  • Windows version is in stable phase (I didn’t change core implementation too much from Sciter 3.0).
  • Mac OS X is in beta phase with following known issues so far:
    • Work on master.css (default OS theme styling) is not complete yet. Expect some abnormalities in standard input renderings.
    • HTTP/HTTPS client is not complete yet so Element.request() calls (a.k.a. AJAX) will fail on http:// urls.

Note, API changes:

  • sciter.dll and sciter-osx.dylib expose single function SciterAPI() that returns pointer to "API interface table" – structure that contains all functions that used to be exposed directly in Sciter 3.0. Among other things this allows to use inspector.dll from statically linked Sciter code and to load Sciter DLL with greater flexibility. See SAPI() loader function.
  • All old API functions are implemented as inlines, like:
      inline LPCWSTR SCAPI SciterClassName () { return SAPI()->SciterClassName(); }
    so it is enough to recompile existing applications in order to use new API.
  • Mac OSX version does not have SciterProcND() for obvious reasons, use SciterCreateWindow() instead, it will create Sciter’s NSView instance inside its own NSWindow.
  • SciterCreateWindow() works on Windows too. You can use it to create standalone Sciter windows.

Fixes from latest ( version:

  • Fix of Event.x/yRoot computation
  • CSS++, mapping: left-to-right( alignment ), switches text-align:left to text-align:right and also does this for horizontal-align. It does NOT switch text-align:start | end; values.
  • Fix of text-overflow: ellipsis in GDI+ mode.
  • view.dialog() fix of custom frame, "resizeable" interpretation.
  • GDI+, rounded border rendering fix.
  • [tiscript, regexp] infinite loop on some types of REs in string.split(re).
  • [+plus] glibc++ compatibility fixes.
  • <img> fix of border rendering (default styling issue)
  • better shutdown handling (fonts)

Builds: win32, win64, osx64
