Hi, ohh ... sorry - I did not notice that it was commited that way. The commit window showed the inteded change on removing only the unused temp var in #newCString: as the only change. I can confirm: also the SqueakSource changeset mechanism http://www.squeaksource.com/Alien/changes/Alien-TorstenBergmann.41(RonieSalg... reveals that it changed much more than intended. Reason is also found: I used Pharo 7 for the commit as I fixed it there and as Pharo 7 image is now changed to be bootstrapped and based on our new friend "git" this unfortunately committed in Monticello without the author/timestamp. I repaired and fixed it in a new 42 version for Alien on SqueakSource, rebasing on the previous one from Ronie again: Name: Alien-TorstenBergmann.42 Author: TorstenBergmann Time: 8 January 2018, 7:52:42.082522 pm UUID: 42030335-3a5b-ad49-99e7-54889fc57194 Ancestors: Alien-RonieSalgado.40 - remove unused var in #newCString: - rebased on Alien-RonieSalgado.40.mcz  Sorry for any inconvenience this may have caused you.

But it clobbers all method stamps in the entire package. Could whoever saved this update please check this, and maybe re-save it with just Torsten's intended Alien class>>newCString: fix?  And can someone please explain what was the cause of the wiped method stamps?  _,,,^..^,,,_ best, Eliot
