 ## Changelog

+### 0.9.3 (2021-04-26)
+
+* Upgrade Go version to 1.16.3, alpine to 3.13 and other dependencies.
+* Support deletion of manifest lists.
+
+### 0.9.2 (2020-07-10)
+
+* Upgrade Go version to 1.14.4, alpine to 3.12 and other dependencies.
+* Enable default logging for purge tags task.
+
+### 0.9.1 (2020-02-20)
+
+* Minor amendments for the tag info page to account the cache type of sub-image.
+
+### 0.9.0 (2020-02-19)
+
+* Upgrade Go version to 1.13.7, alpine to 3.11 and other dependencies.
+* Support Manifest List v2. This enables the proper display of multi-arch images,
+  such as those generated by Docker BuildX or manually (thanks to Christoph Honal @StarGate01).
+  So now we support the following formats: Manifest v2 schema 1, Manifest v2 schema 2, Manifest List v2 schema 2
+  and all their confusing combinations.
+* Amend representation of the tag info page.
+* Change logging library, add "-log-level" argument and put most of the logging into DEBUG mode.
+* You can define timezone when running container by adding `TZ` env var, e.g. "-e TZ=America/Los_Angeles"
+  (thanks to @gminog).
+* Fix initial ownership of /opt/data dir in Dockerfile.
+* Hide repositories with 0 tags count.
+* Compatibility fix with docker_auth v1.5.0.
+
+### 0.8.2 (2019-07-30)
+
+* Add event_deletion_enabled option to the config, useful for master-master/cluster setups.
+* Generate SHA256 from response body if no Docker-Content-Digest header is present, e.g. with AWS ECR.
+* Bump go version.
+
+### 0.8.1 (2019-02-20)
+
+* Add favicon.
+
+### 0.8.0 (2019-02-19)
+
+* Use go 1.11.5, alpine 3.9, echo 3.3.10.
+* Put all static files to the docker image instead of loading from CDN.
+* Now discover more than 100 repositories (thanks to Yuhi Ishikura @uphy).
+
 ### 0.7.4 (2018-10-30)

 * Switch to Go 1.11 and Go Modules to track dependencies.

+### About Docker image formats...
+
+Docker image formats and their confusing combinations as supported by this UI:
+
+* Manifest v2 schema 1 only: older format, e.g. created with Docker 1.9.
+* Manifest v2 schema 1 + Manifest v2 schema 2: current format of a single image, the image history are coming from schema 1, should be referenced by repo:tag name.
+* Manifest v2 schema 1 + Manifest List v2 schema 2: multi-arch image format containing digests of sub-images, the image history are coming from schema 1 (no idea from what sub-image it was picked up when created), should be referenced by repo:tag name.
+* Manifest v2 schema 2: current image format referenced by its digest sha256, no image history.
+* Manifest List v2 schema 2: multi-arch image referenced by its digest sha256 or cache image referenced by tag name, no image history.

+/**
+ * Data can often be a complicated mix of numbers and letters (file names
+ * are a common example) and sorting them in a natural manner is quite a
+ * difficult problem.
+ * 
+ * Fortunately a deal of work has already been done in this area by other
+ * authors - the following plug-in uses the [naturalSort() function by Jim
+ * Palmer](http://www.overset.com/2008/09/01/javascript-natural-sort-algorithm-with-unicode-support) to provide natural sorting in DataTables.
+ *
+ *  @name Natural sorting
+ *  @summary Sort data with a mix of numbers and letters _naturally_.
+ *  @author [Jim Palmer](http://www.overset.com/2008/09/01/javascript-natural-sort-algorithm-with-unicode-support)
+ *  @author [Michael Buehler] (https://github.com/AnimusMachina)
+ *
+ *  @example
+ *    $('#example').dataTable( {
+ *       columnDefs: [
+ *         { type: 'natural', targets: 0 }
+ *       ]
+ *    } );
+ *
+ *    Html can be stripped from sorting by using 'natural-nohtml' such as
+ *
+ *    $('#example').dataTable( {
+ *       columnDefs: [
+ *    	   { type: 'natural-nohtml', targets: 0 }
+ *       ]
