CHANGELOG.md

 ## 1.23.0
 
 ### Language
 * Allow using URI strings in `part of` declarations to refer to the
   importing library.
 
 ### Core library changes
-* `dart:core`: Added `Uri.isScheme` function to check the scheme of a URI.
-   Example: `uri.isScheme("http")`. Ignores case when comparing.
-* `dart:core`: Make `UriData.parse` validate its input better.
-  If the data is base-64 encoded, the data is normalized wrt.
-  alphabet and padding, and it contains invalid base-64 data,
-  parsing fails. Also normalizes non-base-64 data.
-* `dart:io`: Added functions `File.lastAccessed`, `File.lastAccessedSync`,
-  `File.setLastModified`, `File.setLastModifiedSync`, `File.setLastAccessed`,
-  and `File.setLastAccessedSync`.
-* `dart:io`: Added `Platform.ansiSupported`.

 ### Dart VM
 * Calls to `print()` and `Stdout.write*()` now correctly print unicode
   characters to the console on Windows. Calls to `Stdout.add*()` behave as
   before.
 
 ### Tool changes
 
 * Analysis
-
-  * The `dartanalyzer` now follows the same rules as the analysis server to find an analysis options file,
-    stopping when an analysis options file is found:

-      and that file will be used instead of searching for an analysis options file.
-    * any analysis option specified on the command line (e.g. `--strong` or `--no-strong`)
-      takes precedence over any corresponding value specified in the analysis options file.

What does it do on benchmark/ and example/?

[kevmoo, 2017/03/17 20:11:01]

Nothing yet. https://github.com/dart-lang/pub/issues/1537

+    * No longer produces "UID too large" errors on OS X. All packages are now
+      uploaded with the user and group names set to "pub".
+    * No longer fails with a stack overflow when uploading a package that uses
+      Git submodules.
+  * `pub get` and `pub upgrade`
+    * Produce more informative error messages if they're run directly in a
+      package that uses Flutter.
+    * Properly unlock SDK and path dependencies if they have a new version
+      that's also valid according to the user's pubspec.
 
 ## 1.22.0
 
 ### Language
 
-  * Breaking change: ['Generalized tear-offs'](https://github.com/gbracha/generalizedTearOffs/blob/master/proposal.md)

     are no longer supported, and will cause errors. We updated the language spec
     and added warnings in 1.21, and are now taking the last step to fully
     de-support them. They were previously only supported in the VM, and there
     are almost no known uses of them in the wild.
 
   * The `assert()` statement has been expanded to support an optional second
-    `message` argument (SDK issue [27342](https://github.com/dart-lang/sdk/issues/27342)).
+    `message` argument 
+    (SDK issue [27342](https://github.com/dart-lang/sdk/issues/27342)).
 
     The message is displayed if the assert fails. It can be any object, and it
     is accessible as `AssertionError.message`. It can be used to provide more
     user friendly exception outputs. As an example, the following assert:
 
     ```dart
     assert(configFile != null, "Tool config missing. Please see https://goo.gl/k8iAi for details.");
     ```
 
     would produce the following exception output:
@@ skipping 1640 matching lines @@
     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.
