+* 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

* For RISC-V dis-assembler, the definition of mapping symbol $x is changed,
so the file needs to be rebuilt since 2.45 once used .option arch directives.
+* The LoongArch disassembler now properly accepts multiple disassembly
+ options given by -M, such as "-M no-aliases,numeric". (Previously only the
+ first option took effect.)

Changes in 2.44:
* Support for Nios II targets has been removed except in the readelf utility,
