is the MD5 checksum of its contents.
"timestamp" means the signature of a source file
is its timestamp (modification time).
-When using "timestamp" signatures,
-changes in the command line will not cause files to be rebuilt.
+There is no different between the two behaviors
+for Python
+.BR Value ()
+node objects.
"MD5" signatures take longer to compute,
but are more accurate than "timestamp" signatures.
The default is "MD5".
- Have ParseConfig() recognize and supporting adding the -Wa, -Wl,
and -Wp, flags to ASFLAGS, LINKFLAGS and CPPFLAGS, respectively.
+ - Change the .sconsign format and the checks for whether a Node is
+ up-to-date to make dependency checks more efficient and correct.
+
From Gary Oberbrunner:
- Add a --debug=presub option to print actions prior to substitution.
import anydbm
SConsignFile('.sconsign_file_name', anydbm)
+ - The internal format of .sconsign files has been changed.
+ This may cause warnings about "ignoring corrupt .sconsign files"
+ and rebuilds when you use SCons 0.96 for the first time in a tre
+ that was previously gbuilt with SCons 0.95 or earlier.
+
- The scan_check function that can be supplied to a custom Scanner now
must take two arguments, the Node to be checked and a construction
environment. It previously only used the Node as an argument.
