| Added a few new formatters, called character decorators. These can be useful |
| to post-process the formatted output before passing it on to the sink. |
| </li> |
| <li class="listitem"> |
| Added attributes for thread and process identifiers. These identifiers |
| are automatically added after the call to <code class="computeroutput"><span class="identifier">add_common_attributes</span></code>. |
| </li> |
| <li class="listitem"> |
| Helper initialization functions, such as <code class="computeroutput"><span class="identifier">init_log_to_file</span></code> |
| now accept more customization options as named arguments. |

| <li class="listitem"> |
| A new <a class="link" href="detailed/utilities.html#log.detailed.utilities.setup.settings" title="Library initialization from a settings container">initialization |
| interface</a> has been exposed. One can fill a settings container and |
| use it to initialize the library. |
| </li> |
| <li class="listitem"> |
| The library setup support code has been extracted into a separate binary. |
| Further on, this binary will be made optional to build. |
| </li> |
| <li class="listitem"> |
| Added a new mode of logging, called trivial logging. In this mode the library |
| requires no initialization at all, however it does not offer many ways |
| of customization. |
| </li> |
| <li class="listitem"> |
| A number of bugs fixed. |
| </li> |
| <li class="listitem"> |
| A few optimizations added to improve multithreaded applications performance. |
| </li> |
| <li class="listitem"> |
| Removed some bug workarounds for older Boost releases. The library now |
