    libsframe: bump version to 2.0
    
    Remove LIBSFRAME_1.1, LIBSFRAME_1.0 nodes and add a new LIBSFRAME_2.0
    node (non-inheritance version) to create new global versioned symbols.
    Also announce libsframe.so.2 in NEWS.
    
    New APIs:
         sframe_decoder_get_flags;
         sframe_decoder_get_offsetof_fde_start_addr;
         sframe_encoder_get_flags;
         sframe_encoder_get_offsetof_fde_start_addr;
    
    Removed APIs: (already deprecated since X-2 release)
         sframe_get_funcdesc_with_addr;
    
    APIs with changed semantics:
         sframe_decoder_get_funcdesc_v2;
         sframe_encoder_add_funcdesc_v2;
         sframe_encoder_write;
    
    lisbframe/
            * libsframe.ver: Define new LIBSFRAME_2.0.
            * libtool-version: Bump the 'current' numeral to indicate a binary
            incompatible release.
    include/
            * sframe-api.h (sframe_get_funcdesc_with_addr): Remove
            deprecated interface.
    libsframe/
            * sframe.c (sframe_get_funcdesc_with_addr): Likewise.
    binutils/
            * NEWS: Announce new versioned release of libsframe.

+* New versioned release of libsframe: libsframe.so.2.  This release introduces
+  versioned symbols with version node name LIBSFRAME_2.0.  Some new symbols
+  have been added to support the new flag SFRAME_F_FDE_FUNC_START_PCREL and
+  retrieving flags from SFrame decoder and encoder objects:
+    - Addition of sframe_decoder_get_flags,
+      sframe_decoder_get_offsetof_fde_start_addr, sframe_encoder_get_flags,
+      sframe_encoder_get_offsetof_fde_start_addr.
+  This release also includes backward-incompatible ABI changes:
+    - Removal of sframe_get_funcdesc_with_addr.
+    - Change in the behavior of sframe_decoder_get_funcdesc_v2,
+      sframe_encoder_add_funcdesc_v2 and sframe_encoder_write.
+
 * On s390 64-bit (s390x), gas, ld, objdump, and readelf now support generating
   and processing SFrame V2 stack trace information (.sframe).  The assembler
   generates SFrame info from CFI directives with option "--gsframe".  The
