It seems that Bitmain has taken seriously the issue with their Antminer E3 ASIC miners intended for Ethash stopping to mine Ethereum Classic (ETC) recently and their upcoming inability to mine ETH as well in the very near future. To ensure Bitmain can provide efficient mining equipment for the Ethereum community, it has launched a new firmware to support the Antminer E3. This new firmware has apparently been designed to allow miners to continue using the Antminer E3, even after March 2020. This new firmware addresses the prior issue of the growth of directed acyclic graph (DAG) files, which limited the capability of the Antminer E3s for mining ETH or ETC. This new firmware will expand the usage of Double Date Rate (DDR) Memory, as more space is needed to process DAG files according to the company.
So, how long will the Antminer E3 last with the new firmware? The new firmware has been designed to better support the Antminer E3, and so Bitmain is confident that miners can continue using the hardware past April 2020. With the new firmware update, the final approximate block height of the Antminer E3 is 11,400,000, so according to calculations, mining can continue until October of 2020. ETC mining will stop again earlier than ETH due to the current DAG Epoch for Ethereum Classic being ahead with about 10 Epochs. Regardless, the new DAG size that the E3 miners would be able to handle seems to be increased to 3.97 GB based on the block number data released by Bitmain. So if you have Bitmain Antminer E3 miners you should make sure to update them with the latest firmware released to be able to extend their life to the maximum possible.

It did not take long and now the latest GMiner 2.04 GPU miner had added support for the new KAWPOW mining algorithm that RavenCoin (RVN) might/could/should/would be forking to sometime in April. The KAWPOW algorithm is a derivative of ProgPOW with parameters specific for RavenCoin, so another miner with ProgPoW support will not work unless specific RVN support is added like in the case of GMiner that already had ProgPoW support, but needed an update for KAWPOW support. Do note that support for KAWPOW is currently only available for Nvidia GPUs and that goes for ProgPoW as well. You can already test KAWPOW support on the RavenCoin test network to get ready your miner, there miner RVNt testnet tokens do not have any value though.
Besides the new algorithm being added, the latest version of GMiner addresses an issue we have noted regarding high CPU usage in Qitmeer (PMEER) support. There is a new “--trim” parameter being introduced to control additional trim round count for Cuckoo24 (Qitmeer) algorithm that should help reduce CPU load, so you can give it a try and see if it helps if you have any GPU mining rigs with lower-end CPUs that have high CPU load issue.
The GMiner miner software was originally only an Nvidia GPU miner, although some algorithms are already supported on AMD GPUs as well. Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, there is a 2% developer fee built-in the software.

The latest GMiner 2.03 GPU miner adds support for the Qitmeer (PMEER) mining, however do not be in a hurry to try mining using the Cuckoo24 algorithm that has been just added. Have in mind that the Qitmeer (PMEER) mining support comes with a 5% developer fee and is apparently CPU intensive, so you might have trouble using the latest GMiner with Qitmeer (PMEER) mining on mining rigs with most typical dual-core lower performance processors. Frankly we are a bit disappointed that the official release notes do not mention the higher developer fee for the new algorithm, nor that it is apparently heavier in terms of CPU requirements.
