+### Custom plugins that used shared Redis config
+
+In 3.8.0.0 version we have changed and refactored the shared Redis configuration that previously was imported by `require "kong.enterprise_edition.redis"`. If you have created a custom plugin that is using this shared configuration or if you have a forked version
+of a plugin (ex. `rate-limiting-advanced`) then there might be additional steps that would require you to upgrade to version 2 of this Redis config.
+
+Out of the box the custom plugins should still be working since the old shared configuration was left in place. The new config adds `cluster_max_redirections` option for Redis Cluster and the format of `cluster_nodes` and
+`sentinel_nodes` has been changed. Apart from that - the intialization step is not required anymore.
+
+#### Shared Redis Config: How to upgrade custom plugins
+
+If your plugin is using shared Redis config - i.e. you import: `require "kong.enterprise_edition.redis"` you should do the following steps:
+
+1. Remove library intialization call: `redis.init_conf(conf)` - where `redis` is `local redis = require "kong.enterprise_edition.redis"`
+2. Switch the imports of redis from `local redis = require "kong.enterprise_edition.redis"` to `local redis = require "kong.enterprise_edition.tools.redis.v2"`
+
+#### Rate-Limiting library: How to upgrade custom plugins
+
+If your plugin is using Rate-Limiting library - i.e. you import `local ratelimiting = require("kong.tools.public.rate-limiting").new_instance("your-plugin-name")` you should do the following steps:
+
+1. Switch the imports of:
+    1. Shared Redis config: `local redis = require "kong.enterprise_edition.redis"` to `local redis = require "kong.enterprise_edition.tools.redis.v2"`
+    2. Rate-Limiting library: `local ratelimiting = require("kong.tools.public.rate-limiting").new_instance("your-plugin-name")` to `local ratelimiting = require("kong.tools.public.rate-limiting").new_instance("your-plugin-name", { redis_config_version = "v2" })`
