2003-12-16 cairo-0.1.17 Carl Worth <cworth@isi.edu>
===================================================
Snapshot 0.1.20 (2004-04-06 Carl Worth <cworth@isi.edu>)
========================================================
New pattern API
---------------
David Reveman has contributed a new pattern API which enable linear
and radial gradient patterns in addition to the original surface-based
patterns. The significant new top-level functions are:
cairo_pattern_create_linear
cairo_pattern_create_radial
cairo_pattern_create_for_surface
cairo_pattern_add_color_stop
cairo_set_pattern
Any code using the old cairo_set_pattern, (which accepted a
cairo_surface_t rather than a cairo_pattern_t), will need to be
updated.
Update to XCB backend
---------------------
The XCB backend is now enabled by default, (use ./configure
--disable-xcb to turn it off).
Faster clipping
---------------
Graydon Hoare has added optimizations that make cairo_clip much faster
when the path is a pixel-aligned, rectangular region.
Bug fixes.
Snapshot 0.1.19 (2004-02-24 Carl Worth <cworth@isi.edu>)
========================================================
New PNG backend
---------------
Olivier Andrieu contributed a new PNG backend. It builds on the
existing image backend to make it easy to render "directly" to a
.png file. The user never needs to deal with the actual image
buffer. The significant new functions are:
cairo_set_target_png
cairo_png_surface_create
The PNG backend is not enabled by default so that by default there is
not a new dependency on libpng. Use ./configure --enable-png to enable
this backend.
Snapshot 0.1.18 (2004-02-17 Carl Worth <cworth@isi.edu>)
========================================================
Path query functionality
------------------------
It's now possible to query the current path. The two new functions
are:
cairo_current_path
cairo_current_path_flat
Each function accepts a number of callback functions that will be
called for each element in the path (move_to, line_to, curve_to,
close_path). The cairo_current_path_flat function does not accept a
curve_to callback. Instead, all curved portions of the path will be
converted to line segments, (within the current tolerance value). This
can be handy for doing things like text-on-path without having to
manually interpolate bezier splines.
New XCB backend
---------------
Jamey Sharp has contributed a second X backend that uses the new, lean
XCB library rather than Xlib. It cannot currently be compiled at the
same time as the Xlib backend. See ./configure --enable-xcb.
Build fixes for cygwin.
Bug fixes.
Snapshot 0.1.17 (2003-12-16 Carl Worth <cworth@isi.edu>)
========================================================
Better text support

RELEASING Normal file

So far, cairo hasn't reached an initial release. But we can still form
good habits now by practicing the release process with the current
snapshots.
10 easy steps to creating a new cairo snapshot
==============================================
1) Commit code with a significant new feature or backwards
incompatibility.
Either of these events triggers the need for a new snapshot.
Users of cairo snapshots need to be able to specify snapshot
version numbers in order to get access to a specific set of
features.
2) Verify that the code passes "make distcheck"
Running "make distcheck" should result in no warnings or
errors and end with a message of the form:
=============================================
cairo-X.Y.Z.tar.gz is ready for distribution
=============================================
(But the tar file isn't actually ready yet, as we still have
some more steps to follow).
3) Fill out an entry in the NEWS file
Sift through the information in ChangeLog since the last
snapshot. Summarize major changes briefly in a style similar
to other entries in NEWS.
4) Increment CAIRO_VERSION in configure.in
Right now, in its pre-release form, we are incrementing
CAIRO_VERSION for each snapshot but we are not changing the
libtool shared library version information. Until now, we've
only incremented the sub-minor version. We'll invent rules for
incrementing major and minor numbers when the time is right.
5) Commit the changes to NEWS and configure.in
Don't forget to fill out the ChangeLog just like with any
other commit. It's especially important to mention the new
version number in the ChangeLog.
6) Run "make distcheck" to generate the final tar file with the
correct version number.
7) Copy the resulting tar file to the cairo snapshots distribution
directory:
scp cairo-X.Y.Z-tar.gz cairographics.org:/home/www/cairo/snapshots
8) Tag the entire source tree with a tag of the form SNAPSHOT_X_Y_Z:
cvs tag SNAPSHOT_X_Y_Z
9) Send a message to cairo-announce@cairographics.org to announce the
new snapshot.
This is as simple as cutting and pasting the new section of
the NEWS file into the body of the message.
10) Sit back and relax in confidence, (or brace yourself for a flood
of new bug reports). It's up to you!
