嗯,很不错。这样GW大家就不用再单独编译了。
不过TDDFT还没出来,看来遇到麻烦了

Version 4.2 of the Quantum ESPRESSO distribution is available for
download from the website http://www.quantum-espresso.org . This
release contains the following improvements over previous versions:

* HSE exchange-correlation functionals (courtesy of Hannu-Pekka
Komsa)
* New package GWW for GW calculations with Wannier functions
(courtesy of Geoffrey Stenuit and Paolo Umari)
* Grid parallelization for the phonon code
* Improved mixed openMP-MPI parallelization
* Martyna-Tuckerman algorithm for isolated systems

plus other minor improvements and bug fixes (see file Doc/release-
notes).

Everybody who is using the Quantum-ESPRESSO distribution is encouraged
to upgrade and to report problems to the mailing list.

The Quantum ESPRESSO group

简介  
ESPRESSO意为“op(E)n (S)ource (P)ackage for (R)esearch in (E)lectronic (S)tructure, (S)imulation, and (O)ptimization”。Quantum-ESPRESSO软件包基于密度泛函理论,使用平面波基组和赝势。它包含以下代码:
PWscf:电子结构,结构优化,分子动力学,振动特性和介电特性。
FPMD:Car-Parrinello可变晶胞的分子动力学程序。它基于R. Car和M. Parrinello的原始代码。
CP:Car-Parrinello可变晶胞的分子动力学程序。它基于R. Car和M. Parrinello的原始代码。
PWgui:产生PWscf输入文件的图形用户界面。
atomic:用于原子计算和产生赝势。

功能  
基态计算:
1. 自洽场总能量,力,和张量。
2. 使用迭代对角技术,阻尼动力学,和共轭梯度进行能量最小化。
3. Kohn-Sham轨道。
4. Gamma点,k点取样,各种展宽技术(Fermi-Dirac,Gaussian,Methfessel-Paxton,Marzari-Vanderbilt)。
5. 模守恒赝势和超软赝势,PAW。
6. 交换关联泛函:LDA,GGA(PW91,PBE,B88-P86,BLYP),meta-GGA,精确交换泛函,杂化泛函。
7. LDA+U。
8. Berry相极化。
9. 自旋轨道耦合和非共线磁性。
10.最大局域化函数。

响应特性(密度泛函微扰理论):
1. 声子频率,以及任意波矢的本征矢。
2. 完全声子色散,实空间的原子间力常数。
3. 平移和转动的声音求和规则。
4. 有效电荷和色散张量。
5. 电-声相互作用。
6. 三阶非谐声子寿命。
7. 红外和Raman交叉部分。
8. EPR和NMR化学位移。

从头分子动力学:
1. Car-Parrinello分子动力学。
2. Born-Oppenheimer分子动力学。

结构优化:
1. 使用准牛顿BFGS条件的GDIIS。
2. 阻尼动力学。
3. 离子共轭梯度最小化。
4. 投影速度Verlet算法。
5. 过渡态和能量最小化。
6. Born-Oppenheimer NEB。

New in version 4.2:

  * Removal of duplicated and unused routines
  * Major reorganization of the distribution itself:
    external packages no longer in the repository
  * New package GWW for GW calculations with Wannier functions
  * Grid parallelization for the phonon code, code cleanup
  * Better OpenMP+MPI parallelization
  * Real-space PP non-local projectors (experimental)
  * Martyna-Tuckerman algorithm for isolated systems
  * Better q=>0 limit for Exact-Exchange calculations
  * HSE functional
  * Bug fixes and output cleanup for cp.x autopilot
  * Parallel symmetrization in G-space

Fixed in version 4.2:

  * A few occurrences of uninitialized variables and of incorrect INTENT

  * The value of DFT set in input (instead of DFT read from PP files) was
    ignored by all codes using the data file (phonon, postprocessing, etc)

  * PW: glitches in restart (now it works also with exact exchange)

  * D3: real-space contribution to the Ewald term was incorrect, since the
    initial release. Since such term is usually very small, the error was
    also very small. Also: preconditioning was not properly implemented,
    causing unnecessary slow convergence

Incompatible changes in version 4.2:

* changed defaults:
  startingwfc='atomic+random' in pw.x (instead of 'atomic')
* calculations 'fpmd', 'fpmd-neb' removed from CP: use 'cp' or 'neb'
  instead
* calculation 'metadyn' and related variables removed from PW and CP:
  use the "plumed" plugin for QE to perform metadynamics calculations
* nelec, nelup, neldw, multiplicity variables removed from input:
  use tot_charge and tot_magnetization instead
* calculation of empty Kohn-Sham states, and related variables, removed
  from cp.x: use option disk_io='high' in cp.x to save the charge density,
  read the charge density so produced with pw.x, specifying option
  "calculation='nscf'" or "calculation='bands'"
* "xc_type" input variable in cp.x replaced by "input_dft" (as in pw.x)
* ortho_para variable removed from input (CP); diagonalization='cg-serial',
  'david-serial', 'david-para', 'david-distpara', removed as well
  Use command-line option "-ndiag N" or "-northo N" to select how
  many processors to use for linar-algebra (orthonormalization or
  subspace diagonalization) parallelization. Note that the default value
  for ndiag/northo has changed as well: 1 if ScaLAPACK is not compiled,
  Nproc/2 if Scalapack is compiled
* "stm_wfc_matching" removed from pp.x
