From b3adb1eb3e9a087f95e43f8af5e5290d92a6e943 Mon Sep 17 00:00:00 2001 From: Robb Matzke Date: Fri, 9 Aug 2002 09:55:31 -0500 Subject: [svn-r5859] ./hdf5-devel/release_docs/RELEASE.txt Purpose: Merged from 1.4 branch Description: API tracing improvements Platforms tested: Linux (--disable-hsizet didn't work before my changes and still doesn't work, but --enable-hsizet is fine). Note: This checkin includes temporary code in H5FDmpiposix.c to turn off GPFS byte range token prefetches on ASCI/Blue. Once the HDF5 API supports the necessary prerequisite functionality this temporary code can be migraged up above HDF5. --- release_docs/RELEASE.txt | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/release_docs/RELEASE.txt b/release_docs/RELEASE.txt index d7db7d5..cface4b 100644 --- a/release_docs/RELEASE.txt +++ b/release_docs/RELEASE.txt @@ -192,6 +192,26 @@ Tools Documentation ------------- + o Library + ========= + o General + --------- + * API tracing has been improved.
