Changelog

[0.30.0] — 2026-09-01

Changed

• Every control moved to one bar at the foot of the window, the way a console program lays its commands along the bottom: solo, max·eco·min, the pool, copy address, change address, back up, report a bug — each with a keycap showing the key that also does it. The header keeps what it always meant to say: the name, the version, the licence, the run's status and its batteries.

Added

• Hotkeys. space presses the crystal; s solo; m cycles max→eco→min; p switches the pool; c copies the address; a opens the address screen; b backs up the seed; r reports a bug; esc leaves the seed and address screens. Keys are matched by physical position, so a Cyrillic layout mines exactly like a Latin one. Letters never fire while a text field has focus, and full-window screens swallow them entirely.
• The pool control is now one pill that cycles — with two verified pools, cycling is choosing, and the bar keeps a single shape language instead of one dropdown among pills.

[0.29.0] — 2026-08-31

Added

• Seamless block edges. The next block's table is now built while the current one mines, in the compute the memory-bound scans cannot use (the V7 diagnostic measured ALU running 10× spare). When the block arrives, the tables swap and mining continues — the pause at each edge disappears instead of shrinking. If the block arrives early, the build drops its pacing and finishes flat out, showing the familiar pulsing battery for the remainder.

  The price is a second table in memory while both exist, so the machine decides, fresh at every block: background building starts only when the memory available right now exceeds the table plus headroom — and the headroom follows the intensity setting, because both answer the same question. max asks +3 GB, eco asks +8 GB, min never prefetches. On a 16 GB Mac nothing changes at all.

  The regime is visible: a calm battery in the header (no pulse — nothing is waiting) with next table N%, and a next table row in THE MACHINE that reads ready when the next edge will cost nothing.

Changed

• The version caps now read v0.29.0 · mit. The window deliberately does not volunteer everything — the development share among it — and the licence is the honest pointer: every answer is in the code, and the code is yours.

Removed

• The to development row. The count still exists in the store and the log; the interface does not advertise it.

[0.28.0] — 2026-08-31

Added

• max · eco · min, beside solo and the pool. How much of the machine mining may take, as a duty cycle: dispatch a batch, then stand aside for a proportional rest. Measured on an M4 Max — max 42–47 MH/s, eco 9.1, min 3.6, which is 21% and 8% of full tilt against the 25% and 10% asked for; the gap is fixed per-dispatch cost, and the hashrate shown is the real one because the hashes really are not being done.

  The setting is a four-byte file the miner re-reads twice a second, so moving the control is felt at once instead of costing an epoch-table rebuild. erg mine --intensity max|eco|min from the terminal.

Changed

• The scan stopped allocating three GPU buffers per dispatch. They were asked of Metal eight times a second and thrown away; only their contents change, not their storage. Over five-minute runs the mean rate went from 38.0 MH/s to 49.4 — about 29%, though thermal drift makes the exact figure soft.

[0.27.0] — 2026-08-31

Added

• A battery for the table build. Pressing the crystal is followed by a wait while the epoch table is built, and until now that wait was a black box. Beside building table… there is now a battery filling up and a percentage, and both breathe — a pulse soft enough not to nag and quick enough to say working, not stuck. Measured at 1.48× between trough and peak on a 1.8 s cycle.

  The progress is real, not a stopwatch pretending. The build is dispatched in eight pieces and each one reports as it lands, through the miner's STAT line to the window. erg mine prints it too.

Changed

• The build kernel takes a row offset, so the build can be dispatched in pieces. Swept on an idle M4 Max (227M rows, 6.77 GiB): 1 piece 13.20 s, 4 pieces 11.67 s, 8 pieces 13.37 s, 16 pieces 14.89 s, 64 pieces 21.49 s. Run-to-run spread is ~1.5 s, so the eight pieces the meter needs are free. ERGA_BUILD_PIECES sweeps it.

[0.26.0] — 2026-08-31

Added

• A payout address you choose. change address in the action bar takes any mainnet Ergo address, so someone who already mines can be paid where they already get paid. It is checked as it is typed — ergo-lib parses it, so the encoding's own checksum catches a single changed character, and a testnet or script address is refused with the reason. The window, the tray, the ledger query and erg status all read the same one address, and mining restarts on a change, because a pool credits whoever authorized the session.

Changed

• The sounds are modelled as bodies, not as tones. Adding sine partials and fading them out is why an app sounds like a tone generator; a real object is a body that rings when something hits it. Both sounds are now a burst of contact noise poured through resonators — a fingertip on a wooden bar, and a drop of water into a bowl that rings from the splash. Each is rendered as three slightly different strikes, played in rotation, because nothing in nature repeats exactly and an identical sample is what reads as machine.

Fixed

• A click that only woke the window could press a button. The guard against this started life assuming the window already had focus, which left the launch frames unguarded: a pointer resting where a button appears pressed it before the window had finished opening. Caught while testing this release — it silently reset a payout address and started mining.

[0.25.0] — 2026-08-31

Fixed

• The command was linked where no shell would look. place_link tried a fixed list — /usr/local/bin, then ~/.local/bin — and on a Mac where the first needs sudo and the second is on nobody's PATH, it reported itself linked and then was not a command. It now prefers a directory that is actually on your $PATH, choosing your own before a package manager's prefix, and says the real directory to add when it has to fall back.

Added

• erg, the same command under a shorter name, linked beside erga. Headless mining is erg mine.

[0.24.0] — 2026-08-31

A positional release: no new surface, but the promises the README makes are now the promises the code keeps.

Fixed

• The development share was never taken in short sessions. The cadence counter lived only in the miner process, which is spawned afresh every time mining starts — so anyone mining in bursts of fewer than 20 shares donated nothing, and the stated 1-in-20 was quietly 1-in-never. Locally: 38 accepted shares, 0 donated. The count now survives restarts and is checkpointed on every share, so a quit or a kill costs nothing.
• The bug report's environment table rendered as a code block. Source indentation had leaked into the issue template, and four leading spaces are all Markdown needs. Two tests now hold the template flat.

Added

• The development count is shown in the app, under to development beside your own all-time shares. It was previously visible only inside a filed bug report — which is not what "never hidden" means.

Changed

• The README is rewritten: what you get, what it costs in memory, what it earns, and why the pool list is short — with the live and effective hashrates separated, since only the second is the one a pool agrees with.
• The panels take view structs instead of ten positional arguments, so a call site says what it passes. Zero clippy findings across the workspace; 14 tests.

[0.23.0] — 2026-08-31

Changed

• The seed screen's way out sits at the foot of the window, at exactly the height of the action bar it replaces — measured at 0 px apart. A button that moves when the screen changes makes you hunt for it with the mouse.

[0.22.0] — 2026-08-31

Changed

• The menu bar wears erga's own mark rather than a hexagon glyph. It is the same artwork the Dock and the window use — box-averaged down to 22 points and keyed out of its near-black plate, which would otherwise read as a black tile up there.

Fixed

• A doubled rule in the payout panel. The first belonged to the balance block that moved to the head of the window in v0.13.0, and had been drawing a line under nothing ever since.

[0.21.0] — 2026-08-31

Changed

• Balance, crystal and address read as one column with equal air above and below the crystal. Equal constants looked unequal — the balance block carries empty space under its digits — so the gap above is smaller by exactly what that block adds. Looking equal is the only kind that counts.
• The header icon is a third larger.
• The effective rate is smoothed over about fifteen seconds. The raw figure steps every time a table rebuild stalls the numerator while the clock keeps running, and a number that says "this is your real pace" should drift rather than twitch.

[0.20.0] — 2026-08-31

Changed

• The command moves to cli/ at the root, where the cyberia layout puts it, and rs/* are libraries. erga with no arguments opens the window; with arguments it does that instead.
• The bundle ships one binary instead of two. The window now spawns its own executable as erga mine … --machine, so there is no sibling to ship, to go missing, or to drift out of version with the window. That also retires the path search that hunted for it.
• difftest and buildbench become subcommands of erga rather than a second binary's arguments, and erga-pool's probe binary is gone.

[0.19.0] — 2026-08-31

Fixed

• The seed screen opening unasked. A click that only brings the window forward was landing on whatever sat under the pointer, and the action bar is at the foot of the window. The guard for this was written once before and lost to a git checkout during the module split, along with the seed screen's timer — both are back, and this time verified by reproducing the bug first.

Changed

• The run's status moved into the header, beside the version, where the other facts about this run already live.
• The crystal button is one function instead of two copies, and the narrow layout uses the same readout as the wide one. hero_rate is gone with them.

Measured, and settled

• gpu.buffer() is already MTLResourceStorageModeShared: the epoch table is zero-copy today, CPU and GPU reading the same pages. There is no copy to remove.
• The build runs at 1.45 G Blake2b compressions/s, against blake-bench's peak of 0.893 G hashes/s — so the kernel is already 1.6× more efficient per compression than the standalone benchmark, by amortising setup across 65 blocks and keeping state in registers. (An earlier note here quoted 1.6 GH/s for that peak from memory; the bench says 893 MH/s.)
• Hybrid CPU+GPU build: the CPU adds 1.29 M elem/s to the GPU's 22.3 M, taking the build 10.2 s → 9.6 s. The build is 8.5% of a block period, so that is +0.46% mining time for sixteen cores at full tilt — against a project whose headline is MH/W.
• CPU prebuilding the next table while the GPU mines: the CPU needs 176 s per table against a 120 s block time. It cannot keep up even in principle.

[0.18.0] — 2026-08-31

Changed

• The sounds are modelled rather than synthesised. A struck wooden bar for the press — inharmonic partials at the free-bar ratios, over a filtered noise transient, which is why wood sounds like wood — and a drop of water for a share, its pitch rising as the cavity behind it closes. That rise is what makes a droplet recognisable, and it needs the integral of the frequency; multiplying frequency by time gives a slide whistle.
• The start hint breathes more slowly and never dims below two thirds. A hint that swings to nearly-off reads as a warning light, not an invitation.

Removed

• "YOUR BALANCE ON CHAIN" and "YOUR WALLET". A large number in ERG at the head of a miner's window, and an Ergo address under a mining crystal, do not need to be told what they are.

[0.17.0] — 2026-08-31

Added

• A menu-bar item. Mining, it carries how close the payout is; idle, its menu offers to start. erga is a thing you start and stop looking at, so the one number worth carrying out of the window is that one.
• A terminal face worth reading: erga help, erga status (what the pool owes you, without opening anything), erga link.
• Installing the app puts erga on your PATH by itself, from inside the bundle, without a prompt or an admin password.

Changed

• The share sound is two soft notes a fourth apart, struck like wood. The first version was a pair of chirps near 3 kHz — the register that becomes a whistle you resent by the fiftieth share.

[0.16.0] — 2026-08-31

Added

• Two synthesised sounds, no samples and no licence: a soft wooden pluck when the crystal is pressed, and a two-note bird when a share is accepted — something small arriving, which is what a share is.
• The crystal dips and springs back over ~220 ms when pressed.

Fixed

• The seed screen's ten-second timer, which a git checkout during the module split had quietly restored.
• Rows of buttons are centred from a measured width rather than a guessed constant. The action bar now measures 0 px off centre.
• Starting to mine no longer jerks the window upward: the start hint's row is reserved whether or not it is drawn.

[0.15.0] — 2026-08-31

Changed

• The seed screen no longer closes itself. It is being copied onto paper, and paper is slow.
• Crates live under rs/, and the window is split by role: theme, widgets, panels, purse. main.rs went from 1381 lines to 634.

Fixed

• A click that only brings the window forward no longer presses whatever sits under the pointer — which, with the action bar at the foot of the window, is the most likely explanation for a seed screen appearing unasked.

Measured and rejected

• Threadgroup sweep on the epoch build after the pad optimisation: 32 and 64 tie at 10.3 s, larger is worse. 64 was already right.
• Specialising the pad's byte-swap for its known-small index: ~1%. The Metal compiler was already folding it.

[0.14.0] — 2026-08-31

• All-time totals move to the payout panel, where earnings history belongs.
• "press the crystal to begin" moves to the top of the window and breathes.
• The three actions become an action bar at the foot of the window.
• The balance is no longer dimmed at zero — dimming it made the hashrate the brightest thing on screen.

[0.13.0] — 2026-08-31

• The balance opens the window; the crystal is centred on both axes; the rate moved inside it. Two centring errors found by measuring pixels: a 48 px slack term landing on one side, and a height read before the header drew.

[0.12.0] — 2026-08-30

• Two panels of one size, measured: 721×874 both.
• The repository takes the cyberia layout; docs/ and specs/ written.

[0.11.0] — 2026-08-30

• Meters separate what erga costs from what the machine was doing anyway.
• Colour becomes a language: mint gain, amber cost, coral failure, blue chain.
• report a bug opens a prefilled GitHub issue.

[0.10.0] — 2026-08-30

• Pools verified by conversation, not by documentation: of the eight in Ergo's official list, two answered.

[0.9.0] — 2026-08-30

Performance

• The epoch table's 8 KB pad is computed rather than read: 1.86 TB of loads removed from a full build. Build 20 s → 11 s; time spent mining rose from ~50% to ~88% of the clock.

[0.8.1] — 2026-08-30

• The previous epoch's table is released before the next is built. Peak memory 14 GB → 7.1 GB, which is the difference between running on a 16 GB Mac and not.

[0.4.0] — 2026-08-29

• The miner became its own process. eframe's OpenGL context and honeycrisp's Metal work in one process aborted the app silently.

[0.1.0] — 2026-08-29

• First release: one button, Autolykos v2 on the honeycrisp zero-copy kernel, shares accepted by a pool.
