Though there were otherwise just cosmetic changes made to the SDK version 11 "Lightroom Classic Programmers Guide", there was one serious mistake. On page 9, as part of changing occurrences of "Lightroom" to "Lightroom Classic", this sentence from previous versions was deleted:
"Lightroom 5 uses version 5.1.4 of the Lua language."
That sentence should be retained and edited to say:
"Lightroom Classic uses version 5.1.4 of the Lua Language"
It's very important to tell plugin developers which version the SDK uses because:
- The mainstream Lua release is now Lua 5.4.3 and there are significant differences between 5.1.4 (the version LR uses) and 5.4.3.
- Most programmers coming to the SDK aren't familiar with Lua and will get confused when they read documentation for the wrong version.
