Tuomo updated the license in a mailing list post:

 https://lists.berlios.de/pipermail/ion-general/2009-September/001730.html

This new license removes the 28-day clause.
Add diagnostic logging

track down a valgrind warning
Update license according to copyright holders wish

It is unusual to change a license like this, but because the difference is
well-documented it should be OK in this case.

Merge commit 'cc33ee990873f98008659efc46e7fc3c90aac26b'
Remove title truncation logging

Seems like the valgrind logging I saw before was something to do with local
library version mismatches, false alarm.
Allow logging of RandR events
Add kludge for IntelliJ IDEA transients
When a clientwin refuses focus, focus its parent

Specifically, this will make sure that when a clientwin refuses to take the
focus, we give the enclosing frame the focus. This makes sure not being able
to focus the clientwin doesn't interfere with the normal way tabs/frames work.

Intended to fix https://sourceforge.net/p/notion/bugs/60/ . Hopefully doesn't
reintroduce https://sourceforge.net/p/notion/bugs/53/ ...
Merge branch 'fixfocusbug'
Leave the focus alone when sharing a parent

.. depth is kind of arbitrary, this seems to be the sweet spot where it works
with my testcases (IntelliJ IDEA and oclock)...
Clientwin refusing focus passes it to tile parent

Treat the special case more like a special case, fixes a regression where
IntelliJ IDEA mini-windows popping up when completion options exceed the size
of the popup would get focused while they shouldn't.
Kludge IntelliJ IDEA splash popup to be transient
added debug-printing of parents or managers of a region
focuslist is now populated after a delay

The focus list is no longer immediately updated. This is nice because you can
now search for a window by quickly cycling through some windows without them
showing up near the top of the focus list. This allows the
go-to-previous-windows functions to keep working as the user intends. This
behavior is enabled with a config option: 'focuslist_insert_delay'. This is
turned off by default.

Before this patch, the currently-focused region was assumed to be the one at the
top of the focuslist. This is no longer true 100% of the time, so those two
things are now tracked separately
added debug-printing of the focus list
log.c: local functions are static
activity notifiers can now be displayed on ALL screens

Added new option "activity_notification_on_all_screens" that causes activity
notifiers to be displayed on ALL the screens, not just the screen that contains
the window producing the notification. This is only relevant on multi-head
setups. By default this is disabled.
build: all .o objects no longer depend on exports.h

The build system had an unconditional dependency declared:

 %.o: %.c $(EXPORTS_H)

The result of this was that when any .c file was changed, lua would regenerate
its exports, which would then trigger a rebuild of EVERYTHING. In truth, most
things don't really depend on exports.h.

This patch explicitly declares dependencies on exports.h. The dependency
generator generates these dependencies too, but the explicit declarations are
required for the initial build, when the generated dependencies aren't yet
available
build: simplified compilation rules for toplevel rules.mk

There were multiple %.o:%.c rules defined that more or less said the same thing.
This patch consolidates them. There's much similar boilerplate in other modules
(libtu/build/rules.mk for instance) that this patch doesn't touch. It would be a
good idea to consolidate all the logic.
build: mkexports rule is now a written as a multi-target-generating rule
build: dependencies are now ALWAYS generated. Also simpler implementation

Previously you didn't get header dependencies, unless you asked for them. Now
this information is always generated, and it's done together with the
compilation step. This is simple and robust. The only way a dependency
relationship is missed is the first time you add a #include. Rebuilding that
source file once adds the dependency
