Fix formatting and wording in change log

Liquid to 5.11. For now, the inclusion of Inline Snippets
in the latest Liquid release is being treated as a bug.

While #2001 does implement the scope contained in RFC#1916,
we need to take a step back to make sure we’re setting our
sights high enough with this feature, and that we’re truly
supporting theme developers in the ways they need.

If you have any feedback, please leave a comment on RFC#1916.

 # Liquid Change Log
 
+## 5.11.0
+* Revert the Inline Snippets tag (#2001), treat its inclusion in the latest Liquid release as a bug, and allow for feedback on RFC#1916 to better support Liquid developers [Guilherme Carreiro]
+* Rename the `:rigid` error mode to `:strict2` and display a warning when users attempt to use the `:rigid` mode [Guilherme Carreiro]
+
 ## 5.10.0
 * Introduce support for Inline Snippets [Julia Boutin]
-  ```
-  {%- snippet snowdevil -%}
-    Snowdevil
-  {%- endsnippet -%}
-  {% render snowdevil %}
-  ```
 
 ## 5.9.0
 * Introduce `:rigid` error mode for stricter, safer parsing of all tags [CP Clermont, Guilherme Carreiro]

-Liquid::Environment.default.error_mode = :strict # Raises a SyntaxError when invalid syntax is used in some tags
-Liquid::Environment.default.error_mode = :warn   # Adds strict errors to template.errors but continues as normal

 If you want to set the error mode only on specific templates you can pass `:error_mode` as an option to `parse`:
