Version info

4.4.1 Added convenience functions to the spline class. Fixes bug introduced in 4.4 when reading CBI data. 4.4. Updated c++ port of the WMAP likelihood routines to the 5-year data release. Use cmake as build system. Ported the gui to version 4 of the Qt library. 4.3. Added new version of WMAP and CBI likelihood routines. Added Lyman alpha constraints of Pat McDonald. Started a new directory analyze/ that will eventually hold all data routines. 4.2.1 Fixes: Bug in xcmb and cmb that prevented the computation of cold dark matter power spectra without cosmic microwave background computation. 4.2 Added WMAP-3 likelihood routines both in Fortran and in C++ (default). More convenient monte carlo driver. Used valgrind to check almost entire package for memory leaks/corruptions and the use of uninitialized variables. 4.1.4 Fixes: Compile error on certain systems. Improved drawing of likelihood contours in the gui. Now, you can superimpose likelihood regions in one plot and pick colors for each. 4.1.3 Fixes: Memory allocation error in Boomerang routine, minor error in Sne Ia core routines. 4.1.2 Fixes: Boomerang data was not shipped with previous release. 4.1.1 Fixes: Bug & compile error in newdatreader.cc. Also fixes printing of curves in gui. 4.1 Fixes: Previous versions did not add tensors and scalars together for WMAP likelihoods. New Features: Sophisticated Supernovae likelihood routines thanks to Alex Conley. Boomerang '03 likelihood added and added support for "newdat" format thanks to Georg Robbers. 4.0.1 Fixes: Compile error on certain gcc/qt combinations. 4.0 New features: Much faster integration, see astro-ph/0503277. Gauge invariant dark energy class now supports a general dark energy fluid, i.e. you can specify the sound speed etc. Georg Robbers replaced the old lensing implementation by new code resembling astro-ph/0502425. Power spectrum normalization is now in CAMB conventions, i.e. the amplitudes of the initial spectrum A_s and A_t can be chosen freely and are identical to CAMB's. Of course, you can still WMAP normalize or apply inflationary results to A_t and n_t... Power spectrum splines are now more densly sampled and therefore more robust when interpolated. The code is now gcc 4.0 compatible (runs also with earlier versions of gcc). Added MACOSX_PANTHER option to the Makefile. This gets rid of the isnan() bug which was discussed on cosmocoffee some months ago. Thanks to Luis Beca! Some minor improvments for the gui: one can switch on/off wmap normalization and choose the gauge. Increased stability of the gui. 3.0.1 Fixes: Some data files were missing in 3.0 release. Data has been re-organzied within the resources directory. 3.0 New features: Major improvement of plotting and printing of monte carlo results: Use the 1-D and 2-D tabs of the gui to marginalize and plot confidence regions. The "Plot Layou..." button invokes a sophisticated dialog for specifying labels and style for the postscript output. Fixes normalization error when calling quickWAMPNormalize() and WMAPNormalize() after each other (this should have affected no-one, as the monte carlo driver is programmed to call WMAPNormalize() only). Still, it was an error and it's fixed now. 2.1.2 Fixes: Fixed small bug in Arbitrary. Added special treatment of l=2 case in ScalarIntegrator to prevent occasional flaw. 2.1.1 Fixes: Fixed bug in makefile. Fixed crash in gui (pressing stop didn't work) 2.1 New Features: New CBI, VSA and SNe Ia data added to AnalyzeThis class. Improved accuracy. Average deviation between CMBFAST and CMBEASY is now 0.3 % for l=2...2000 Monte Carlo Markov Chain has more rugged design and two additional output files Revised 2-D Likelihood plotting in AnalyzeThis and the gui More rugged quintessence implementation. Improved arbitray equation of state support. 2.0 New Features: AnalyzeThis class added for comparison to various data sets. Monte Carlo Markov Chain example driver mc_general.cc included Alternative driver xcmb with flexible configuration file include Bessel functions are pre-calculated on startup, if none are found on disc. It is now possible to pre-calculate up to high multipoles while using only smaller multipoles in cmb calculations Complete re-write of thermal history code. Hence, cmbeasy is now independent of CMBFAST's and COSMOS' implementation. Also the time-stepping for the sources is independent from its ancestors. Arbitrary fine structure constant behaviour implemented, see the RecfastAlpha class. Added complete gauge invariant initial conditions to quintessence according to astro-ph/0304212 1.0.4 Fixes: . Rescaling to Psi = 1 in gauge invariant initial conditions had not been restricted to adiabatic case. Increased compiling compatability. New Features: Added running spectral index (research version) and WMAP data (gui). Improved features for parameters.cmb file: optical depth, omega_b*h^2 etc. instead of omega_b etc. New parameters.cmb keywords: "initialcond, tau, n_running, omega_bh2, omega_mh2". 1.0.3 Fixes: Compile error on line 2112 in cmbmainwindow.cc on some systems. Small change to Makefile: make wouldn't build bin/cmb new if only driver.cc was changed. 1.0.2 Fixes: printing using printer didn't work. Apparent error caused by non-existing "jlens.dat" in gui solved. "jlens.dat" is now in resources by default. 1.0.1 Bugfix release. Fixes: linking/compile problem caused by accidentally shipped design_cmbeasywidget.cc, tensor calculation in gui was not available, power cdm without cmb was not available, quintessence wasn't set up correctly in driver.cc. 1.0: Initial release.
