3 * Noteworthy changes in release ?.? (????-??-??) [?]
7 libparted: new functions to set per disk (instead of per partition) flags:
10 ped_disk_is_flag_available()
11 ped_disk_flag_get_name()
12 ped_disk_flag_get_by_name()
15 libparted: new per disk flag: PED_DISK_CYLINDER_ALIGNMENT. This flag
16 (which defaults to true) controls if disk types for which cylinder alignment
17 is optional do cylinder alignment when a new partition gets added.
19 libparted: new functions to return per-partition-table-type limits:
20 - ped_disk_max_partition_start_sector: Return the largest representable
21 start sector number for a given "disk".
22 - ped_disk_max_partition_length: Return the maximum partition length
25 new command "align-check TYPE N" to determine whether the starting sector
26 of partition N is TYPE(minimal|optimal)-aligned for the disk. E.g.,
27 parted -s /dev/sda align-check min 1 && echo partition 1 is min-aligned
28 parted -s /dev/sda align-check opt 2 && echo partition 2 is opt-aligned
29 The same libblkid and kernel version requirements apply as for --align
31 Add functions to libparted to get minimal and optimal alignment
32 information from devices:
33 ped_device_get_minimal_aligned_constraint()
34 ped_device_get_optimal_aligned_constraint()
35 ped_device_get_minimum_alignment()
36 ped_device_get_optimum_alignment()
37 The same libblkid and kernel version requirements apply as for --align
39 Add ped_disk_get_partition_alignment() function to libparted to get
40 information about alignment enforced by the disk type.
44 improved >512-byte sector support: for example, printing a table on a
45 4k-sector disk would show "Sector size (logical/physical): 4096B/512B",
46 when the sizes should have been "4096B/4096B".
48 gpt tables are more rigorously checked; before, partition entry array CRCs
49 were not checked, and we would mistakenly use the AlternateLBA member of a
50 known-corrupt primary table.
52 improved dasd disk support, in previous versions calling
53 ped_disk_new_fresh() or ped_disk_duplicate() on a dasd type PedDisk
54 would fail. This is fixed now.
56 handle device nodes created by lvm build with udev synchronisation enabled
59 * Noteworthy changes in release 2.0 (2009-10-06) [beta]
63 Parted now supports disks with sector size larger than 512 bytes.
64 Before this release, Parted could operate only on disks with a sector
65 size of 512 bytes. However, disk manufacturers are already making disks
66 with an exposed hardware sector size of 4096 bytes. Prior versions of
67 Parted cannot even read a partition table on such a device, not to
68 mention create or manipulate existing partition tables.
69 Due to internal design and time constraints, the following
70 less-common partition table types are currently disabled:
72 "bsd" and "amiga" are mostly done, but had a few minor problems,
73 so may remain disabled until someone requests that they be revived.
77 big-endian systems can once again read GPT partition tables
78 [bug introduced in parted-1.9.0]
80 ped_partition_is_busy no longer calls libparted's exception handler,
81 since doing so caused trouble with anaconda/pyparted when operating on
84 Partitions in a GPT table are no longer assigned the "microsoft
85 reserved partition" type. Before this change, each partition would
86 be listed with a type of "msftres" by default.
89 * Noteworthy changes in release 1.9.0 (2009-07-23) [stable]
93 parted now preserves the protective MBR (PMBR) in GPT type labels.

96 http://lists.gnu.org/archive/html/bug-parted/2008-12/msg00015.html
98 gpt_read now uses SizeOfPartitionEntry instead of the size of
99 GuidPartitionEntry_t. This ensures that *all* of the partition
100 entries are correctly read.

104 20081202/b7c0528d/attachment.txt
106 mklabel (interactive mode) now correctly asks for confirmation, when
107 replacing an existent label, without outputting an error message.
108 http://lists.alioth.debian.org/pipermail/parted-devel/2009-January/\
111 resize now handles FAT16 file systems with a 64k cluster. This
112 configuration is not common, but it is possible.
113 http://parted.alioth.debian.org/cgi-bin/trac.cgi/ticket/207
115 parted now ignores devices of the type /dev/md* when probing. These
116 types of devices should be handled by the device-mapper capabilities
118 http://lists.alioth.debian.org/pipermail/parted-devel/2009-April/\
121 The parted documentation now describes the differences in the options
122 passed to mkpart for the label types.
123 http://lists.alioth.debian.org/pipermail/parted-devel/2009-April/\
126 ** Changes in behavior
128 include/parted/beos.h, include/parted/gnu.h and include/parted/linux.h
129 have been removed. The symbols contained in these files (GNUSpecific,
130 ped_device_new_from_store, BEOSSpecific, LinuxSpecific, LINUX_SPECIFIC)
131 were moved to the individual files that need them.
133 In libparted, the linux-swap "filesystem" types are now called
134 "linux-swap(v0)" and "linux-swap(v1)" rather than "linux-swap(old)"
135 and "linux-swap(new)" as in parted 1.8, or "linux-swap" as in older
136 versions; "old" and "new" generally make poor names, and v1 is the
137 only format supported by current Linux kernels. Aliases for all
138 previous names are available.
