Hi. I am not sure what is happening here with the other 32 commits. It may be that I screed up something in my rebaselining. Let me check.

[vowstar]

@TerryE I have remove all version information including how http module is build, and combine all commits to 1 now.

#887

[vowstar]

@TerryE 25af2b9 d34ac77 50dcea3 is discarded by 5b6acee, and 5b6acee is equivalent to a8359f1 because it merge from /dev and overrite all old version. From 0380e49 to 0c8e1a2 is the process to build http module.

@vowstar I am just trying to get our SDK 1.5-based dev stable. Do you mind if we delay merging in this for a few days? Doing both of these at the same time will get really confusing. Sorry to inconvenience you. Terry 😓

Hi @TerryE I'm very understand, it doesn't matter, SDK 1.5 is a big change, all push request may pending until 1.5 done.

So, this can be closed in favor of #887, right?

[TerryE]

#887 is a rebase and commit so only shows the one commit, but we need to go through this carefully. However, since these has been superseded by #887, I fell that we can close this multipe-commit anologue.
