+## v0.8.8 - 2017-10-24 - Google Cloud DNS, Large TXT Record support
+
+* Added support for "chunking" TXT records where individual values were larger
+  than 255 chars. This is common with DKIM records involving multiple
+  providers.
+* Added `GoogleCloudProvider`
+* Configurable `UnsafePlan` thresholds to allow modification of how many
+  updates/deletes are allowed before a plan is declared dangerous.
+* Manager.dump bug fix around empty zones.
+* Prefer use of `.` over `source` in shell scripts
+* `DynProvider` warns when it ignores unrecognized traffic directors.
+
+## v0.8.7 - 2017-09-29 - OVH support
+
+Adds an OVH provider.
+
+## v0.8.6 - 2017-09-06 - CAA record type,
+
+Misc fixes and improvments.
+
+* Azure TXT record fix
+* PowerDNS api support for https
+* Configurable Route53 max retries and max-attempts
+* Improved key ordering error message
+
 ## v0.8.5 - 2017-07-21 - Azure, NS1 escaping, & large zones
 
 Relatively small delta this go around. No major themes or anything, just steady
