Bug fix
Description:
Allow a user block to be "inserted" in front of a file (probably by
writing a validly-sized userblock to a new file and then appending another
HDF5 file to the new file).
Platforms tested:
FreeBSD 4.8 (sleipnir)

Update readme
Description:
Noted that hobj_ref_t's and the objno field in the H5G_stat_t structure
can now be directly compared for equality by applications.
Bug fix
Description:
I/O on chunked datasets with point selections was not working correctly.
Solution:
Re-wrote some parts of raw data I/O routines that build the selections for
each chunk to correctly handle point selections.

Bug fix
Description:
When a non-default indexed storage B-tree internal 'K' value is set by the
user, the chunked datasets created in that file (until it is closed) use the
user's 'K' value and the data can be accessed correctly, but the 'K' value is
not stored in the file.
However, once the file is closed and re-opened, the non-default 'K' value
is lost and the data in the chunked datasets will not be able to be accessed
correctly.
Solution:
Store the indexed storage B-tree internal 'K' value in the superblock.

Description:
H5T_BKG_TEMP was accidentally removed from library code, but is used by
application's datatype conversion routines.
Solution:
Revert removal of H5T_BKG_TEMP.

Update configuration
Description:
Now that we've split the tree (Yea!), change the main trunk back to debug
on and production off.
Also, change the version # to 1.7.0
update for release
Description:
Set the version information to 1.6.0-pre1 to get ready for
v1.6 release.

h5fc and h5c++ to the new tools sections in REELASE.txt.
I added instructions for how to build HDF5 using Intel compilers
on Windows.

Bug fix
Description:
The dataset's modification time was getting set whenever raw data was
written with H5Dwrite. Unfortunately, this is a metadata change (which are
required to be performed collectively) and H5Dwrite may be called independently
from a parallel program, resulting in metadata cache corruption and/or program
hangs.
Solution:
Don't update the modification time when raw data it written. :-(
Platforms tested:

Misc. update:
Noted in release notes and also sent to Frank for updating the docs.
Code cleanup/new features.
Description:
Clean up whitespace & formatting.
Make the -S (simple) output display a dataset's modification time in UTC
rather than local timezone.
Display variable-length datatype information.
Simplified & enhanced bitfield datatype information displayed.

API tweak.
Description:
The H5Sget_select_bounds() API call was using hsize_t arrays for retrieving
the 'start' and 'end' coordinates, which is counter to the rest of the dataspace
API.
Solution:
Change the arrays to be hssize_t instead.

Purpose: Maintenance for 1.6 release
Description: HISTORY.txt was not updated in 1.5 branch since 1.2.0 release.
RELEASE.txt had a lot of redundant info that is now in HISTORY.txt
INSTALL_Windows_withF90.txt was lost in 1.5 branch.
Solution: I updated HISTORY.txt to include release history up to 1.4.5 release.
After that I removed all information related to the 1.4.* releases
from RELEASE.txt file. "Platforms Tested" section was brought up
to date based on the information provided by developers for 1.6.0 first
round of testing. RELEASE.txt still needs a lot of work.
INSTALL_Windows_withF90.txt is also a first draft, more work is needed.

Misc. update:
Purpose: Maintenance
Description: I changed release version to 1.5.54.
Email about tetsing of 1.5.53 will be send after this checkins.

Platforms tested: Done on arabica
Misc. update:
New feature/enhancement
Description:
Chunked datasets are handled poorly in several circumstances involving
certain selections and chunks that are too large for the chunk cache and/or
chunks with filters, causing the chunk to be read from disk multiple times.
Solution:
Rearrange raw data I/O infrastructure to handle chunked datasets in a much
more friendly way by creating a selection in memory and on disk for each chunk
in a chunked dataset and performing all of the I/O on that chunk at one time.
There are still some scalability (the current code attempts to
create a selection for all the chunks in the dataset, instead of just the
chunks that are accessed, requiring portions of the istore.c and fillval.c
tests to be commented out) and performance issues, but checking this in will
allow the changes to be tested by a much wider audience while I address the
remaining issues.
Platforms tested:
h5committested, FreeBSD 4.8 (sleipnir) serial & parallel, Linux 2.4 (eirene)
Feature Add
Description:
Added knob so that the programmer can enable or disable GPFS
hints during runtime instead of having it only enabled at
configure/compile time. Some of the public APIs were changed
to add an extra parameter for this option...
Platforms tested:
Blue (LLNL). It only affects the MPI/POSIX driver, so no need
to test it on non-GPFS platforms.

Update
Description:
The H5FC was already in this doc...but under "bug fixes". Removed
that since it's really a new feature.
