliminate some valid compiler warnings. 2.2.12 2014-06-02T13:28:49-0600 Added "nucleon" (alias "nuc") to database as "mole/(avogadro's number)" to support units like "Mev/nucleon". 2.2.11 2014-04-30T14:40:58-0600 Removed incorrect whitespace from top-level CMakeLists.txt file. 2.2.10 2014-04-18T13:56:11-0600 Added "apt-get update" to APT install example. 2.2.9 2014-04-18T13:05:44-0600 Documented how to install a binary-distribution on a 32-bit Ubuntu system. 2.2.8 2014-04-17T13:30:40-0600 Added reference to math library to build of UDUNITS library. 2.2.7 2014-04-16T09:05:47-0600 Documentation: Added more instances when ut_free() should be called. Added hyperlinks for functions in the synopsis section. 2.2.6 2014-04-08T12:57:50-0600 Fixed parsing of a timestamp "unit" with a "naked hour" (e.g., "days since 2014-04-08 06"). 2.2.5 2014-04-03T12:51:46-0600 Added missing "Makefile.in" to source-distribution. 2.2.4 2014-01-21T10:14:37-0700 Corrected version information in documentation. The Git plugin for Eclipse doesn't yet support Git hooks, so the pre-commit hook wasn't working. 2.2.3 2014-01-16T14:02:38-0700 Added vetting of the autoconf-based build to the continuous-delivery pipeline. 2.2.2 Documentation: Changed URL of Unidata yum(1) repository from <http://www.unidata.ucar.edu/yum-repo/CentOS/6/$basearch> to <http://www.unidata.ucar.edu/repos/yum/CentOS/6/$basearch>. 2.2.1 UDUNITS-1 Interface: Squashed bug in UDUNITS-1 interface that would not indicate an error if an ENOMEM error occurred. Documentation: Corrected name of installation-prefix variable in cmake build example for Windows (UDUNITS_INSTALL_PREFIX -> CMAKE_INSTALL_PREFIX). 2.2.0 New Features: Program udunits2(1): Added "-H have" and "-W want" options. Added support for numeric unit amount so that "0 degC" equals "32 degF". Library udunits2(3): Added ut_get_path_xml() to retrieve pathname of XML unit database. Units Database: Added units "molecule" (for conversion with "mole") and "bit". Misc: Removed bundled EXPAT package. Ported code to 32-bit Windows-7 under MinGW. Added explicit chapters on the unit utility and unit library to the top-level package documentation. Bug Fixes: Library udunits2(3): Corrected logic of checking for location of <noplural> element. Units Database: Corrected ISO Latin-1 encodings that somehow got corrupted. Release Engineering: Added support for building by CMake and for creating binary distributions by CPack. Added scripts and configuration-files to support continuous-delivery. Added acceptance-test scripts for 32-bit Ubuntu 12 (Precise Pangolin) and 32-bit Windows-7. Currently, only the Ubuntu script is used in the continuous-delivery pipeline. Misc: Changed file LICENSE to COPYRIGHT and corrected copyright year in many files. Refactored the documentation to make it more version aware. 2.1.24 2011-09-12 15:01-600 Removed superfluous "the" from library documentation. Added (against my better judgement) symbols "ppm", "ppb", "ppt", "ppq", and (shamefully) symbols "ppmv", "ppbv", "pptv", and "ppqv" to the "common" units database. Improved ut_decode_time(): the returned "seconds" value will now always be less than 60. Thanks Christian. 2.1.23 2011-05-19 13:35:40-600 Corrected "make install". Will now create the installation-directory $(DESTDIR)$(htmldir) for holding the symbolic links for HTML access to the unit database if that directory doesn't exist. Modified "formatter.c" to more rigorously handle the return value of snprintf(). Modified documentation on ut_format() to indicate that the number of bytes returned depends on the snprintf() function that's used. 2.1.22 2011-05-16 10:50:34-600 Corrected ut_compare(3) for Galilean units (e.g., "1.01 m" and "1.1 m"). Corrected access to units database from documentation for both installations and the online webpages. Added shared library version numbers. Modified use of snprinf(3) in "formatter.c" to handle case where snprintf(3) returns the number of characters that *would* have been printed had the buffer been big enough (change in Unix standard from X-Open 2 to X-Open 3). This should prevent segmentation violations from occurring if the print-buffer is too small. Thank you Alex Cobb. 2.1.21 2011-01-24 Eliminate expectation and use of leading scale factor in the "have" unit of udunits2(1). Add verification of commit status to "make ftp". Add dependency of documentation on version. Add "force" flag to tagging rule in makefile. 2.1.20 2010-12-20 Added "fahrenheit" as an alias for "degrees fahrenheit". Added hyperlinks from HTML documentation to XML files of the units database. 2.1.19 2010-08-17 Moved ut_set_error_message_handler(ut_ignore) call in version 2.1.18 to eliminate more messages. 2.1.18 2010-08-13 Made the UDUNIT-1 function utInit() call ut_set_error_message_handler(ut_ignore) to make use of the UDUNITS-1 API more backward compatible. 2.1.17 2010-06-23 Added tagging of version in repository to "make ftp". Moved call to ut_set_second() in XML parser from after the XML file is read to as soon as the "second" unit is encountered. 2.1.16 2010-06-21 Corrected and updated definition of "e" -- the charge of an electron. 2.1.15 2010-05-27 Corrected return value of ut_get_status() when ut_parse() fails due to a syntax error. Added missing "void" parameter to declarations of UDUNITS-1 functions utIsInit() and utTerm(). Added commentary about the hybrid Gregorian/Julian calendar to the library documentation. Added the following units: "potential_vorticity_unit" (1e-6 m2 s-1 K kg-1) "einstein" (mole) Added "u" as a symbol for "micro". 2.1.14 2010-01-29 Modified the build procedure. It now 1) Builds the Expat (XML parsing) library that's bundled with the UDUNITS-2 package if and only if the host system doesn't have one; and 2) Installs the bundled Expat library if that library is built. Documented the need for linking against an Expat library. 2.1.13 2010-01-21 Modified the build procedure slightly. It now 1) Supports cross-compilation; and 2) Installs the info(1) documentation files by default. 2.1.12 2010-01-11 Corrected initialization of time-origin to prevent inconsistent results from ut_decode_time(). Thanks to David Pierce at the Scripps Institution of Oceanography. 2.1.11 2009-10-23 Added missing percent (%) unit. 2.1.10 2009-10-21 Fixed memory-related problems reported by valgrind(1). Changed $(pkgdatarootdir) to $(pkgdatadir) in the top-level Makefile. Corrected the syntax in the definition of the US survey foot. 2.1.9 2009-09-09 Fixed bug in ut_are_convertible() that caused it to return true for m2.s-2 and m.s-2. Changed installation directory for units database files from $(datadir) (default: /usr/local/share) to $(pkgdatadir) (default: /usr/local/share/udunits). Changed name of "ut_unit*" member in the UDUNITS-1 "utUnit" backward-compatibility structure from "ut_unit" to "unit2" because, unlike C, the g++ compiler doesn't allow a member to have the same name as a typedef. Added version specification to the top-level UDUNITS-2 documentation. 2.1.8 2009-06-19 Corrected definition of "lbf": was "2000 force_pounds"; is now "1 force_pound". 2.1.7 2009-05-05 Replaced angle brackets with quotation marks in inclusion of the UDUNITS-2 header-file by the UDUNITS-1 header-file. This was done to accomodate ncview's configure-script and because it's the right thing to do because both header-files are installed in the same directory. Added test for math library to configure script to support systems whose C library doesn't have them. Improved the process for making the "results.tab" target in the test/ subdirectory. Added delays to process for creating documentation source to accomodate broken HP-UX B.11.00 make(1). Added "make check" to git pre-commit hook. 2.1.6 2009-04-15 Added to the installed, top-level, UDUNITS-2 documentation, commentary about the existence of a version 1 C API in the package. Moved the UDUNITS-1 API into the UDUNITS-2 library subdirectory, "lib", in order to allow "make check" to build the package. 2.1.5 2009-03-24 Fixed bug in udunits2(1) utility introduced in version 2.1.2. Entering a "have" unit that didn't have a numerical first component risked a segmentation violation. 2.1.4 2009-03-24 Documented the change in meaning of the symbol "g" from the original package (standard free fall) to this package (gram). Returned HP-UX to the set of tested operating systems. 2.1.3 2009-03-23 Corrected typos in XML units database for "US_survey_foot" and "international_foot": removed embedded quotation marks. 2.1.2 2009-03-19 Corrected program udunits2(1): it now correctly parses units like "0.1 lg(re 1.0e-12 W.m-2)". Made the dimensionless unit one format as "1". Corrected rule for target "web-update": changed "distname" to "distName". Corrected the development make(1) target "hostcheck": added setting of MAKEFLAGS to the empty string before invoking make(1). 2.1.1 2009-03-13 Corrected and improved the development make(1) targets "ftp" and "download-update". Added publication of the XML database on the UDUNITS website to the target "web-update". Corrected typo in API documentation. 2.1.0 2009-03-11 Added UDUNITS-1 API. This thin interface uses the UDUNITS-2 library. Users will have to recompile their UDUNITS-1-based code using the new "udunits.h" header-file and rebuild their programs using the new UDUNITS-2 library. Because the UDUNITS-1 API uses the "utUnit" data-structure and the UDUNITS-2 API uses pointers to "ut_unit" data-structures, a small memory-leak is possible in code that creates many units. This leak can be avoided by calling the new method utFree(utUnit*) when the unit is no longer needed. Added some "const" qualifiers to the API. Modified ut_format() for timestamp units. It now prints the long form (with hyphens and colons) if the year of the origin is less than 1000 or greater than 9999. This was done to make ut_format() compatible with ut_parse(). 2.0.4 2009-02-21 Added copyright notices and LICENSE file. 2.0.3 2009-02-18 Added the function ut_root(const ut_unit* unit, int root) to return a root of a unit (e.g., "m2/s2" -> "m/s"). 2.0.2 2008-12-02 Changed order of calls to ut_set_status() and ut_handle_error_message() so that the status value is always set before the error-message handler is called. This allows error handlers to determine the cause of the message. 2.0.1 2008-11-13 Added parsing of timestamps that have dashes and colons but also use "T" (e.g., "seconds since 1970-01-01T00:00:00Z"). Corrected the regular expressions for matching the character-set specifier in the udunits2(1) program. 2.0.0 2007-07-18 Initial release. |
