 The Dockerfile is the basis of the devcontainer and can be changed to add or remove tools. It will take a long time to build locally, so by default the devcontainer will pull a prebuilt version. Edit `.devcontainer/devcontainer.json` if you would rather build your own.
 
 The devcontainer contains:
 - pasmo version 0.5.3 (assembler)
-- sjasmplus version 1.23.0 (assembler)
+- sjasmplus version 1.23.1 (assembler)
 - z80asm version 1.8 (assembler)
 - z80dasm version 1.1.6 (disassembler)
 - zmakebas version 1.2b (creates BASIC programs)

+Minor version update for sjasmplus.
