+Version 0.11.0
+
+ * Initial work on header unit importation and include translation support.
+
+   In particular, for GCC, the module mapper approach is now used to handle
+   header unit importation, include translation, and headers dependency
+   extraction, all with support for auto-generated headers.
+
+ * Generalized target/prerequisite variable blocks.
+
+   Target/prerequisite-specific variable blocks can now be present even if
+   there are prerequisites. For example, now instead of:
+
+   exe{foo}: cxx{foo}
+   exe{foo}: cc.loptions += -rdynamic
+
+   Or:
+
+   exe{foo}: cxx{foo}
+   exe{foo}:
+   {
+     cc.loptions += -rdynamic
+     cc.libs += -ldl
+   }
+
+   We can write:
+
+   exe{foo}: cxx{foo}
+   {
+     cc.loptions += -rdynamic
+     cc.libs += -ldl
+   }
+
+   This also works with dependency chains in which case the block applies
+   to the set of prerequisites (note: not targets) before the last ':'. For
+   example:
+
+   ./: exe{foo}: libue{foo}: cxx{foo}
+   {
+     bin.whole = false  # Applies to the libue{foo} prerequisite.
+   }
+
+ * Support for ad hoc target groups.
+
+   In certain cases we may need to instruct the underlying tool (compiler,
+   linker, etc) to produce additional outputs. For example, we may want to
+   request the compiler to produce an assembler listing and a linker to
+   produce a map file. While we can pass the required options, the resulting
+   files will not be part of the build state. Specifically, they will not be
+   cleaned and we cannot use them as prerequisites of other targets.
+
+   Ad hoc target groups allow us to specify that updating a target produces
+   additional outputs, called ad hoc group members. For example:
+
+   <exe{hello} file{hello.map}>: cxx{hello}
+   {
+     cc.loptions += "-Wl,-Map=$out_base/hello.map"
+   }
+
+   <obje{hello} file{hello.lst}>:
+   {
+     cc.coptions += "-Wa,-amhls=$out_base/hello.lst"
+   }
+
+   Note also that all things ad hoc (prerequisites, targets, rules) are still
+   under active development so further improvements (such as not having to
+   repeat names twice) are likely.
+
+ * New config.{c,cxx}.std configuration variables that, if present, override
+   {c,cxx}.std specified at the project level.
+
+   In particular, this allows forcing a specific standard for all the projects
+   in a build configuration, for example:
+
+   $ b create: exp-conf/,cc config.cxx=g++ config.cxx.std=experimental
+
+ * New --dry-run|-n option instructs build rules to print command without
+   actually executing them.
+
+   Note that commands that are required to create an accurate build state will
+   still be executed and the extracted auxiliary dependency information saved.
+   In other words, this is not the "don't touch the filesystem" mode but
+   rather "do minimum amount of work to show what needs to be done". In
+   particular, this mode is useful to quickly generate the compilation
+   database, for example:
+
+   $ b -vn clean update |& compiledb
+
+ * Ability to disable automatic rpath, support for custom rpath-link.
+
+   Specifically, the new config.bin.rpath.auto variable can be used to disable
+   automatic addition of prerequisite library rpaths, for example:
+
+   $ b config.bin.rpath.auto=false
+
+   Note that in this case rpath-link is still added where normally required
+   and for target platforms that support it (Linux and *BSD).
+
+   The new config.bin.rpath_link and config.bin.rpath_link.auto have the same
+   semantics as config.bin.rpath* but for rpath-link.
+
+ * Enable MSVC strict mode (/permissive-) for experimental standard starting
+   from version 15.5.
+
 Version 0.10.0
 
  * Support for an alternative build file/directory naming scheme.
