DOOM Retro v2.1.1, a minor point release, is now available. It may be downloaded here, and its release notes are as follows:

• Pain elementals can now shoot lost souls through two-sided walls that have the ML_BLOCKMONSTERS flag, as is possible in Vanilla DOOM. (An example of this is at the end of MAP04 in requiem.wad.)
• The screen will no longer briefly flash if the player has a berserk or radiation shielding suit power-up and then loads a savegame or starts a new game from the menu.
• The time taken to complete a map is now restored correctly when loading a savegame.
• A bug has been fixed whereby a map would become corrupted if the player triggered a generalized line with no tag (such as when the player takes the “plunge” in MAP08 of jenesis.wad).
• A crash will no longer occur when using the maplist CCMD.
• Multiple STBAR lumps are now better handled. (For example, now the correct status bar will be displayed if JPCP_HUDjpn.wad is loaded along with JPCP_1st.wad.)
• Double-resolution yellow and grey digits will no longer be displayed in the status bar if a STBAR lump from a PWAD is used.
• The correct WAD is displayed in the output of the mapstats in DOOM II: Hell On Earth if nerve.wad is also present.
