 ## 1.10.0 – 2015-04-29
 
 ### Core library changes
 
 * `dart:convert`
-  * Fix behavior of `HtmlEscape`. It no longer escapes
+  * **POTENTIALLY BREAKING** Fix behavior of `HtmlEscape`. It no longer escapes
   no-break space (U+00A0) anywhere or forward slash (`/`, `U+002F`) in element
   context. Slash is still escaped using `HtmlEscapeMode.UNKNOWN`.

+  * **POTENTIALLY BREAKING** `CssClassSet` method arguments must now be 'tokens', i.e. non-empty
   strings with no white-space characters. The implementation was incorrect for
   class names containing spaces. The fix is to forbid spaces and provide a
   faster implementation.

+* `dart:io`

+
+## Tool Changes
+
+### pub
+
+  * Running `pub run foo` within a package now runs the `foo` executable defined
+    by the `foo` package. The previous behavior ran `bin/foo`. This makes it
+    easy to run binaries in dependencies, for instance `pub run test`.
+
+  * On Mac and Linux, signals sent to `pub run` and forwarded to the child
+    command.
 
 ## 1.9.3 – 2015-04-14
 
 This is a bug fix release which merges a number of commits from `bleeding_edge`.

     they will keep the Dart process alive until they time out. This fixes the
     handling of persistent connections. Previously, the client would shut down
     immediately after a request.
 
   * **Breaking change:** `HttpServer` no longer compresses all traffic by
     default. The new `autoCompress` property can be set to `true` to re-enable
     compression.
 
 * `dart:isolate`: `Isolate.spawnUri` added the optional `packageRoot` argument,
   which controls how it resolves `package:` URIs.
