New libraries

  • Multiple new wrappers for C libraries:
Wrapper Description of C library
wrap_mpack mpack is a C implementation of an encoder and decoder for the [MessagePack](https://msgpack.org/) serialization format.
wrap_cairo Cairo is a 2D graphics library with support for multiple output devices. Currently supported output targets include the X Window

System (via both Xlib and XCB), quartz, win32, and image buffers, as well as PDF, PostScript, and SVG file output. Experimental backends include OpenGL, BeOS, OS/2, and DirectFB.

wrap_rsvg This is librsvg - A small library to render Scalable Vector Graphics (SVG), associated with the GNOME Project. It renders SVG files to Cairo surfaces. Cairo is the 2D, antialiased drawing library that GNOME uses to draw things to the screen or to generate output for printing.

Libraries bug fixes

  • sqlite3: fixed SQLITE text containing null character
  • web cms: updated core and authentication modules to remove potential vulnerabilities (js, svg script in url).
  • web cms: fixed a crash of the "roc" installer tool when a module had no "site" folder.

Developer changes

  • libraries: removed the *-safe.ecf as they are useless thanks to the notion of capabilities of ecf files.
