 EduMIPS64 is a GPL MIPS64 Instruction Set Architecture (ISA) simulator and graphical debugger.
 
 ## Notes for this release
 
-This is version 1.2.8 of EduMIPS64. Its codename is NLMS, to remember my late father
-Nicola Luigi Maria Spadaccini, who left us last month.
+This is version 1.2.9 of EduMIPS64. Its codename is Baby Shark, because my
+brain is overloaded with the song thanks to my son, and for some reason this
+is the only name that comes to mind right now.
 
-This version contains a few bug fixes (including a fix for the LUI
-instruction which was completely broken) and a new experimental CLI interface
-(which you can enter by using the `--headless` command-line flag).
-
-This is also the first version to be distributed as a Windows MSI installer, which contains
-a JRE and everything you need to run the simulator on Windows without needing external
-dependencies. As usual, the simulator is also distributed as a JAR and via the Snapcraft store.
+This version contains 2 major bug fixes, one for the LUI instruction, which in 1.2.8 was not
+completely fixed, and another for the in-app manual, which was not displayed correctly
+in some platforms.
