From 418b2eb97b58e06fad074c3d465e4d4f15988f0e Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Wed, 25 Dec 2013 12:57:39 -0600 Subject: [PATCH 1/1] Update NEWS and README.WINDOWS --- NEWS | 35 +++++++++++++++++++++++++++++++++++ README.WINDOWS | 3 --- 2 files changed, 35 insertions(+), 3 deletions(-) diff --git a/NEWS b/NEWS index 5dc38020..46a2905b 100644 --- a/NEWS +++ b/NEWS @@ -1,5 +1,40 @@ Only the most important changes more recent than version 0.6 are noted here. +Version 1.6.0: + Support for extracting and updating the new version 3584 WIMs has been + added. These WIMs typically pack many streams ("files") together into a + single compressed resource, thereby saving space. This degrades the + performance of random access (such as that which occurs on a mounted + image), but optimizations have been implemented for extraction. These + new WIM files also typically use a new compression format (LZMS), which + is similar to LZMA. These new WIM files can be created with Dism using + "/compress recovery". Note: this format is used by the Windows 8 web + downloader, but important segments of the raw '.esd' files are + encrypted, so wimlib will not be able to extract such files until they + are first decrypted. + + Support for compression chunk sizes greater than the default of 32768 + bytes has been added. A larger chunk size typically results in a better + compression ratio. However, this is currently disabled for LZX + compression due to lack of interoperability with the MS implementation. + + The compression/decompression API exported by wimlib has been changed. + Now one set of functions support all supported compression formats. + + `wimcapture' and `wimappend' will now display the progress of scanning + the directory tree to capture, in addition to the progress of writing + data to the WIM. The '--verbose' option no longer does anything. The + library API change for this is the addition of several members to + `struct wimlib_progress_info_scan' available to progress callbacks. + + `mkwinpeimg' now correctly handles the '--start-script' option when the + start script is not in the working directory. + + Sequential extraction, previously required by using + WIMLIB_EXTRACT_FLAG_SEQUENTIAL, is now the default. + WIMLIB_EXTRACT_FLAG_FILE_ORDER can be used to get the old behavior + (extract in file order). + Version 1.5.3: The new LZX compressor added in v1.5.2 has been improved and is now enabled by default, except when `wimcapture' or `wimappend' is run diff --git a/README.WINDOWS b/README.WINDOWS index 93c20ddb..efa51957 100644 --- a/README.WINDOWS +++ b/README.WINDOWS @@ -37,9 +37,6 @@ ImageX are the following: * Mounting images from a WIM file is not supported on Windows. - * The LZX ("maximum") compression ratio is several percent worse than - Microsoft's implementation. - However, wimlib-imagex provides a number of advantages compared to Microsoft's ImageX, including but not limited to the following: -- 2.43.0
