感谢大家长期以来对VASPKIT的支持与喜爱，根据最新谷歌学术统计数据显示，目前VASPKIT文章引用次数逐年翻倍增加(见下图)，在顶刊中出现的频次逐渐增加(见文末附录)，而且已经入选CPC期刊近三年引用最多论文之一(见下图)。
目前VASPKIT 1.3.1最新正式版本已经开放下载，具体的更新内容简单阐述如下：
Version 1.3.1 (03 Dec. 2021) * Added a new feature to calculate transpot properties based on Boltzmann transport theory within constant relaxation time approximation (681); This utility needs to be further improved in the furture version; * Added a new feature to build vacuum slab in the specified direction (task 801); * Added a new feature to build hexagonal Moire superlattices (task 805). This utility is available only in VASPKIT Pro version; * Added a new feature to build nanotubes and nanoribbons with specified chiral vector C=n*a1+m*a2 (tasks 806 and 807). This utility is available only in VASPKIT Pro version; * Supported to read multiple parameter-value pairs on a single line in the INCAR file; * Updated the plot utility; * Fixed bug related to calculating the angular-dependent effective-mass (task 914); * Fixed bug related to fixing the selected atoms (task 402); * Fixed bug related to reading the k-labels from the KPOINTS file with line-mode; * Fixed bug related to generating the KPATH.phonopy file for D 2 materials ( (task 304); * Minor bug fixes and optimizations.
新增主要功能包括：
1. 画图模块和结构模型搭建模块进⼀步完善
* build vacuum slab in the specified direction (task 801);* build hexagonal Moire superlattices (task 805). This utility is available only in VASPKIT Pro version; * build nanotubes and nanoribbons with specified chiral vector C=n*a1+m*a2 (tasks 806 and 807). This utility is available only in VASPKIT Pro version;
2. ⽀持基于半经验玻尔兹曼输运理论计算输运性质(VASPKIT 1.3.1及以后版本)，当前版本可输出electronic conductivity, Seebeck coefficient, power factor 和electronic thermalconductivity。实现算法见⽂献(Computer Physics Communications 175 (2006) 67–71]，注意该功能⽬前处于测试阶段，未来输运性质计算模块功能将不断进⾏完善。
此外，VASPKIT中⽂⽹站https://vaspkit.cn/和中⽂论坛https://bbs.vaspkit.cn/正式上线，欢迎⼤家通过该论坛讨论VASPKIT及量化软件使⽤相关问题。
