Bug Description


LyX 2.2.4 is the fourth and final maintenance release in the 2.2.x series.
You can download LyX 2.2.4 from http://www.lyx.org/Download/.

LyX 2.2.4 is the result of ongoing efforts to make our stable version more reliable and more stable. We have fixed a number of bugs and made several improvements.

What's new

** Updates:


- On Windows, allow to automatically bring the LyX window to top (bug 10469).

- Cache information on exportable formats (bug 9980).

- Shorten the time required to save the session state on exit.


- Updated Arabic, Czech and Japanese user interface localization.


- Mark some intentional fall-throughs in order to silence false -Wimplicit-fallthrough warnings with gcc7.

** Bug fixes:


- Fix wrong spacing in output when the font size is changed inside a center environment or a greyed out note (bugs 9598 and 10650).

- Assure properly nested \begin{lang} and \end{lang} tags even when no language package is selected (bug 10685).

- Catch "! Incomplete \if[x]" LaTeX error (bug 10666).

- Ignore LaTeX error on missing ZWNJ (ligature break) characters (bug 10727).

- Fix PDF output of clipped graphics with recent graphics package (bug 7910).

- Catch xdvipdfmx driver error that breaks XeTeX compilation (bug 10076).

- Fix caption handling in listings insets when it is split into multiple lines in the LaTeX output (bug 10705).

- Do not let the natbibapa module overwrite what the class or other packages add to the preamble.

- Assure the color package is loaded before polyglossia in preview snippets. This fixes preview image generation with polyglossia and bidi (bug 10716).

- Fix babel name of Vietnamese language. This requires now babel-vietnamese (2013ff.) instead of vietnam.ldf that was shipped with vntex previously (bug 10743).

- Fix issue with language nesting when using Asian languages (bug 10778).

- Fix bug that TeX files were not detected when reconfiguring LyX (bug 11053).


- Fix crash occurring in certain circumstances when previewing the source of a single paragraph containing a language switch (bug 10636).

- Fix crash when closing master file with full view source open (bug 10560).

- Fix crash when closing master document with dirty child while Document Settings dialog is open (bug 9979).

- Fix crash when closing master with children and grandchildren (bug 10766).

- Fix crash when pasting multiple cells into a multi-paragraph cell of a table (bug 9983).

- Fix random crash when dissolving inset (bug 10667).

- Fix potential crash when cursor enters an inset (bug 10691).

- Avoid crash when selecting long text (bug 10324).

- Fix crash with undo and child documents (bug 10643).

- Fix completely broken undo in Advanced Find & Replace edit areas (bug 10847).

- Fix crash when changing preview preferences while previewable external inset is open (bug 10785).

- Fix problem with decimal special height/width values in the Box dialog in some localizations (bug 11000).

- Remove duplicate entries from the Symbols dialog (bug 10644).

- Always show the float type in the float inset label (bug 10618).

- Show correct color name for green in the status bar (bug 10656).

- fixes to cursor positioning on mouse click for right-to-left text (bug 10569).

- Fix metrics of full-width insets when paragraph endings are shown (bug #10537).

- Fix glacial performance with ancient Hebrew text on macOS.

- Fix hole in selection for some zoom and justification values (bug 8883).

- Fix some rare cases of bad on-screen line breaking (bug #10700).

- Fix bad justification before a displayed inset (bug 10699).

- Fix selection display glitch with paragraph label (bug 10972).

- Fix cursor state after double/triple click in mathed (bug #10686).

- Avoid a case of stuck cursor after entering an inset (bug 10630).

- Fix loading of math packages in many manuals (bug 10661).

- Add note that the fixltx2e package (and so module) is obsolete as of TeXLive 2015 (bug 9361).

- Updated French user interface localization.


- Fix import of \newtheorem* declarations (bug 10622).

- Fix import of (specific) BibTeX paths (bug 7637).

- Fix import of flalign* environment (bug 10501).


- Update tex2lyx tests (bug 10800).

[Test case]
1. Launch lyx 2.2.3 from bionic. Edit a file, then save it.
2. Upgrade to lyx 2.2.4 from bionic-proposed.
3. Open the previously-saved file with the new version of lyx.
4. Modify the file.
5. Confirm that viewing the file as a PDF works.
6. Confirm that the file can be exported to other formats.

[Regression potential]
The only new feature of 2.2.4 is that it is able to read and write files in the 2.3.x format. Please note, however, that the conversion process back and forth usually will not leave one with an identical file, so we do not recommend that users of 2.2.4 try to collaborate with users of 2.3.x.

Version 2.2.3 in Bionic now cannot even read or write in 2.3.x format so users of Bionic already know that they cannot collaborate with 2.3.x users. So the regression potential is low.

Same question as https://bugs.launchpad.net/ubuntu/+source/lyx/+bug/1595358/comments/18:

This part of SRU policy is relevant here: https://wiki.ubuntu.com/StableReleaseUpdates#New_upstream_microreleases

Please could you confirm if the following are all true?

a reliable and credible test suite for assuring the quality of every commit or release,
the tests are covering both functionality and API/ABI stability,
the tests run during package build to cover all architectures,
the package has an autopkgtest to run the tests in an Ubuntu environment against the actual binary packages,

If not, this will need approval from the Ubuntu Technical Board, unless they have already granted such permission (if so, please link to that).

To one of the Lyx upstream developers, could you please answer comment #7?

@Jean-Mark, would you shed some light on comment #7?

@Robie, a micro-release update already happened in Trusty bug #1303688, it went from 2.0.6 to 2.0.8. Upstream makes sure that micro-releases are stable and only bug-fixes get cherry-picked to the stable branch from master.

I am one of the upstream developers. What I can say about this 2.2.4 version is

* we have unit tests for the code, but I would not qualify them as extensive

* as of versions 2.2.x, we have a rather extensive test repository that checks whether our file export routines (which is the main purpose of LyX after all) work well.

* as the last release of the 2.2.x series, LyX 2.2.4 has been build very conservatively, so that it would not introduce new problems. It does fix 56 bugs, among which crashes like bug #1737429.

* I do not remember of any new problem introduced in 2.2.4. Unfortunately, we did not create a "2.2.4" version in our bug tracker, so I cannot substantiate that.

* the only new feature is the possibility to read/write LyX 2.3.x files, which is very valuable in itself.

I am not sure this fulfill the SRU rules, but I want to emphasize that long term releases is the main target of a release such as this one. We have a stable release manager whose job is to sure that people can upgrade stable releases with low risk, and is twice as cautious for the last one in a series.
