CHANGES THE GNUSH-ELF v12.01 RELEASE:

This section describes the enhancements made and the issues fixed in the
v12.01 release.

OPTLIB:

1. The LOG10, LOG and POW functions of optimized libraries generated 
   incorrect output for SH4 Single-Only (Little Endian) and 
   SH4A Single-Only (Little Endian) targets.
   This bug has now been fixed.
   
INSTALLER: 

1. Installer now supports 'Custom Installation' and 'Default Installation'
   modes. The "Default Installation" mode is set by default where the tools 
   are installed into the default HEW (if found) and the user's username 
   and activation key are silently accepted if cached in the registry.
   
HEW (For Windows OS only):

1. Use of the Flash Development Tool (FDT) plug-ins under HEW is deprecated. 
   Hence, users are advised to download the latest version of FDT application
   and use it independently for Flash downloads.
   
KNOWN LIMITATIONS IN SH-ELF:

This section describes the known limitations in this release. We intend to
fix these issues in our future releases. 
We occasionally release maintenance packs for critical bug fixes.

Windows and GNU/Linux:

1. In newlib, the 'fmod' function fails with and without '-mrenesas' option 
   for the following single precision targets: 
   a. SH2E 
   b. SH2A-Single-Only 
   c. SH3E 
   d. SH4-Single-Only (little endian and big endian)  
   e. SH4A-Single-Only (little endian and big endian) 

2. The 'ldexp' function of optimized libraries fails for SH4-Single-Only
   (little endian) and SH4A-Single-Only (little endian) targets. 
   
3. Library Generator: Please visit the following link for the known issues 
   and limitations related to this utility:
