Changes between GMP version 4.1.3 and 4.1.4

• Bug fix to FFT multiplication code (crash for huge operands).
• Bug fix to mpf_sub (miscomputation).
• Support for powerpc64-gnu-linux.
• Better support for AMD64 in 32-bit mode.
• Upwardly binary compatible with 4.1.3, 4.1.2, 4.1.1, 4.1, 4.0.1, 4.0, and 3.x versions.

New features of GMP 4.1.3

• Bug fix for FFT multiplication code (miscomputation).
• Bug fix to K6 assembly code for gcd.
• Bug fix to IA-64 assembly code for population count.
• Portability improvements, most notably functional AMD64 support.
• mpz_export allows NULL for countp parameter.
• Many minor bug fixes.
• Upwardly binary compatible with 4.1.2, 4.1.1, 4.1, 4.0.1, 4.0, and 3.x versions.

New features of GMP 4.1.2

• Important bug fixes.
• Upwardly binary compatible with 4.1.1, 4.1, 4.0.1, 4.0, and 3.x versions.

New features of GMP 4.1.1

• Bug fixes.
• Upwardly binary compatible with 4.1, 4.0.1, 4.0, and 3.x versions.

New features of GMP 4.1

• Bug fixes.
• Speed improvements.
• Asymptotically fast conversion to/from strings (mpz, mpq, mpn levels), but also major speed improvements for tiny operands.
• Further improved documentation.
• Major speed improvments for HPPA 2.0 systems.
• Major speed improvments for UltraSPARC systems.
• Major speed improvments for IA-64 systems (but still sub-optimal code).
• Extended test suite.
• mpfr is back, with many bug fixes and portability improvements.
• New function: mpz_ui_sub.
• New functions: mpz_export, mpz_import.
• Optimization for nth root functions (mpz_root, mpz_perfect_power_p).
• Optimization for extended gcd (mpz_gcdext, mpz_invert, mpn_gcdext).
• Generalized low-level number format, reserving a `nails' part of each limb. (Please note that this is really experimental; some functions are likely to compute garbage when nails are enabled.)
• Nails-enabled Alpha 21264 assembly code, allowing up to 75% better performance. (Use --enable-nails=4 to enable it.)
• More we've forgotten about...
• Upwardly binary compatible with 4.0, 4.0.1, and 3.x versions.
