0.6.0 - 11-Dec-2011

• Switched Unix code to use FFI.

• Removed all of the C related tasks from the Rakefile and added the gem:build and gem:install tasks.

• Internal directory layout changes, with appropriate changes to the gemspec.

0.5.3 - 7-May-2009

• Altered the Uptime.seconds implementation on Linux so that it works with both Ruby 1.8.x and 1.9.x. Thanks go to Alexey Chebotar for the spot.

0.5.2 - 13-Dec-2008

• Fixed a date/time issue in the Windows version caused by Ruby itself.

• Fixed the Uptime.seconds, Uptime.minutes and Uptime.hours methods on MS Windows.

• Renamed the test file to 'test_sys_uptime.rb'.

• Some minor updates to the Rakefile.

0.5.1 - 26-Jul-2007

• Fixed bug in the MS Windows version caused by incorrect parsing of an MS specific date format (caused by a bug in Ruby 1.8.6). Thanks go to Robert H. for the spot.

• Inlined the Rake installation tasks, so the install.rb file has been removed.

• Added an 'install_gem' Rake task, and updated the README installation instructions.

0.5.0 - 30-Mar-2007

• For platforms that use C code, the code now always uses the sysctl() function if supported by your system. This replaces the platform specific checks I was doing for the various BSD flavors.

• Fix for OS X - the Uptime.boot_time method now works.

• UptimeError is now Uptime::Error.

• Improved RDoc in the uptime.c source code.

• Added a Rakefile - users should now use the 'test' and 'install' rake tasks.

• Updates to the MANIFEST, README and uptime.txt files.

0.4.5 - 19-Nov-2006

• Internal layout changes, minor doc updates and gemspec improvements.

• No code changes.

0.4.4 - 30-Jun-2006

• Added inline rdoc documentation to the source files.

• Added a gemspec.

0.4.3 - 18-Dec-2005

• Changed the Linux version to pure Ruby. The current method of determining uptime in unix.c does not work in Linux kernel 2.6+. So, from now on it reads out of /proc/uptime.

0.4.2 - 6-May-2005

• Fixed a potential boot_time bug.

• Removed the version.h file. It's no longer needed since the Windows version is pure Ruby.

• NetBSD 2.x and FreeBSD 5.x now supported.

• Removed the INSTALL file. Installation instructions are now in the README file.

• Removed the uptime.rd file. You can generate html documentation by running rdoc over the uptime.txt file.

• Made most documents rdoc friendly.

• Moved project to RubyForge.

0.4.1 - 14-Dec-2004

• Moved freebsd code into unix.c file.

• Should now work past 249 days (2**31) on systems that have utmpx.h.

• Fixed a bug with regards to boot_time, where it was possible that it would simply be empty.

0.4.0 - 8-Jul-2004

• Removed all reference to the CLK_TCK constant, as per documentation from Richard Stevens that it is deprecated and that sysconf() should be used instead (well, I knew about this, but ignored it until now).

• Scrapped the C version for Windows in favor of a pure Ruby version that uses win32ole + WMI.

• Added a boot_time method for Unix systems (Windows already had this).

• Added an UptimeError class on Unix systems (and replaced UptimeException on Windows).

• Modified an internal function to raise an UptimeError if the times() function fails. Also, it now returns an unsigned long instead of a plain long.

• Replaced the two different test suites with a single, unified test suite.

• Cleaned up the extconf.rb script. I now assume that TestUnit is installed.

• Removed the load_avg method (which was never advertised and which I hope you weren't using). You can find a load_avg method in the sys-cpu package.

• Changed uptime.rd2 to uptime.rd to be consistent with my other packages.

• Removed the uptime.html file - you may generate that on your own.

• Added warranty and license info.

0.3.2 - 30-Dec-2003

• Cleaned up some warnings that showed up with -Wall on some unix platforms (int vs long format, explicit include)

• Minor test suite and extconf.rb changes

0.3.1 - 25-Jun-2003

• Modified test files to handle HP-UX extensions

• Minor doc updates

• Added the dhms() method. Actually, this was in the 0.3.0 release, I just forgot to mention it in this file :)

0.3.0 - 22-Jun-2003

• Added OS X support - thanks go to Mike Hall for the patch

• Fixed incorrect values in FreeBSD (again Mike Hall)

• Modified tc_unix.rb test suite to handle OS X, along with a bit

• of minor cleanup

• Removed VERSION class method. Use the constant instead

• Separated FreeBSD/OS X source into its own file (freebsd.c). The ifdefs were starting to get too ugly for me

0.2.1 - 13-May-2003

• Fixed bug in extconf.rb file, and made some major changes

• Modified test.rb for those without TestUnit

• Modified TestUnit tests - some bogus tests were removed

• Added a README file with some additional info

• Created a version.h file, so that I can keep the VERSION number in one place

• Docs automatically included in doc directory (i.e. no more interactive document creation)

0.2.0 - 13-Mar-2003

• Added MS Windows support

• Added a VERSION constant

• Added a test suite (for those with TestUnit installed)

• Internal directory layout change

• uptime.c is now split into unix.c and windows.c (and linked appropriately)

• Changelog and Manifest are now CHANGES and MANIFEST, respectively

• Many changes to extconf.rb

0.1.3 - 6-Jan-2003

• Added a VERSION class method

• Added a copyright notice

• Fixed up the docs a bit and moved them to the doc directory

• Changed the tarball name to match the RAA package name

• Modified test.rb script to make it better

• Changed install instructions slightly

0.1.2 - 25-Aug-2002

• Slight change to preprocessor commands to avoid redefining CLK_TCK on those systems that define it in time.h

• Added an INSTALL file

0.1.1 - 21-Jun-2002

• The CLK_TCK constant wasn't necessarily being set correctly, which could lead to some odd results. This has been fixed.

0.1.0 - 17-Jun-2002

• Initial release
