# Standard ML of New Jersey
Version 110.30, November 4, 2000

> ## Summary:

> - Port to ppc Linux (thanks to Carl Pulley).

> - support for fsqrt, fptan, fcos, fsin.

> - Several CM and CMB changes.

> - Some critical bug fixes

> ### Bug fixes

> - 1514. sockets c-library broken

> - 1582. SysErr exception connecting to socket

> ### Back ends

> #### x86

> All back ends now directly generate the sqrt instruction, and the Intel x86 also generate the trig instructions to implement sine, cosine, and tangent.

> The ICFP00, PCLubIN entry shows a significant improvement as a result (most of it coming from fsqrt).

> ### CM

> #### Changes to scripts

> - "ml-build" for generating standalone programs
> - "ml-makedepend" (new!) for generating Makefile dependencies (not generally required but some project might want them)
> - "sml" - the main driver script for running SML/NJ.

> > All these scripts now accept more CM-related command-line options.

> > ml-build is faster and cleverer in avoiding unnecessary work.

> #### Other Changes

> Type of CM.mk_standalone has changed.

> All user-visible changes to CM (including the above-mentioned scripts) are documented in the CM manual. Some errors and omissions have been corrected as well.

> Bug fixes to CM's internals (e.g., missing or repeated error messages).

> Pickling/Unpickling improvements result in faster autoloading and reduce resident memory size.

> ### CMB

> Conditional compilation within the "init library". (One can now use "ifdef" and "ifndef" guards in init.cmi. This is documented in the long comment at the beginning of that file (src/system/smlnj/init/init.cmi).)

> ### Basis Library

> Added SMLofNJ.SysInfo.getHeapSuffix (for use by "ml-build").
