244 Here is the raw text from Paul: 244 <title>BitBake</title>
245 <literallayout class='monospaced'> 245
246* BitBake - Fix continuation on last line of a comment: if a comment ends in a line continuation (\) then the next line must also be a comment; any instance where this is not the case will now trigger a warning. Either remove the continuation character or make the next line a comment as well. 246 <para>
247 247 Differences include the following:
248* BitBake - The runtime package specific variables (RDEPENDS, RRECOMMENDS, RSUGGESTS, RPROVIDES, RCONFLICTS, RREPLACES, FILES, ALLOW_EMPTY, and the pre/post install/uninstall script functions pkg_preinst, pkg_postinst, pkg_prerm, and pkg_postrm) should always have a package name override, for example RDEPENDS_${PN} for the main package instead of RDEPENDS; there are now stricter checks at parse time to ensure this is done in all recipes. 248 <itemizedlist>
249 249 <listitem><para><emphasis>Comment Continuation:</emphasis>
250* Build Behavior - Shared state code has been optimised to avoid running tasks that are not really needed; for example, bitbake -c rootfs some-image from shared state will no longer populate the target sysroot since that is not necessary - the system just needs to extract the output package contents, re-create the packages and construct the root filesystem. This is unlikely to cause any problems unless you have missing declared dependencies. 250 If a comment ends with a line continuation (\) character,
251 251 then the next line must also be a comment.
252* Proxies and Fetching Source - A new oe-git-proxy script has been added to replace previous methods of handling proxies and fetching source from Git. See meta-yocto/conf/site.conf.sample for information on how to use this script. 252 Any instance where this is not the case, now triggers
253 253 a warning.
254* Build Behavior - When scanning for files in SRC_URI, the system now uses FILESOVERRIDES instead of OVERRIDES for the directory names. All of the sensible values previously in OVERRIDES are now in FILESOVERRIDES as well, however if you relied upon an additional value you added to OVERRIDES you may now need to add it to FILESOVERRIDES (unless you are already adding it via the MACHINEOVERRIDES or DISTROOVERRIDES variables, where this is appropriate). 254 You must either remove the continuation character, or be
255 255 sure the next line is a comment.
256* Remote Debugging - Support for remote debugging with the Eclipse IDE has been split out into a separate image feature (eclipse-debug) corresponding to the packagegroup-core-eclipse-debug package group. (Previously this was included in the tools-debug image feature which corresponds to the packagegroup-core-tools-debug package group.) 256 </para></listitem>
257 257 <listitem><para><emphasis>Package Name Overrides:</emphasis>
258* Variables - SANITY_TESTED_DISTROS now uses a distro ID composed of the host distributor ID followed by the release, rather than the description field being used previously (so "Ubuntu 12.10" becomes "Ubuntu-12.10"). If you aren't setting this variable (or are setting it to "") you don't need to worry about this. 258 The runtime package specific variables

269- gtkhtml2 removed - now in the meta-oe layer 269 <filename>pkg_postinst</filename>,

286- evieext removed - removed from xserver in 2008 286 <itemizedlist>
287- xf86rushproto removed - dependency in xserver was spurious and was removed in 2005 287 <listitem><para><emphasis>Shared State Code:</emphasis>
288- libxfontcache / xfontcacheproto removed - removed from the Xorg server in 2008 288 The shared state code has been optimized to avoid running
289- libxp / libxprintapputil / libxprintutil / printproto removed - the XPrint server was removed from Xorg in 2008 289 unnecessary tasks.
290- libxtrap / xtrapproto removed - functionality was broken upstream so it was removed 290 For example,
291 </literallayout> 291 <filename>bitbake -c rootfs some-image</filename> from
292 </para> 292 shared state no longer populates the target sysroot
293 since that is not necessary.
294 Instead, the system just needs to extract the output
295 package contents, re-create the packages, and construct
296 the root filesystem.
297 This change is unlikely to cause any problems unless
298 you have missing declared dependencies.

301 When scanning for files in

303 the build system now uses <filename>FILESOVERRIDES</filename>
304 instead of <filename>OVERRIDES</filename> for the directory
305 names.
306 In general, the values previously in
307 <filename>OVERRIDES</filename> are now in
308 <filename>FILESOVERRIDES</filename> as well.
309 However, if you relied upon an additional value
310 you previously added to <filename>OVERRIDES</filename>,
311 you might now need to add it to
312 <filename>FILESOVERRIDES</filename> unless you are already
313 adding it through the <filename>MACHINEOVERRIDES</filename>
314 or <filename>DISTROOVERRIDES</filename> variables,
315 as appropriate.

339 separated into an image feature

341 <filename>packagegroup-core-eclipse-debug</filename> package group.
342 Previously, the debugging feature was included through the

353 The <filename>SANITY_TESTED_DISTROS</filename> variable now uses a
354 distribution ID, which is composed of the host distributor ID
355 followed by the release.
356 Previously, it was composed of the description field.
357 For example, "Ubuntu 12.10" becomes "Ubuntu-12.10".
