 This file records noteworthy changes.
 
+1.6.1 (18 July 2011)
+* Fixed several internal assertions for the debug version of GiNaC.
+* More verbose report of (auto-)configuration problems.
+* Fixed a compile problem with ginsh using gcc 4.6.
+
+1.6.0 (22 May 2011)
+* Fixed compilation issues with clang.
+* Fixed compilation issues with VC++.
+* Fixed a segfault in fsolve() and improved its numerical algorithm.
+* Fixed several memory leaks in power::eval().
+* Fixed the substitution algorithm that led to wrong results (exp(log(x))->x).
+* Fixed a bug in add:eval() (real_part() had returned wrong results).
+* Fixed infinite loop bug when unarchiving realsymbol and possymbol.
+* Fixed bugs in the GCD code.
+* Fixed empty string bug in symbol::get_name().
+* Fixed bugs concerning STL vector sizes that can potentially cause segfaults.
+* Fixed a bug in is_polynomial().
+* Removed autogen dependencies.
+* Improved simplify_indexed() algorithm.
+* Changed the connection between library version and package version.
+* power::series() can handle now more expressions with singularities in the exponent.
+* Added conjugate() methods to functions cosh, sinh, tanh.
+
+1.5.8 (06 July 2010)
+* Changed default behaviour of conjugate() for user-defined functions to avoid
+  wrong evaluations. A user-defined conjugate_func must now be explicitly
+  registered.
+* Fixed: Parser now handles abbreviations as advertized in the manual.
+* Fixed two bugs in the GCD code (one infinite loop, one miscalculation).
+* Fixed dangerous iterator use.
+* Fixed a memory leak in excompiler.
+* Fixed several syntax issues wrt to gcc 4.5 and wrt to compile option -std=cxx0x.
+* Fixed a wrong URL and a texinfo problem in the manual.
+* Added degree_vector() utility function.
+
+1.5.7 (29 March 2010)
+* Fixed a bug in the GCD code (infinite loop in pgcd()).
+* Fixed a bug in atan2() (division by zero error for atan2(x,0) if x is a
+  negative and composite term).
+* Products now correctly set info_flags::negative and info_flags::negint.
+
+1.5.6 (28 January 2010)
+* Fixed compile problem with gcc 3.4.
+* Improved excompiler: The ginac-excompiler script will only be installed if
+  excompiler is supported and enabled.
+
+1.5.5 (04 November 2009)
+* Correct libtool versioning.
+
 1.5.4 (02 November 2009)
 * Default parser now can again read in user defined classes.
 * Add mul::info() and add::info() support for numeric info_flags (GiNaC now can
