@ -363,8 +363,29 @@ xa-2.3.11
-- Cameron Kaiser <ckaiser@floodgap.com> 4 May 2020
xa-2.3.12
* Regression fix for address size validation in 65816 mode (thanks Sam
Falvo; we had a pending fix for this but I like his test case).
* Testsuite expanded.
-- Cameron Kaiser <ckaiser@floodgap.com> 26 November 2021
xa-2.3.13
* Fix // and /* */ in quoted strings. Incredible no one ever hit this
before (thanks ZornsLemma).
* Segfault fixes for file65, reloc65 and xa. Remember, kids, if you ever
run xa as root all kittens will die. Please save the kittens (thanks
Stephen Kitt).
* Just compare to null in the preprocessor (thanks Bas Wassink).
* Testsuite expanded.
-- Cameron Kaiser <ckaiser@floodgap.com> 25 March 2022
xa-2.x.x
* Listing feature
* Add -E commandline option to not stop after 20 errors, but show all
of them
* Introduce -X compatibility set commandline option, to distinguish
