Cockos has updated Reaper to v1.857.

Changes since v1.852:

• Forced ripple editing of tempo envelope when "attach envelopes to items" is off and ripple editing is set to "all".
• "insert empty space in selection" uses beats if project/view mode is set to beats.
• Fixed CD burning after rendering.
• FX parameter envelope toggling fixes.
• Option to arm FX parameter envelope from MIDI learn dialog.
• Actions to set track record mode, monitoring, etc.
• Better track templates menu (subdirectories).
• Added ix/schwa MIDI/channel JS FX.
• Clicking the master track shows master FX if FX-follows-track selection set.
• Fixed bug where tempo envelope is sometimes not affected by "insert time in project" etc.
• Better timemap rebuilding when using ripple editing.
• Splitting items resets keyboard input to items.
• Updated a lot of folder solo+routing logic and meter displays with complex routing.
• Solo overrides mute on post-fader aux sends, hardware outputs.
• Improvements to file system folder browsing dialogs.

• Fixes to/better shaping MIDI CC actions for metronome volume control, track volume controls.
• Increased max MIDI assignable tracks to 99.
