It didn't appear right away, unlike the other titles released in today's batch of Kagura Games titles.

I didn't see an announcement for the RimWorld Biotech DLC. It's out now, as scheduled.

EDIT: HA! Moments later, GOG's "notify me of new releases" finally notified me. After I bought it an hour ago. As usually happens, I notice before the notifications.

EDIT2: Now announced. https://www.gog.com/en/news/release_rimworld_biotech_dlc

New DLCs (not mentioned in this post's right side panel):

Monster Roadtrip - Playable Character - Glitch
Monster Roadtrip - Playable Character - Hazel
Monster Roadtrip - Playable Character - Juan
Monster Roadtrip - Playable Character - Zoe

Two new "DLCs":
- Twinsen's Little Big Adventure Classic - Original Edition
- Twinsen's Little Big Adventure 2 Classic - Original Edition

Any difference between these and what was available before the "classic editions" were added?
I mean, have:
LBA1:
- old: setup_lba_2.1.0.22.exe - 402,001,360 bytes
- new: setup_twinsens_little_big_adventure_classic_-_original_edition_3.2.3.1_(58613).exe - 263,006,936 bytes
(plus setup_twinsens_little_big_adventure_classic_3.2.3.1_(58613).exe - 266,410,288 bytes)
LBA2:
- old: setup_lba2_2.1.0.8.exe - 666,776,816 bytes
- new: setup_twinsens_little_big_adventure_2_classic_-_original_edition_3.2.4.2_(58788).exe - 525,281,152 bytes
(plus setup_twinsens_little_big_adventure_2_classic_3.2.4.2_(58788).exe - 527,472,520 bytes)

At least in terms of size, these "new originals" seem very close to the "classic editions" and much smaller than the "old originals". Just better compression?
(Never installed any, they're in the "uncertain I'll ever be interested" pile, but just wondering.)

See image for LBA1 (didn't install LBA2, but I suspect it'll be similar). Left is classic, right is classic original.

Most of the resources (Common) are identical. Classic has 5 extra bmp and 6 extra ogg. And they have very different TEXT.HQR and slightly different executables.
