+{% assign release = site.data.releases | where: "version", "3.4.0-preview1" | first %}
+We are pleased to announce the release of Ruby {{ release.version }}.
+
+## Language changes
+
+* String literals in files without a `frozen_string_literal` comment now behave
+  as if they were frozen. If they are mutated a deprecation warning is emitted.
+  These warnings can be enabled with `-W:deprecated` or by setting `Warning[:deprecated] = true`.
+  To disable this change, you can run Ruby with the `--disable-frozen-string-literal`
+  command line argument. [[Feature #20205]]
+
+* `it` is added to reference a block parameter. [[Feature #18980]]
+
+* Keyword splatting `nil` when calling methods is now supported.
+  `**nil` is treated similarly to `**{}`, passing no keywords,
+  and not calling any conversion methods.  [[Bug #20064]]
+
+* Block passing is no longer allowed in index.  [[Bug #19918]]
+
+* Keyword arguments are no longer allowed in index.  [[Bug #20218]]
+
+## Core classes updates
+
+Note: We're only listing outstanding class updates.
+
+* Exception
+
+  * Exception#set_backtrace now accepts arrays of `Thread::Backtrace::Location`.
+    `Kernel#raise`, `Thread#raise` and `Fiber#raise` also accept this new format. [[Feature #13557]]
+
+* Range
+
+  * Range#size now raises TypeError if the range is not iterable. [[Misc #18984]]
+
+
+
+## Compatibility issues
+
+Note: Excluding feature bug fixes.
+
+* Error messages and backtrace displays have been changed.
+  * Use a single quote instead of a backtick as a opening quote. [[Feature #16495]]
+  * Display a class name before a method name (only when the class has a permanent name). [[Feature #19117]]
+  * `Kernel#caller`, `Thread::Backtrace::Location`'s methods, etc. are also changed accordingly.
+  ```
+  Old:
+  test.rb:1:in `foo': undefined method `time' for an instance of Integer
+          from test.rb:2:in `<main>'
+
+  New:
+  test.rb:1:in 'Object#foo': undefined method 'time' for an instance of Integer
+          from test.rb:2:in `<main>'
+  ```
+
+
+## C API updates
+
+* `rb_newobj` and `rb_newobj_of` (and corresponding macros `RB_NEWOBJ`, `RB_NEWOBJ_OF`, `NEWOBJ`, `NEWOBJ_OF`) have been removed. [[Feature #20265]]
+* Removed deprecated function `rb_gc_force_recycle`. [[Feature #18290]]
+
+## Implementation improvements
+
+* `Array#each` is rewritten in Ruby for better performance [[Feature #20182]].
+
+## Miscellaneous changes
+
+* Passing a block to a method which doesn't use the passed block will show
+  a warning on verbose mode (`-w`).
+  [[Feature #15554]]
+
+* Redefining some core methods that are specially optimized by the interpeter
+  and JIT like `String.freeze` or `Integer#+` now emits a performance class
+  warning (`-W:performance` or `Warning[:performance] = true`).
+  [[Feature #20429]]
