[Sorry for the re-post, I did not know had to subscribe to the Fedora list.]
Hello Pravin Satpute et al.,
I am one of the maintainers of the liberation-fonts package in Debian (it is called fonts-liberation there [1]) and I am a bit concerned about the current state of development and the future of these fonts. I have read that the new release 2.00.1 based on Google Crosscore fonts has been defered from Fedora 18 because of rendering regressions [2]. However, since then development has apparently stopped in the GIT repository [3].
Have these rendering regressions been identified? Are they going to get addressed in the fonts or in other parts of the font rendering stack?
Will there be another release of the liberation-fonts in the short term or have these fonts been defered altogether in favor of another font family?
Thanks for your replies,
- Fabian

As you might have already read. Though Liberation 1.0 and Liberation 2.0 has same outline in source files the difference is the Hinting instructions. Hinting instructions differ in both. Due to community preferring old Liberation 1.0 hinting. Decision is made to go with Liberation 1.0.
Have these rendering regressions been identified? Are they going to get addressed in the fonts or in other parts of the font rendering stack?
Yes, Regression was identified. In fact i am also thinking on this line. We have couple of bugs pending [4][5] in Fedora against Liberation 1.0 to add some more characters. At the same time the same characters are already available in Liberation 2.0.
Problem is Liberation 1.0 and 2.0 License are incompatible (OFL and Liberation) so we can't copy Liberation 2.0 huge glyph set to Liberation 1.0.
Option is 1. Tweak/Modify Liberation 2.0 hinting instructions to match Liberation 1.0. That is big task 2. Adding more glyphs to Liberation 1.0, this is also big one.
Presently nothing is happening on this both option.
Will there be another release of the liberation-fonts in the short term or have these fonts been defered altogether in favor of another font family?
No. Liberation 1.0 is not deferred in favor of other font. Since there is no alternative font providing same crisp hinting effect and same time have more glyph coverage. Fedora still uses Liberation 1.0 and if there are any major bugs upstream is ready to fix and make new releases.
What version of Liberation does Debian ships presently?

Could this be related to the following bug reported in Debian BTS?

Alright, so the current plan is "wait and see what happens"?

Yes, looks same. I will fix this in next couple of week and will do next release of Liberation 1.0

Yeah. no option. At least will fix the major issues. So we can say in maintenance mode no new development.

http://patch-tracker.debian.**org/package/fonts-liberation/**1.07.2-6http://patch-tracker.debian.org/package/fonts-liberation/1.07.2-6
Looks good.

FWIW, I have prepared packages for fonts-liberation 2.00.1 in our GIT repository in the "experimental" branch. Since release from version 2 onward lack the sans-narrow variant due to license incompatibilities, I have forked the current v1 packaging to only include this variant. It is intended to get installed as a supplement to the v2 package and can be found in the "sans-narrow" branch.
While at it, the "master" branch contains fixes for multi-arch installations and should probably get uploaded to unstable ASAP.

In the liberation-fonts-1_07_3 branch in GIT, the fix for 715309 (hinting problem of Liberation Sans Bold character "u" at particular point size) is currently missing. Is that an oversight?

Apologies i missed this email :( I have fixed this issue in the upstream 1_07_3 branch with some other fixes. See changelog [1]
I am on the way for next release of liberation fonts waiting for fixing bug. [2] This is bit risky bug considering hinting instructions for "l" character in Mono fonts.

Hello Pravin et al.,
now that we have the croscore fonts available in Debian, too, I really wonder what we need liberation v2 fonts for? I mean, are they anything more than a rebranded version of the croscore fonts? And if yes, what benefit do they bring over just using the croscore fonts?
Or asked differently: Shouldn't we just decide to abandon the liberation fonts and ship croscore fonts instead? Or what would we be missing then?
Best regards,
- Fabian

croscore fonts are rebranded and relicensed (OFL) versions of the liberation fonts :)
And if yes, what benefit do they bring over just using the croscore fonts?

They have different hinting styles.

This might be the relation between liberation v1 and croscore, but then in turn liberation v2 was based on croscore.
They have different hinting styles.
Again, I believe this is only true for liberation v1 and croscore. I have yet to find a difference between liberation v2 and croscore in this regard.

Good question.
1. Croscore Vs Liberation 1.07.3: Hinting bytecode is not same and that is what the reason we reverted forked version of Liberation2 in Fedora from Libreation2 to Liberation1.
2. Croscore Vs Liberation 2: Yes. Liberation2 has more improvements than Croscore version which we forked earlier. If you see Changelog [a] Visible one is support for Serbian glyphs support. Other bugs fixes are
Resolved "Glyphs with multiple unicode encodings inhibit subsetting" #851790 and some other bug fixes #851791, #854601 and #851825
I am on the way to improve "l" shape before the next release so it will be less confusing in small sizes. [b]
In the long term i would like to improve hinting instructions of Liberation2 so it can match with liberation 1.07.3 and we will not required to maintain two different versions. But i am not sure how much efforts required in this. Some contribution will definitely help.

As written above is the difference.

Thank you so much for your reply!
So at the moment it makes sense to keep both (or even all three) variants around until it finally turns out which one will supersede all the others. ;)
