HDD, SSD, or Fast SSD. +Caution, you should not select SSD, if your using drive is HDD. -[ Changes from 1.3.1.8 to 1.3.1.9 ] - -Installer update -- Inno Setup was updated from v6.1.2 to v6.2.0. +[ Changes from 1.3.1.9 to 1.3.2.0 ] GUI update - Change - - Clickable link to access author's page becomes SSL. - - Appending recovery record supports 2 GB over file size. + - Fast SSD is selectable as file access mode. + - Max number of log files was increased from 100 to 1000. + - CPU usage slider was adjusted on CPU with 6 or more Cores. + - Shadow of text over progress-bar becomes more smooth. -PAR2 clients update +PAR2 client update - Change - - When source files are on NVMe SSD, verification may become faster. - - Appending recovery record supports ZIP64 format. + - Standard buffer size becomes double to decrease iteration. + - Single byte error in a single slice file may be corrected. + - Number of using threads was changed on CPU with 6 or more Cores. + - Enabling GPU won't use additional threads on multi-core CPU. + - Progress percent may move while writing blocks. - Improvement - - Simple verification will find a short slice in a tiny file. - -- Bug fix - - A stack overflow problem in quick sort function was removed. - - A bug of searching slices in a file with repeated content was fixed. + - L3 cache optimization was implemented for multi-core CPU.
