LiveCode Forums.

Hi all: I am returning to LC dev after a long hiatus, so excuse me if this information has been posted in the interim an obvious place:
I am not sure which version of the LC engine I am using. When I look at About, I get something like LiveCode 8 .1 .1 | Build 14008, whereas the downloads link uses numbers like LiveCode 8 .1 .1 Indy edition STABLE, etc. How can I make absolutely sure that I am using a stable build and not some release candidate RC or DP build? Is here a master cross-referenced list of commit and build numbers somewhere? Thanks for the info...

In the IDE, see Help -> About LiveCode.

If you need to check the engine itself (from which the displayed string the in IDE is derived), see the version function, e.g.: Any non-Stable build will include the appropriate pre-release specifier in the string returned from that function (e.g. "9.6.0-rc-1").

You could also query the engine's buildNumber property and compared that to a list of versions derived from the Release Notes for the builds in this listing, but that's a lot more work and would ultimately only get you what the version function provides for you right out of the box.

As well as the sources Richard mentions, you can look directly at the page he linked to and they are explicitly laid out. Also, if you leave the updater running, you can set it to only update to stable releases in the preferences.
