+
+
+### Bug Fixes
+
+* Tweak package.json files for republish as latest 1.x. ([#217](https://github.com/istanbuljs/istanbuljs/issues/217)) ([420481d](https://github.com/istanbuljs/istanbuljs/commit/420481d)), closes [#216](https://github.com/istanbuljs/istanbuljs/issues/216)
+
+
+### BREAKING CHANGES
+
+* leaked into 1.x modules but it was thought they were
+never released to latest.  Apparently releasing 2.x to latest makes
+those unwanted versions of 1.x available.
+
+This patch sets all modules to the latest 1.x version (4.x for
+test-exclude).  This will allow a new release to be made to revert
+release of the breaking changes.
+
+Stop upgrading npm to latest for testing as it's not compatible with
+node 4.x.

+## Extend
+You can simply extend debugger 
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');

+## Set dynamically

+You can also enable debug dynamically by calling the `enable()` method :

+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));

+Usage :  
+`enable(namespaces)`  
+`namespaces` can include modes separated by a colon and wildcards.

+Note that calling `enable()` completely overrides previously set DEBUG variable :
