OnChip and SiFive, two groups aiming to develop and release RISC-V platforms, have announced they will collaborate. From OnChip's crowdfunding campaign:
Ever since SiFive's HiFive1 campaign was launched just a week after we launched Open-V back in November, we've both been getting a lot of questions about how we might collaborate. It's taken a while, as these things do, but we finally have a concrete answer we think will benefit everyone, not least the RISC-V community. Here's how we're collaborating:
...
Open-V Will Use the SiFive E31 CPU Coreplex
...
All Open-V Peripherals Will Be Compatible with SiFive Chips
...
SiFive Will Donate Wafer Space in a May 2017 Tapeout
...
OnChip Will Contribute to the Free Chips Project
Sounds like good news for those hoping for RISC-V and open hardware designs to become tangible objects.
Note that the SiFive HiFive1 campaign was successful and has already shipped to some backers while the OnChip OPEN-V campaign looks like it will not reach its goal.

Whoa...
These new PIC10F32X variants are based on the standard mid-range architecture (vs. the baseline for the PIC10F2XX family)
I made a little dev kit to play with the 10F2XX series some years ago and I see time marches on! That's quite a featureful little chip you've found there!
A 555 timer is about the same price now. A couple years back a 10F2XX cost more than a 555 but you could program it and reprogram it and it takes zero passives for a simple timer so arguably it came out ahead. The 10F2XX series being a bit crude and limited its a fair comparison...
I actually invested in a SMD ZIF socket for my 10F2XX project to make a little dev board thingy and I should see if its pin compatible with the 10F3XX series. Otherwise if you don't use a ZIF socket programmer you have to solder in a PICKIT header so you can program the darn thing.
I never did anything terribly useful with the 10F I was going to develop a little I2C talker that could squirt out config to something like a DDS oscillator so it kinda held its programming. You can buy COTS kits to do that. Much more elegantly (although larger) than my design. The qrplabs progrock is basically what I was going to make although much smaller of course, and an older generation DDS oscillator, for obvious reasons.
A lot of the fun of the 10F2XX was simply using the weirdest smallest little microcontroller I had ever used, just because. I could solder together something the size of an altoids tin that contains maybe 50 processors although I have no idea what I'd do with that...

I used microchip's programmer adapter to program the SOT23 chips:

I just looked at the datasheets, and as far as ICSP is concerned, the 10F220/222 have the same pinout as the 10F320/322. I too chose this chip because it was so tiny and inexpensive. Amazing to see what something so small can be used for.
I'm also really fond of the 12F1571/1572.
