In this release significant and substantial portions of the “core library code”
have been replaced, however an attempt was made to alter little to none of the
existing public facing API. The rewrite changes the internal architecture of the
library and is a precursor to addressing long standing issues which will entail
introducing a new public API in the near future.
Breaking Changes: Nothing public API-facing
In short, the new core code replaces all the dialog, UAC core, and UAS core
related implementation in the library as well has the internal implementations
of all the Context classes as well as Session, Subscription, and UA classes.
If you are utilizing properties or methods not documented as part of the
public API, there have been significant “internal changes” as follows...
Removed completely
- Dialogs.ts
- RequestSender.ts
- SanityCheck.ts
Modified significantly
- ClientContext.ts
- InviteClientContext.ts
- InviteServerContext.ts
- PublisherContext.ts
- ReferContext.ts
- RegisterContext.ts
- ServerContext.ts
- Session.ts
- SIPMessage.ts
- Subscription.ts
