2014-05-16  Kirit Saelensminde  <kirit@felspar.com>
 Add in a JSON setting store, `fostlib::settings`. Add `-j` default command line switch so that it can be used rather than an INI file.

2014-05-09  Kirit Saelensminde  <kirit@felspar.com>
 Use Boost UUID library starting with version 1.42.
 Fix a bug where bounds checking cause a build failure on platforms with unsigned char.

2014-03-21  Kirit Saelensminde  <kirit@felspar.com>

 If clang is on the path for Linux then use that in preference to gcc
 Extend the `fostlib::timestamp` and `fostlib::date` interfaces somewhat. Added a number of missing coercions and constructors to make things simpler and made sure that there is no loss in precision when converting to and from strings and JSON. Moved a number of timestamp and date members inline for speed.

2013-08-20  Kirit Saelensminde  <kirit@felspar.com>
 Added `fostlib::log::flush()` which blocks until the previous logged messages have been processed.

2013-06-07  Kirit Saelensminde  <kirit@felspar.com>
 The environment variable VERSION can now be used to specify an embedded version number in the result of fost-lib derived targets, or other shared libraries that make use of the <version> property.

 Changed a couple of exceptions to put extended data into the JSON data rather than the free form text.

2013-03-03  Kirit Saelensminde  <kirit@felspar.com>
 Changed the `what()` implementation of `fostlib::exceptions::exception` to no longer write out more than one line (unless the info member of the exception does so). Also removed the settings for controlling the format of the `what()` string.

2013-02-23  Kirit Saelensminde  <kirit@felspar.com>
 Implemented better error detail for when a JSON array is accessed out of bounds.

2013-02-23  Kirit Saelensminde  <kirit@felspar.com>

2013-02-22  Kirit Saelensminde  <kirit@felspar.com>
 Moved the file specific functions into their own header. Now include `fost/file` rather than `fost/unicode` if you only need file handling APIs. Also added a `unique_filename` function suitable for generating temporary file names.

2013-02-08  Kirit Saelensminde  <kirit@felspar.com>
 Add a `directory_iterator` typedef which allows us to iterate over wpath based directory names across all supported versions of Boost.

 Added Boost Chrono to builds on Windows for Boost 1.47 and later.

2012-11-16  Kirit Saelensminde  <kirit@felspar.com>
 Removed the `workerqueue` as it doesn't do anything useful that a work pool doesn't already do.

2012-08-17  Kirit Saelensminde  <kirit@felspar.com>
 Removed a dead constructor that does nothing in `worker`.
 No longer pass on log messages captured during tests. This stops expected errors from being displayed and confusing the test results.
 Added a basic parser for the RFC1123 formatted dates used in protocols like SMTP and HTTP. Only the format produced by the Fost libraries is currently supported.

2012-08-08  Kirit Saelensminde  <kirit@felspar.com>
 The parser lock is now recursive. This means that we can be more aggressive about using it without causing deadlocks. Also removed the parser wrapper that doesn't take a lock so all uses are explicitly forced to acquire the lock at the right time.

2012-08-04  Kirit Saelensminde  <kirit@felspar.com>
 Deliberately leak the thread counter so that it can't be destructed before threads that are terminating in a global destructor get run.

 Added startswith and endswith members to the string class.

2012-07-22  Kirit Saelensminde  <kirit@felspar.com>
 Allow time stamps and time differences to be added and subtracted.

2012-03-02  Kirit Saelensminde  <kirit@felspar.com>
 Added coercions between fostlib::json and fostlib::jcursor.

2012-02-12  Kirit Saelensminde  <kirit@felspar.com>
 Made some minor changes suggested by clang, including some dead code elimination.

2012-01-30  Kirit Saelensminde  <kirit@felspar.com>
 MSVC 10 supports stdint.h so changed the configuration to use that.

2012-01-28  Kirit Saelensminde  <kirit@felspar.com>
 Fixed up the fost-exe build target type so the fost-cli library is properly installed.

2012-01-25  Kirit Saelensminde  <kirit@felspar.com>
 Explicitly initialise some variables that were set before being returned in order to silence a compiler warning.

2012-01-24  Kirit Saelensminde  <kirit@felspar.com>

2012-01-15  Kirit Saelensminde  <kirit@felspar.com>
 Allow the logging functions to take up to four arguments.
 Allow string concatenation expressions with a narrow character literal to the left.

2012-01-09  Kirit Saelensminde  <kirit@felspar.com>
 Altered the internal cryptographic wrappers to use crypto++ instead of OpenSSL.

2011-10-27  Kirit Saelensminde  <kirit@felspar.com>
 Changed the unit testing so that it doesn't build a library any more.
 Refactored some build parameters to remove repetition.

2011-10-27  Kirit Saelensminde  <kirit@felspar.com>
 Changed the unit test runner so that it displays the output of the test run as we need to see this in order to verify that the tests do actually run.

2011-10-22  Kirit Saelensminde  <kirit@felspar.com>
 Clear out the jobs that have been taken from the queue when a major problem occurs. This should help to stop threads waiting on futures from waiting forever.

2011-10-21  Kirit Saelensminde  <kirit@felspar.com>
 Added fostlib::bytes for calculating the size of a memory block in bytes.

2011-10-09  Kirit Saelensminde  <kirit@felspar.com>

2011-04-09  Kirit Saelensminde  <kirit@felspar.com>
 The insert functions for JSON values now use a coerce rather than a JSON constructor so the API will work with more data types.

2011-03-11  Kirit Saelensminde  <kirit@felspar.com>
 Updated the build system so that there is a new fost-integration-test target that will create a test executable that can be run at any later stage as well as run the tests during the build process.

2011-03-04  Kirit Saelensminde  <kirit@felspar.com>
 The jcursor constructor can now take up to four arguments and build a cursor path from them.

2011-02-10  Kirit Saelensminde  <kirit@felspar.com>

 Added a new basic logging library.

2010-11-09  Kirit Saelensminde  <kirit@felspar.com>
 The build system now supports installation based on the location set in the PREFIX envrionment variable. If the path is relative then it is relative to the location of the Jamroot file that is being built.

2010-11-05  Kirit Saelensminde  <kirit@felspar.com>
 Added a wrapper function for boost::spirit::parse which grabs a mutex forcing serialisation of the use of the parser to get around a threading bug in Spirit.

2010-11-02  Kirit Saelensminde  <kirit@felspar.com>
 Catching of incorrect exceptions in tests now shows the full text of the caught exception.
