The -fconserve-space flag has been deprecated. The flag had no effect for most targets: only targets without a global .bss section and without support for switchable sections. Furthermore, the flag only had an effect for G++, where it could result in wrong semantics (please refer to the GCC manual for further details). The flag will be removed in GCC 4.8

The AVR port's libgcc has been improved and its multilib structure has been enhanced. As a result, all objects contributing to an application must either be compiled with GCC versions up to 4.6.x or with GCC versions 4.7.1 or later. If the compiler is used with AVR Libc, you need a version that supports the new layout, i.e. implements #35407.

The AVR port's -mshort-calls command-line option has been deprecated. It will be removed in the GCC 4.8 release. See -mrelax for a replacement.

The AVR port only references startup code that clears .bss and the common section resp. initializes the .data and .rodata section provided respective sections (or subsections thereof) are not empty, see PR18145. Applications that put all static storage objects into non-standard sections or define all static storage objects in assembler modules, must reference __do_clear_bss resp. __do_copy_data by hand or undefine the symbol(s) by means of -Wl,-u,__do_clear_bss resp. -Wl,-u,__do_copy_data.

GCC versions 4.7.0 and 4.7.1 had changes to the C++ standard library which affected the ABI in C++11 mode: a data member was added to std::list changing its size and altering the definitions of some member functions, and std::pair's move constructor was non-trivial which altered the calling convention for functions with std::pair arguments or return types. The ABI incompatibilities have been fixed for GCC version 4.7.2 but as a result C++11 code compiled with GCC 4.7.0 or 4.7.1 may be incompatible with C++11 code compiled with different GCC versions and with C++98/C++03 code compiled with any version.

added -P (--preprocess) command line option to emit preprocessed asm file

added support for undocumented HALT, TRAP and TRET opcodes

.inc and .lkr files are synced with MPLABX 1.70

fixed support for 12 bit extended instruction set, devices PIC12F529T48A, PIC12F529T39A, PIC16F527 and PIC16F570

Addition of the ability to add and connect formally defined asynchronous message ports to signal processing blocks and hierarchical blocks

the concept of PDUs (Protocol Data Units) as a convention for passing data+metadata using the new messaging ports

dozens of other features considered minor

Slight improvements to the vector plot.

Better default values for colors of plot.

Modified the confmgr to accept hex and octal values in the configuration file.

Removed the (deprecated) gnomeprint dependency. Now the complete print route relies on Pango/Cairo to generate the plot, and the GtkPrint interface to do the actual printing.

Change papersize_combo to combobox, and load the list from the available papersizes.

Adapted confmgr to accept char * from comboboxes.

Moving elements up implemented.

Converted the strange negative default values for the color definitions to their (easier to understand?) hex values.

The 'standard cable' code mostly re-written, and a few more cable types added.

Modify the xnec2c user interface so that it will, as far as possible, allow the user to save and re-open NEC2 files in the Editor window, without closing the Radiation Pattern and/or the Frequency Plots windows

replaced all the (deprecated) GDK drawing primitives with equivalent Cairo graphics equivalents (e.g. replaced gdk_draw_line() with cairo_line_to()) since Cairo provides for nicer anti-aliased drawing.

added code to save data of the structure display, radiation patterns and frequency plots into file, in a format suitable for the "gnuplot" plotting program
