## Release 1.1.0 - 2023-05-01 {#rel_1_1_0}

This is a general maintenance release.  The following bugs/issues have been fixed:

* Parameterize statements for ODBC inserts.  Add new generic DBAppender class that uses APR for database support
* Fix Qt support

## Release 1.0.0 - 2023-01-01 {#rel_1_0_0}

This is a major release that fixes a number of long-standing issues and is desinged
to make Log4cxx ABI stable moving forward.  A few notes on this version:

* Removed log4j style Java serialization.  Due to Java's inherent problems
with serialization, and the fact that Chainsaw no longer supports it, it has
been completely removed.
* A number of obsolete classes have been removed
	* Removal of TTCCLayout.  If you still want this layout, use a PatternLayout
with a format similar to the following:
`%%r [%%t] %-5p - %%m%%n`
	* Removal of DateLayout.  Use PatternLayout instead.
* Classes now use an internal private class to store member variables in order to
make them ABI stable
* Multiprocess support is available, but Log4cxx must be explicitly compiled with this option

Full release notes are below:

## Release 0.12.1 - 2021-09-21 {#rel_12_1}

This is a minor bugfix release to fix issues found with 0.12.0.  Notably, this version fixes a bug
where a multithreaded application would crash when using a rolling file.

### Bug {#rel_12_1_bugs}

-   \[[LOGCXX-534](https://issues.apache.org/jira/browse/LOGCXX-534)\] -
    Crashed in log->forcedLog function when running with multi-thread
-   \[[LOGCXX-528](https://issues.apache.org/jira/browse/LOGCXX-528)\] -
    log4cxx fails to build on Centos 7.6 / g++ 4.8.5 / Boost 1.53


## Release 0.12.0 - 2021-05-01 {#rel_12_0}

This is the first release to require a minimum version of C++11.  This means that all objects in log4cxx
are now created using `std::shared_ptr` as the smart pointer implementation.

Alternative build systems have been removed, and we now support CMake only for building the library.

With the introduction of smart pointers, the old behavior of implicit casting no longer works.  In
order to cast between classes, use the new [log4cxx::cast](@ref log4cxx.cast) method.  This method returns an invalid
`shared_ptr` on failure, or a `shared_ptr` pointing at the same object on success.  This should be
transparent to user code, unless you are interacting with log4cxx internals directly.

Before:

```{.cpp}
ObjectPtr instance = Loader::loadClass(className).newInstance();
AppenderPtr appender = instance;
```

After:

```{.cpp}
ObjectPtr instance = ObjectPtr(Loader::loadClass(className).newInstance());
AppenderPtr appender = log4cxx::cast<Appender>(instance);
// At this point(assuming the cast was good), instance and appender
// both point at the same object.
```
