 # barectf 2 changelog
 
+## barectf v2.3.1
+
+**Fixes**:
+
+  * Share operations between event size computation and event
+    serialization to avoid buffer overflow.
+  * Do not sample clock when closing and opening packets when this is
+    done because the current event does not fit the current packet. This
+    avoids a packet's first event having a timestamp that is less than
+    the packet's beginning timestamp.
+
+## barectf v2.3.0
+
+**Features**:
+
+  * Add tracing activity and tracing section API to check whether or not
+    the traced thread is currently within a barectf tracing function and
+    to enable or disable tracing.
+
+**Tests**:
+
+  * Add tox configuration.
+
+**Fixes**:
+
+  * Fix various testing infrastructure issues.
+  * Fix generated `bitfield.h` big-endian macros.
+
+
+## barectf v2.2.1
+
+**Minor improvements**:
+
+  * barectf now generates ANSI C code.
+  * The generated code can be compiled with a C++ compiler.
+
+**README.md**:
+
+  * barectf claims to generate ANSI C code.
+  * Reword some paragraphs.
+
+
+## barectf v2.2.0
+
+**Features**:
+
+  * Add `$default` boolean property to stream objects, and
+    `$default-stream` string property to the metadata object, to specify
+    a _default stream_: when a default stream exists, tracing function
+    aliases without the default stream name (`barectf_trace_my_event()`,
+    for example) are also generated
+  * Add `options` property to the configuration object, with:
+    * `gen-prefix-def`: true to generate a preprocessor definition
+      (`#define`) in `barectf.h` for the effective prefix
+    * `gen-default-stream-def`: true to generate a preprocessor
+      definition for the default stream name, if any
+  * Create `barectf-tracepoint.h`, a bridging C header file that
+    allows LTTng-UST tracepoints to be used as is with barectf by
+    providing the same `tracepoint()` macro
+
+**Tests**:
+
+  * Test the new `$default` (stream object), `$default-stream` (metadata
+    object), and `options` (configuration object) properties
+
+**README.md**:
+
+  * Add instructions for installing barectf on Arch Linux using the AUR
+  * Add instructions for installing barectf on Ubuntu using a PPA
+
+
 ## barectf v2.1.4
 
 **Minor improvements**:
