I did a side by side comparison in TC11_32 versus TC12_32 for librsvg and the difference is hugetc@box:/tmp$ wget http://repo.tinycorelinux.net/12.x/x86/tcz/librsvg.tcz ..... 1688 KB
so in TC_11_32 the /tmp/tcloop/librsvg/usr/local/lib/librsvg-2.so.2.40.20 is 174,688 bytes (174KB)
but in TC_12_32 the /tmp/squashfs-root/usr/local/lib/librsvg-2.so.2.46.0 is 3,631,932 Bytes (3.6 MB!)
I do not know what security was patched, (or whatever) but IMHO it is not worth this size increased.
I use the old librsvg (from TC_11_32) in abiword from TC12_32, and for my is working. The librsvg.tcz.dep is the same. YMMV.
