+h4. Stricter collection manifest validation on the API server
+
+As a consequence of "#14482":https://dev.arvados.org/issues/14482, the Ruby SDK does a more rigorous collection manifest validation. Collections created after 2015-05 are unlikely to be invalid, however you may check for invalid manifests using the script below.
+
+You could set up a new rvm gemset and install the specific arvados gem for testing, like so:
+
+<notextile>
+<pre><code>~$ <span class="userinput">rvm gemset create rubysdk-test</span>
+~$ <span class="userinput">rvm gemset use rubysdk-test</span>
+~$ <span class="userinput">gem install arvados -v 1.3.1.20190301212059</span>
+</code></pre>
+</notextile>
+
+Next, you can run the following script using admin credentials, it will scan the whole collection database and report any collection that didn't pass the check:
+
+{% codeblock as ruby %}
+require 'arvados'
+require 'arvados/keep'
+
+api = Arvados.new
+offset = 0
+batch_size = 100
+invalid = []
+
+while true
+ begin
+ req = api.collection.index(
+ :select => [:uuid, :created_at, :manifest_text],
+ :include_trash => true, :include_old_versions => true,
+ :limit => batch_size, :offset => offset)
+ rescue
+ invalid.each {|c| puts "#{c[:uuid]} (Created at #{c[:created_at]}): #{c[:error]}" }
+ raise
+ end
+
+ req[:items].each do |col|
+ begin
+ Keep::Manifest.validate! col[:manifest_text]
+ rescue Exception => e
+ puts "Collection #{col[:uuid]} manifest not valid"
+ invalid << {uuid: col[:uuid], error: e, created_at: col[:created_at]}
+ end
+ end
+ puts "Checked #{offset} / #{req[:items_available]} - Invalid: #{invalid.size}"
+ offset += req[:limit]
+ break if offset > req[:items_available]
+end
+
+if invalid.empty?
+ puts "No invalid collection manifests found"
+else
+ invalid.each {|c| puts "#{c[:uuid]} (Created at #{c[:created_at]}): #{c[:error]}" }
+end
+{% endcodeblock %}
+
+The script will return a final report enumerating any invalid collection by UUID, with its creation date and error message so you can take the proper correction measures, if needed.

h4. Python packaging change
As part of story "#9945":https://dev.arvados.org/issues/9945, the distribution packaging (deb/rpm) of our Python packages has changed. These packages now include a built-in virtualenv to reduce dependencies on system packages. We have also stopped packaging and publishing backports for all the Python dependencies of our packages, as they are no longer needed.
As part of story "#9945":https://dev.arvados.org/issues/9945, it was discovered that the Centos7 package for libpam-arvados was missing a dependency on the python-pam package, which is available from the EPEL repository. The dependency has been added to the libpam-arvados package. This means that going forward, the EPEL repository will need to be enabled to install libpam-arvados on Centos7.
+h4. New configuration
+
+Arvados is migrating to a centralized configuration file for all components. During the migration, legacy configuration files will continue to be loaded. See "Migrating Configuration":config-migration.html for details.
+
h3. v1.3.0 (2018-12-05)
This release includes several database migrations, which will be executed automatically as part of the API server upgrade. On large Arvados installations, these migrations will take a while. We've seen the upgrade take 30 minutes or more on installations with a lot of collections.
