+*   Deprecate using negative limits in `String#first` and `String#last`.
+
+    *Gannon McGibbon*, *Eric Turner*
+
+*   Fix bug where `#without` for `ActiveSupport::HashWithIndifferentAccess` would fail
+    with symbol arguments
+
+    *Abraham Chan*
+
+*   Treat `#delete_prefix`, `#delete_suffix` and `#unicode_normalize` results as non-`html_safe`.
+    Ensure safety of arguments for `#insert`, `#[]=` and `#replace` calls on `html_safe` Strings.
+
+    *Janosch Müller*
+
+*   Changed `ActiveSupport::TaggedLogging.new` to return a new logger instance instead
+    of mutating the one received as parameter.
+
+    *Thierry Joyal*
+
+*   Define `unfreeze_time` as an alias of `travel_back` in `ActiveSupport::Testing::TimeHelpers`.
+
+    The alias is provided for symmetry with `freeze_time`.
+
+    *Ryan Davidson*
+
+*   Add support for tracing constant autoloads. Just throw

+        ActiveSupport::Dependencies.logger = Rails.logger
+        ActiveSupport::Dependencies.verbose = true

+
+*   Maintain `html_safe?` on html_safe strings when sliced.
+
+        string = "<div>test</div>".html_safe
+        string[-1..1].html_safe? # => true
+
+    *Elom Gomez*, *Yumin Wong*
+
+*   Add `Array#extract!`.
+
+    The method removes and returns the elements for which the block returns a true value.
+    If no block is given, an Enumerator is returned instead.
+
+        numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
+        odd_numbers = numbers.extract! { |number| number.odd? } # => [1, 3, 5, 7, 9]
+        numbers # => [0, 2, 4, 6, 8]
+
+    *bogdanvlviv*

 *   Support not to cache `nil` for `ActiveSupport::Cache#fetch`.

     `Range#cover?` can now accept a range argument like `Range#include?` and
     `Range#===`. `Range#===` works correctly on Ruby 2.6. `Range#include?` is moved
