+# Changes in build system
+
+- Extended `rake install` task ([#5928](https://github.com/mruby/mruby/pull/5928)) <br>
+  **_NOTE_**: Due to this impact, executable files in the `mruby/bin/` directory by default are now symbolic links (batch files on Windows).
+  If previously relied on those executables, should be replaced with direct references to the entity created under the build directory (e.g. `mruby/build/host/bin/`).
+- Encode and decode escape characters for presym ([#6011](https://github.com/mruby/mruby/pull/6011))
+- Rakefile: remove default build target directories in `deep_clean` ([#6032](https://github.com/mruby/mruby/pull/6032), [1e38569](https://github.com/mruby/mruby/commit/1e38569))
+
+# Other breaking changes
+
+- `mrb_f_raise()` is now an internal function
+  ([#5923](https://github.com/mruby/mruby/pull/5923), [#6070](https://github.com/mruby/mruby/pull/6070))
+- `mrb_make_exception()` is now an internal function with different parameters
+  ([431f83e](https://github.com/mruby/mruby/commit/431f83e), [78137f3](https://github.com/mruby/mruby/commit/78137f3))
+- The `File#path` method no longer uses the `#to_path` method for implicit conversion
+  ([d86c4a7](https://github.com/mruby/mruby/commit/d86c4a7))
+- stop mrb isolation for each test file ([a20fbe5](https://github.com/mruby/mruby/commit/a20fbe5))
+- RBreak remembers the CI location ([#6103](https://github.com/mruby/mruby/pull/6103))
