+## [2.5] - 2022-09-22
+
+### Added
+
+- A new command `endl`, meaning end-line was added for line formatting sake.
+- Clang compilation is now warning-free (tested with clang 14.0).
+- Program run now optimized. Programs were parsed then linked at each run ; now the parsing and linking phases are done only once at entry time, avoiding terrible performance loss.
+
+### Changed
+
+- C++20 standard is used instead of C++17. This detected some warnings (now corrected).
+
+### Fixed
+
+- Syntax errors (and other errors) are now shown after the stack, which is much more convenient.
+- Warnings shown by clang and C++20 (braces initializers, some bad types, removed dangerous #pragma).
+- The linenoise-ng submodule version was well set in CMakeLists.txt but not in the submodule, which showed a permanent linenoise-ng modification in git although the version was the good one.
